Abstract:
Black women journalists have not been hampered by the sexist attitudes of men to the same degree that white women journalists have been. Since this theme was introduced a century ago, individual case studies have continued to reinforce it. Gertrude Bustill Mossell, Delilah Beasley and Ida B. Wells were nineteenth-century women whose journalistic success was supported by their male editors; Marvel Cooke, Lucile Bluford and Ethel Payne have enjoyed similar relationships in the twentieth century. Factors contributing to this tendency are that African-American women have a tradition of working outside the home, that African-American editors historically have been both journalists and racial activists, and that male editors have tended to treat African-American women journalists much as fathers treat their daughters.

Abstract:
This essay reframes both the woman suffrage narrative and narratives of African American voting rights struggles by focusing on the experiences of southern African American women between the 1870s and the 1920s. It argues that the Fifteenth Amendment remained central to their suffrage strategy long after the failure of the “New Departure” to win court sanction caused white suffragists to abandon it. As white supremacists in the South worked at the turn of the century to disfranchise black men, leading African American suffragists such as Mary Church Terrell, Gertrude Bustill Mossell, and Adella Hunt Logan called for the enforcement of the Fourteenth and Fifteenth Amendments as well as the enfranchisement of black women. After the federal woman suffrage amendment was ratified in 1920, many southern African American women encountered the same barriers to voting—obstructionist tactics, threats, and violence—that black men had faced a generation earlier. In short, for aspiring African American voters in the South, the failure of the Nineteenth Amendment to secure voting rights for black women constituted a sad sequel to the failure of the Fifteenth Amendment to secure voting rights for black men.This interpretation offers three significant interventions. It pairs the Reconstruction-era Amendments with the Nineteenth Amendment, recognizing their shared focus on voting rights. It connects the voting rights struggles of southern African Americans across genders and generations. Finally, it finds that, for some women, the canonical “century of struggle” for voting rights continued long after the Nineteenth Amendment was ratified.

Abstract:
The Irish artist Richard Mosse’s The Enclave (2013), a six-screen video, photography, and sound installation made over several years in and around Goma, Democratic Republic of Congo, was featured in the Pavilion of Ireland at the Fifty-fifth Venice Biennale and at Jack Shainman Gallery, New York. Shot with infrared Kodak Aerochrome film, Mosse’s Enclave became a locus for debates about contemporary aesthetic strategies, especially within photography, and the ethics of deploying the shock of the sublime to elicit both empathy and questioning, exposing the viewer/participant to the tensions of attraction and aversion that oscillate within the sublime. I argue that Mosse’s visual/aural strategies, by running counter to those programmed within the image supply chain dominated by mass-produced culture, set in motion jarring ambiguities that an uneasy audience must struggle with or at least decode. Mosse engages the critical points at which given sign systems break down, become porous or malleable, and where glitches and short circuits upset our blasé habits and routines of consumption. His installations pose questions about how we read meaning in the texts and images that structure our experience and our understanding of cultural representation. Thus Mosse’s work highlights the limitations of photojournalism and photography by mixing the contingent and abstract, the symbolic and political, evoking the precariousness of life as experienced in the continuing cycles of war, armed conflicts, and systematic tactics of violence that mark our era.

Abstract:
This study was conducted to investigate the morphological identification of vesicular-arbuscular mycorrhiza (VAM) on bulbous plants in the Taurus Mountains in Turkey. Thirteen soil samples and bulbous roots were taken from the rhizosphere of bulbous plants. The soils were analyzed for the number of VAM spores and chemical and physical properties. In addition, the roots were examined for infection levels, and morphological identification of VAM spores was made. All tested plants are considered mycorrhizal plants. We determined three spore species (Glomus mosseae, Glomus hoi and Scutellospora calospora) from the surveyed soils. The spore distribution rates were as follows: G. Mossea 61.54 %, G. Hoi 23.07 % and Scutellospora calospora 15.38 %. Results suggest that VAM fungal spores and root colonization display variation in rhizosphere under bulbous plants in different ecological conditions.

