Hatimi A, Tahrouch S, Bouizgarne B. 2018. Effect of symbiotic association of rhizobia and endomycorrhizae from Moroccan arid littoral dunes on Acacia cyanophylla tolerance to drought. Asian J For 2: 39-45. The research on behavior of A. cyanophylla Lindl plants associated with a symbiotic indigenous endomycorrhizal fungi M, and three rhizobia isolates: two low growing isolate R1 (Bradyrhizobium sp. RCM6), and R2 (Bradyrhizobium sp. RLC3