Abstract:
Abstract The effects of root endophytic fungus Piriformospora indica and arbuscular mycorrhizal fungus Funneliformis mosseae were investigated on some biochemical parameters in leaves and roots of Triticum aestivum cv. ‘Sardari39’ under Cadmium (Cd) stress. The experiment was carried out with inoculation treatments of F. mosseae, P. indica, F. mosseae + P. indica and no-inoculation (control) at four Cd concentrations (0, 0.3, 0.6 and 0.9 mM Cd). The results revealed that in non-inoculated plants, H2O2, malondialdehyde (MDA) and proline contents increased in leaves and roots in response to increasing soil Cd concentrations. However, guaiacol peroxidase (GPX) activity in roots and superoxide dismutase (SOD) activity in leaves and roots increased at lower Cd concentrations, while at higher Cd concentrations the rate decreased. In the presence of P. indica and F. mosseae + P. indica, H2O2 and MDA contents decreased, and proline accumulation increased in wheat leaves and roots. Also, the presence of P. indica increased GPX and SOD activities in leaves and roots. The study concluded that P. indica and F. mosseae were able to maintain an efficient symbiosis with wheat plants in soil at high Cd concentrations. However, the impact of P. indica in alleviating Cd stress was more noticeable than that of F. mosseae.

Abstract:
A composition of 16 lipid samples of sphagnum and true mosses (Bryales) growing at an average annual temperature ranging from -9.1 °C to 1.5 °C is investigated by gas chromatography-mass spectrometry. The individual composition and content of n-alkanes, fatty n-acids and their esters, n-alkane-2-ones, aldehydes, farnesylfuranes, polycyclic aromatic hydrocarbons (PAHs), tocopherols, squalene, steroids, sesqui-, di- and triterpenoids of these mosses are determined. True mosses differ from sphagnum mosses in their lower content of n-alkanes, n-alkan-2-ones, n-aldehydes, tocopherols and cyclic terpenoids, and a higher content of PAHs. Campesterol prevails among steroids of true mosses, while stigmasterol and sitosterol dominate in sphagnum mosses. Sitosterol prevails in sphagnum mosses growing in areas with a negative average annual temperature. An increase in the temperature of the habitat results in a decrease in the relative content of n-alkanes with odd number of carbon atoms in the molecule in true mosses, and a slight decrease in their average chain length in sphagnum mosses. It is shown that terpenoids are the most dependent on natural habitat conditions of mosses. This is indicated by the content of squalene, sesqui- and diterpenoids, the ratio of hydrocarbons to oxygen-containing structures of cyclic triterpenoids, and that of compounds from series of perhydropicene and cyclopentapeperhydrochryzene. The increased humidity of habitat of a moss eliminates the effect of temperature. The stability of composition of n-alkanes and n-alkan-2-ones of sphagnum mosses developing under various conditions makes it possible to consider these compounds as potential chemotaxonomic markers of sphagnum mosses in peat deposits.

Abstract:
  The present investigation was undertaken to find out efficient strains of arbuscular mycorrhiza (AM fungi) alone or in combinations with Trichoderma viride for inoculation Dendrocalamus strictus L. seedlings. The inoculated seedlings showed good response having higher plant height, phosphorous ions content in root and shoot, AM spore number and root colonization than non-inoculated (control) seedlings in both single (alone) and co-inoculation (combined consortium) experiments. T. viride showed significant growth followed by Glomus mosseae, G. fasciculatum and mixed AM with single inoculation. In co-inoculation, the best growth responses were observed with G. fasciculatum + T. viride followed by G. mosseae + T. viride, mixed vesicular arbuscular mycorrhizas (VAM) + T. viride, G. mosseae + G. fasciculatum + T. viride + mixed VAM, G. mosseae + G. fasciculatum + T. viride and G. mosseae + G. fasciculatum after 120 days and also depicted maximum increase in phosphorus content of shoot and root when compared with other inoculated seedlings. However, all the inoculated seedlings showed significant increase in phosphorus content when compared with control seedlings.

Abstract:
A field experiment was conducted to evaluate the response of AMF species with different phosphorus (P) levels for root colonization, microbial population under maize in an alluvial soil. Of all the species of mycorrhizae taken under consideration, G. mosseae along with 75% RDF of P was found to perform better in terms of root colonization, number of spores and grain yield. Application of G. mosseae @ 10 kg ha-1 + 50% P + 100% NK produced significantly higher root colonization by 177.32, 55.20, 37.75 and 101.95 per cent over the treatments 100% RDF, G. mosseae @ 10 kg ha-1 + 75% P + 100% NK, G. coronatum @ 10 kg ha-1 + 75% P + 100% NK, G. decipien @ 10 kg ha-1 + 75% P + 100% NK and control, respectively. The similar trend was observed for number of spore count. The maximum number of bacteria (40×10-5 cfu g-1 soil) was found with the inoculation of G. mosseae @ 10 kg ha-1 + 75% P + 100% NK at flowering stage. The maximum grain yield (7656.61 kg ha-1) was recorded with the application of G. mosseae @ 10 kg ha-1 + 75% P + 100% NK, which was 111.92 per cent significantly higher the control treatment. G. mosseae along with 75% RDF of phosphorus inoculation proved to be effective in modifying the soil microbe population and community structure and also in enhancing the grain yield.

Abstract:
In this work, we combined morphological taxonomy and molecular methods to investigate the intraspecific diversity of Glomus mosseae , whose global distribution has been reviewed by a survey of scientific literature and Web-available records from international germplasm collections (International Culture Collection of Vesicular Arbuscular Mycorrhizal Fungi and International Bank of Glomeromycota). We surveyed 186 publications reporting the occurrence of G. mosseae from at least 474 different sites from 55 countries throughout all continents, producing a geographical map of their distribution. The relationships among G. mosseae isolates originating from Europe (United Kingdom), the United States (Arizona, Florida, and Indiana), Africa (Namibia), and West Asia (Syria) were analyzed. The level of resolution of internal transcribed spacer (ITS) sequences strongly supports the morphological species definition of G. mosseae. An ITS – restriction fragment length polymorphism assay with the enzyme HinfI yielded a unique profile for all G. mosseae isolates, allowing a straightforward identification of this morphospecies. Genetic variability among G. mosseae isolates was revealed by the inter-simple-sequence repeat (ISSR) – polymerase chain reaction: the magnitude of genetic divergence shown by the investigated geographical isolates was higher than 50%, consistent with previous data on vegetative compatibility and functional diversity. The variability of ISSR patterns suggests that intraspecific diversity is much higher than that foreseen by morphology and rDNA regions, and should be further investigated by using other genes, such as those related to functional diversity.

Abstract:
Artemisia cina is a wild herbaceous plant that has secondary metabolites as a source of antioxidants. The addition of mycorrhizal species Glomus mosseae can increase the antioxidant activity of plants Artemisia cina. This study aims to determine the effect of mycorrhizal Glomus mosseae on the growth and content of antioxidant compounds in Artemisia cina. The study used a completely randomized design (CRD), with four levels of treatment, namely: media without G. mosseae (control), media with G. mosseae 5,10 and 15 g with 5 replications for each treatment. Parameters observed were plant height, number of leaves, 5th leaf length and width, wet and dry weight, root length, percentage of mycorrhizal colonization, chlorophyll content, carotenoids, flavonoids, phenols were also observed. Antioxidant activity was determined by the DPPH method. The results showed that the treatment Glomus mosseae with a dose of 15 g was significantly different from the control on plant growth parameters, number of leaves, root length, wet weight and dry weight of plants, and percentage of mycorrhizal colonization in plants. Treatment of Glomus mosseae 15 g on the test results of antioxidant compounds also showed the highest content of chlorophyll, carotenoids, phenols and flavonoids from the statistical test results found in the 15 g treatment, respectively, namely 6,405 g/ml; 0.766 g/ml; 70.9 g/ml; and 335 g/ml had a significant difference to the control treatment. While the results of the antioxidant activity test using the DPPH method showed that the control treatment had the highest antioxidant activity with an ICvalue50 of 9,494 g/ml. The results showed that the mycorrhizal species of G. mosseae increased the growth and content of antioxidant compounds inplants A. cina.

Abstract:
Abstract. Mosses, as major components of later successional biological soil crusts (biocrusts), play many critical roles in arid and semiarid ecosystems. Recently, some species of desiccation-tolerant mosses have been artificially cultured with the aim of accelerating the recovery of biocrusts. Revealing the factors that influence the vegetative propagation of mosses, which is an important reproductive mode of mosses in dry habitats, will benefit the restoration of moss crusts. In this study, three air-dried desiccation-tolerant mosses (Barbula unguiculata, Didymodon vinealis, and Didymodon tectorum) were hermetically sealed and stored at five temperature levels (0, 4, 17, 25, and 30 °C) for 40 days. Then, the vegetative propagation and physiological characteristics of the three mosses were investigated to determine the influence of storage temperature on the vegetative propagation of desiccation-tolerant mosses and the mechanism. The results showed that the vegetative propagation of the three mosses varied with temperature. The most variation in vegetative propagation among storage temperatures was observed in D. tectorum, followed by the variation observed in B. unguiculata. In contrast, no significant difference in propagation among temperatures was found in D. vinealis. The regenerative capacity of the three mosses increased with increasing temperature from 0 to 17 °C, accompanied by a decrease in malondialdehyde (MDA) content, and decreased thereafter. As the temperature increased, the chlorophyll and soluble protein contents increased in B. unguiculata but decreased in D. vinealis and D. tectorum. As to storage, the MDA and soluble sugar contents increased after storage. The MDA content of the three mosses increased at each of the investigated temperatures by more than 50 % from the initial values, and the soluble sugar content became higher than before in the three mosses. The integrity of cells and cell membranes is likely the most important factor influencing the vegetative propagation of desiccation-tolerant mosses. A 40-day storage period caused cell injury. Our results suggest that storage temperature can enhance or suppress such injury and change the regenerative capacity of the three mosses. The data indicate that the suitable storage temperature is 4 °C for B. unguiculata and 17 °C for both D. vinealis and D. tectorum.

The present paper represents the positive role of Arbuscular Mycorrhizal (AM) fungi as biofertilizers in strawberry. Experiments were carried out to assess the effectiveness of Trichoderma viride and AM fungi (Glomus mosseae and Acaulospora laevis) alone or in combination, on the growth and biomass production of strawberry. After 120 days, dual inoculation of A. laevis + T. viride showed maximum increase in plant height (30.5±0.3), fresh shoot weight (10.16±0.20), dry shoot weight (2.82±0.02), fresh root weight (6.70±0.10), total chlorophyll (0.841±0.05) and phosphorus content in root (1.13±0.02) as compared to control. However root colonization and AM spore number were maximum in G. mosseae + A. lavies (90.76±1.32) and in G. mosseae (211.16±2.56) respectively as compared to uninoculated plants. Triple inoculation of G. mosseae + A. laevis + T. viride (12.33± 057) was effective in increasing the leaf area.

Abstract:
A pot experiment was conducted to evaluate the response of selected species of mycorrhizae for root colonization and phosphorus uptake by maize in an alluvial soil. Of all the species of mycorrhizae taken under consideration, Glomus mosseae was found to perform better in terms of root colonization, number of spores, grain yield and phosphorus uptake. The maximum plant height (28.5 cm), shoot dry weight (19.45 g plant-1) and root dry weight (4.77 g plant-1) was also found with the application of G. mosseae. Its application significantly increased the root dry weight by 99.58 and 72.82% over application of G. intraradices and control respectively, and was at par with the application of G. coronatum and Gigaspora decipiens. Application of G. decipiens reported the highest bacterial (39.11 cfu g-1 soil) and fungal count (30.68 cfu g-1 soil) that was found to be at par with application of G. mosseae. Application of G. mosseae significantly increased the actinomycetes population by 44.71 and 55.97% over application of a local mycorrhizal strain and control. Maximum dehydrogenase activity (56.00 g-1 TPF g-1 24 h-1) and acid phosphatase activity (0.299 mg PNP g-1 h-1) and was also observed with application of G. mosseae, which in turn resulted in higher yield which was 27.28%, 28.52%, 9.35 and 11.7% more than G. intraradices, G. coronatum, G. decipiens and the local species respectively. G. mosseae inoculation proved to be effective in modifying the soil microbe population and community structure and also in enhancing the soil enzymatic activities and phosphorus uptake of the crop.

Abstract:
The application of treatment T3 (Glomus mosseae + 100 % RDF NK) produced significantly more root volume by 72.60 %, 17.80 %, 12.25 %, 14.13 % over the application of treatment T1 (Control), treatment T5 (Glomus coronatum+ 100 % RDF NK), T6 (Gigasporadecipein + 100 % RDF NK) and T7 (BAU AM-1(Glomus sp + 100 % RDF NK), respectively. Similar trend shows at harvesting stage, here the maximum root volume (23c.c) was recorded by the application of T3 (Glomus mosseae + 100 % RDF NK). Maximum AM colonization and spore count was observed at panicle initiation stage with the application of treatment T3 (Glomus mosseae + 100 % RDF NK). This treatment also gave maximum dehydrogenase activity (55.86 µg TPF g-1 24 hr-1), acid phosphatase activity (0.299 mg PNP g-1 hr-1) and alkaline phosphatase activity (0.54 mg PNP g-1 hr-1) at panicle initiation stage. Application of treatment T3 (Glomus mosseae + 100 % RDF NK) significantly increased DTPA extractable Zn in soil and Zn content in plant when compared with all the treatments except treatment T6 (Gigasporadecipien+ 100 % RDF NK). The maximum zinc uptake (0.056 mg pot-1) by grain was recorded under treatment T3 (Glomus mosseae + 100 % RDF NK) followed by application of treatment T6 (Gigasporadecipien + 100 % N and K). Highest grain yield (14.08 g pot-1) was found with the treatment T3 (Glomus mosseae + 100 % RDF NK). As evident from the results, the AM fungal inoculation can effectively modify the soil microbe population and community structure by increasing the soil enzymatic activities and significantly increased the zinc uptake by grain in direct seeded rice (DSR).

Abstract:
Internal specialized conducting tissues, if present, are restricted to the gametophytic generation in liverworts while they may occur in both generations in mosses. Conducting tissues are unknown in the anthocerotes. Water–conducting cells (WCCs) with walls perforated by plasmodesma–derived pores occur in the Calobryales and Pallaviciniaceae (Metzgeriales) among liverworts and in Takakia among mosses. Imperforate WCCs (hydroids) are present in bryoid mosses. A polarized cytoplasmic organization and a distinctive axial system of microtubules is present in the highly specialized food–conducting cells of polytrichaceous mosses (leptoids) and in less specialized parenchyma cells of the leafy stem and seta in other mosses including Sphagnum . A similar organization, suggested to reflect specialization in long–distance symplasmic transport of nutrients, also occurs in other parts of the plant in mosses, including rhizoids and caulonemata, and may be observed in thallus parenchyma cells of liverworts. Perforate WCCs in the Calobryales, Metzgeriales and Takakia , and hydroids in bryoid mosses, probably evolved independently. Because of fundamental differences in developmental design, homology of any of these cells with tracheids is highly unlikely. Likewise, putative food–conducting of bryophytes present highly distinctive characteristics and cannot be considered homologous with the sieve cells of tracheophytes.

Abstract:
Citrus is a salt-sensitive plant. In the present study, the salt stress ameliorating the effect of arbuscular mycorrhizal fungi through antioxidant defense systems was reported. Three-month-old trifoliate orange (Poncirus trifoliata) seedlings colonized by Glomus mosseae or G. versiforme were irrigated with 0 and 100 mmol NaCl solutions. After 49 days of salinity, mycorrhizal structures were obviously restrained by salt stress. Mycorrhizal inoculation especially G. mosseae significantly alleviated the growth reduction of salinity. There were notably lower malondialdehyde and hydrogen peroxide contents in the leaves of mycorrhizal seedlings than in non-mycorrhizal ones. Mycorrhizal seedlings recorded notably greater activity of catalase and contents of ascorbate, soluble protein and glutathione under salinity or non-salinity conditions. The seedlings colonized by G. mosseae showed significantly higher antioxidant defense systems response to salinity than by G. versiforme. Our data demonstrate that mycorrhizal (especially G. mosseae) citrus seedlings exhibited greater efficient antioxidant defense systems, which provide better protection against salt damage.

The effect of root exudates from non-mycorrhizal and mycorrhizal cucumber (Cucumis sativus L.) plants colonized by one of three arbuscular mycorrhizal fungi (Gigaspora rosea Nicolson & Schenck, Glomus intraradices Smith & Schenck, or Glomus mosseae (Nicolson & Gerdemann) Gerd. & Trappe) on hyphal growth of Gi. rosea and G. intraradices in axenic culture and on root colonization by G. mosseae in soil was investigated. Root exudates from non-mycorrhizal cucumber plants clearly stimulated hyphal growth, whereas root exudates from all mycorrhizal cucumber plants tested showed no stimulation of the hyphal growth of Gi. rosea and only a slight stimulation of the hyphal growth of G. intraradices. Moreover, root exudates from all mycorrhizal cucumber plants inhibited root colonization by G. mosseae compared with the water-treated controls. These results suggest that plants colonized by AM fungi regulate further mycorrhization via their root exudates.Key words: Glomales, Gigaspora rosea, Glomus intraradices, Glomus mosseae, root exudates, regulation.

Abstract:
Effects of the arbuscular mycorrhizal (AM) fungi, Glomus mosseae, G. intraradices, and G. etunicatum, on plant growth, antioxidant content, osmoregulation, and nutrition were investigated in ‘Premier’ blueberry (Vaccinium ashei) plants exposed to low-temperature stress. Low temperature decreased mycorrhizal colonization, growth, levels of leaf soluble sugar, ascorbic acid (ASA) and root viability. However, at low temperatures, levels of leaf superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) were found to increase, accompanied by increases in levels of ASA, malondialdehyde (MDA), and proline. G. mosseae especially, significantly increased levels of SOD, POD, CAT and ASA, but decreased levels of MDA in plants. AM-inoculated plants had higher contents of proline, soluble sugar, phosphorus, potassium, calcium and magnesium than non-AM-inoculated plants, especially in the G. mosseae-inoculated plants. These results indicate that G. mosseae has the potential to enhance resistance of ‘Premier’ blueberry plants against low-temperature stress through improving antioxidant content, osmotic adjustment and mineral nutrition.

Abstract:
Mosses or bryophytes, belonging to the lower plants, can grow on higher plants (as epiphyte), stone (epilytic), bark (corticolus), and the surface of the soil. One of the important places in East Java and having a variety of potential mosses is Tumpak Sewu Waterfall. In this place, moss grows well because of the condition of the nature, humidity, and abundant air. This study aimed to identify and calculate the population of mosses at Tumpak Sewu Waterfall, Lumajang, East Java. The research sampling has been performed along hiking trip, riverside and tourist area of Tumpak Sewu Waterfall. Quadratic method with grid lines with a plot size of 1x1 m² on the right and left sides of the river was used to collect and calculate mosses population. Mosses identification was performed using mosses identification key. The population data obtained from this study were analyzed by calculating Frequency, Dominancy and Important Value Index (IVI). This study found 7 species of mosses in which 3 species belong to Family Marcahntiaceae, 2 species belongs to Bryaceae and 1 species belongs to Pottiaceae and Anthocerotaceae, respectively. The highest of IVI value is specimen K2, corresponds to Pohlia flexuosa W.J. Hooker, with 78.178%, and the lowest of IVI value is specimen K6, corresponds to Marchantia sp. with 4.524%. It can be concluded that Tumpak Sewu Waterfall has diversity for mosses that could be useful to conserve Indonesian natural resources especially lower plants.

Abstract:
Continuous cropping in soybean is increasingly practiced in Heilongjiang Province, leading to substantial yield reductions and quality degradation. Arbuscular mycorrhizal fungi (AMF) are soil microorganisms that form mutualistic interactions with plant roots and can restore the plant rhizosphere microenvironment. In this study, two soybean lines (HN48 and HN66) were chosen as experimental materials, which were planted in different years of continuous cropping soybean soils and were inoculated or not with Funneliformis mosseae in potted-experiments. Ultimately, analysis of root tissue metabolome and root exudates, soil physicochemical properties, plant biomass, as well as rhizosphere soil properties in different experimental treatments, inoculated or not with F. mosseae, was performed. Experimental results showed that: (a) The disease index of soybean root rot was significantly lower in the treatment group than in the control group, and there were differences in disease index and the resistance effect of F. mosseae between the two cultivars; (b) compared with the control, the root tissue metabolome and root exudates remained unchanged, but there were changes in the relative amounts in the treatment group, and the abundant metabolites differed by soybean cultivar; (c) soybean biomass was significantly higher in the treatment group than in the control group, and the effect of F. mosseae on biomass differed with respect to the soybean cultivar; and (d) there were differences in the physiochemical indexes of soybean rhizosphere soil between the treatment and control groups, and the repairing effect of F. mosseae differed between the two cultivars. Therefore, F. mosseae can increase the biomass of continuously cropped soybean, improve the physicochemical properties of the rhizosphere soil, regulate the root metabolite profiles, and alleviate barriers to continuous cropping in potted-experiments of soybean.

I would like to discuss George Mosse's excellent and stimulating book, Fallen soldiers, mainly from a French point of view, and to comment upon some issues about the political and moral consequences of the First World War upon French and German societies.The core of the question is Mosse's assumption of a strong relationship between the war experience and the emergence of nazism in Germany. Hence, I shall examine first the reasons why, in Mosse's argument, Hitlerism appears as a consequence of the war. Then I ask why such an evolution did not happen in France, although the war experience was quite similar in the two countries.

The ecological characteristics of sphagnum mosses are discussed. A detailed investigation of ecotopes and plant communities dominated by sphagnum mosses was conducted. The study of tree stands, herb and moss layers, soils and analysis of Lake Germanovskoe hydro-chemical characteristics were carried out to define the conditions of Sphagnum habitats. Different sphagnum mosses dominate in ecotopes with various regime of moisture. The swamped part of Lake Germanovskoe catchment area is determined as having mesotrophic characteristics. Аnalysis of the ecological characteristics of sphagnum mosses shows the same result.

Abstract:
The effects of an arbuscular mycorrhizal fungus, Glomus mosseae, on plant growth, soil aggregate stability, and rhizosphere carbon pools of young Citrus junos seedings were investigated with potted experiment in greenhouse. After three months of mycorrhizal inoculation, root colonization was 54.25%. Inoculation with G. mosseae significantly promoted plant height, stem diameter, leaf number, and shoot and root fresh weights. Colonization by G. mosseae significantly increased soil aggregate stability of the citrus rhizosphere through increase of mean weight diameter. G. mosseae could release a specific glycoprotein viz. glomalin into the rhizosphere as glomalin-related soil protein (GRSP). Meanwhile, mycorrhizal colonization was significantly positively correlated with two GRSP fractions. In stabilization of aggregate stability, in GRSP fractions only easy extractable -GRSP might contribute the role. The mycorrhizal symbiosis could increase soil organic carbon, hot-water extractable carbohydrates, and hydrolyzed carbohydrates concentrations, but the differences were not significant. Combined with the correlation analysis, it suggests that GRPS did not significantly regulate rhizospheric carbon pools, due to the short treated time (only 3 months).

In the present investigation, the contributions of two indigenous arbuscular mycorrhizal fungi (Glomus mosseae and Acaulospora laevis), along with Trichoderma viride and Bradyrhizobium japonicum on growth parameters of Soybean, Glycine max (L.) Merrill were investigated. The results obtained indicated the dependence of soybean on mycorrhizal symbiosis. The different growth parameters increased significantly after 120 days of inoculation in comparison to control. Among all the growth parameters studied, plant height (162±3.34), fresh shoot weight (31.26±1.45), dry shoot weight (3.52±0.05), fresh root weight (4.07±0.56), dry root weight (1.03±0.03), root length (49.0±4.47) and leaf area (32.58±1.70) were highest in the combination of G. mosseae + A. laevis + T. viride + B. japonicum but arbuscular mycorrhizal (AM) spore number (95.2±3.19) and percent mycorrhizal root colonization (93.26±3.96) were maximum in single inoculation of G. mosseae. Second most effective results were observed in the plants treated with G. mosseae alone. Thus the presence of arbuscular mycorrhizal fungi (AMF) and other bioinoculants in rhizosphere of soybean had positive effect on the different growth parameters.

Abstract:
There is some debate about the potential survival of Pseudomonas fluorescens at temperatures above 37 °C and its consequences for infectious potential, owing to the heterogeneity of clinical strains. Seven clinical strains growing at 37 °C or more were submitted for polyphasic identification; 2 were identified as Pseudomonas mosselii and 4 were precisely characterized as P. fluorescens bv. I or II. The binding indexes on glial cells of the strains identified as P. fluorescens bv. I and P. mosselii were compared with that of a reference psychrotrophic strain, P. fluorescens MF37 (bv. V). Clinical P. fluorescens had a similar adherence potential range than strain MF37. Conversely, the binding indexes for P. mosselii strains were 3 times greater than that for strain MF37. These data, and those obtained by comparing the cytotoxic activities of P. fluorescens clinical strains, suggest the existence of different virulence mechanisms, leading either to a low infectious form or to a microorganism with cytotoxic activity in the same range as that of P. mosselii or even Pseudomonas aeruginosa .

Full text
Abstract:
The nucleotide variation of a noncoding region between the atpB and rbcL genes of the chloroplast genome was used to estimate the phylogeny of 11 species of true mosses (subclass Bryidae). The A+T rich (82.6%) spacer sequence is conserved with 48% of bases showing no variation between the ingroup and outgroup. Rooted at liverworts, Marchantia and Bazzania, the monophyly of true mosses was supported cladistically and statistically. A nonparametric Wilcoxon Signed-Ranks test Ts statistic for testing the taxonomic congruence showed no significant differences between gene trees and organism trees as well as between parsimony trees and neighbor-joining trees. The reconstructed phylogeny based on the atpB-rbcL spacer sequences indicated the validity of the division of acrocarpous and pleurocarpous mosses. The size of the chloroplast spacer in mosses fits into an evolutionary trend of increasing spacer length from liverworts through ferns to seed plants. According to the relative rate tests, the hypothesis of a molecular clock was supported in all species except for Thuidium, which evolved relatively fast. The evolutionary rate of the chloroplast DNA spacer in mosses was estimated to be (1.12 ± 0.019) × 10-10 nucleotides per site per year, which is close to the nonsynonymous substitution rates of the rbcL gene in the vascular plants. The constrained molecular evolution (total nucleotide substitutions, K approximately 0.0248) of the chloroplast DNA spacer is consistent with the slow evolution in morphological traits of mosses. Based on the calibrated evolutionary rate, the time of the divergence of true mosses was estimated to have been as early as 220 million years ago.Key words: atpB-rbcL noncoding spacer, chloroplast DNA, gene tree, molecular evolution, molecular clock, mosses, phylogeny.

Abstract:
The best productions of mycorrhizal roots from cereals in sand culture treated with four ratios of NO3 to NH4 in three concentrations of a balanced nutrient solution (Hewitt's) were (i) maize – Glomus mosseae: 30–50% colonization and 120–150 m of colonized root per plant from full-strength solution with 95–100% NO3-N; (ii) wheat – G. mosseae: 80–90% colonization from 0.1-strength solution and 40–50 m from 0.25-strength solution with 50–100% NO3-N; (iii) maize – Glomus fasciculatum: 70% and 120 m from 0.25-strength solution with 50% NO3-N; and (iv) wheat – G. fasciculatum: 25 – 30% and 10–15 m from 0.1-strength solution with 50 – 100% NH4-N. The highest nutrient strengths eliminated colonization in wheat or reduced numbers of vesicles and arbuscules. Vesicles were predominant at the lowest nutrient strengths. Ammonium reduced mycorrhizosphere pH, colonization, and sporocarp and ectocarpic spore production. Multiple regression showed best colonization with (i) maize – G. mosseae, pH > 7.4, and best vesicle and arbuscule development with root P < 0.1%; (ii) wheat – G. mosseae, pH 7.2–7.7, root P < 0.055%, and root N > 1.07%; (iii) maize – G. fasciculatum, pH 5.6–6.2, root P < 0.08%, and root N > 1.44%; and (iv) wheat – G. fasciculatum, pH 6.7–6.9. Maize – G. mosseae was grown by the nutrient film technique in 0.1-strength solution with NO3 and rock phosphate. Improving the production of the inoculum from hydroponic culture of cereals is discussed.

Abstract. Sphagnum peatlands are important ecosystems in the methane cycle. Methanotrophs living in and on the Sphagnum mosses are able to act as a methane filter and thereby reduce methane emissions. We investigated in situ methane concentrations and the corresponding activity and diversity of methanotrophs in different Sphagnum dominated bog microhabitats. In contrast to the Northern Hemisphere peat ecosystems the temperate South American peat bogs are dominated by one moss species; Sphagnum magellanicum. This permitted a species-independent comparison of the different bog microhabitats. Potential methane oxidizing activity was found in all Sphagnum mosses sampled and a positive correlation was found between activity and in situ methane concentrations. Substantial methane oxidation activity (23 μmol CH4 gDW−1 day−1) was found in pool mosses and could be correlated with higher in situ methane concentrations (>35 μmol CH4 l−1 pore water). Little methanotrophic activity (<0.5 μmol CH4 gDW−1 day−1) was observed in living Sphagnum mosses from lawns and hummocks. Methane oxidation activity was relatively high (>4 μmol CH4 gDW−1 day−1) in Sphagnum litter situated at depths around the water levels and rich in methane. The total bacterial community was studied using 16S rRNA gene sequencing and the methanotrophic communities were studied using a pmoA microarray and a complementary pmoA clone library. The methanotrophic diversity was similar in the different habitats of this study and surprisingly comparable to the methanotrophic diversity found in peat mosses from the Northern Hemisphere. The pmoA microarray data indicated that both alpha- and gammaproteobacterial methanotrophs were present in all Sphagnum mosses, even in those mosses with a low initial methane oxidation activity. Prolonged incubation of Sphagnum mosses from lawn and hummock with methane revealed that the methanotrophic community present was viable and showed an increased activity within 15 days. The high abundance of methanotrophic Methylocystis species in the most active mosses suggests that these might be responsible for the bulk of methane oxidation.

The pmoA microarray data indicated that both alpha- and gammaproteobacterial methanotrophs were present in all Sphagnum mosses, even in those mosses with a low initial methane oxidation activity. Prolonged incubation of Sphagnum mosses from lawn and hummock with methane revealed that the methanotrophic community present was viable and showed an increased activity within 15 days. The high abundance of methanotrophic Methylocystis species in the most active mosses suggests that these might be responsible for the bulk of methane oxidation.
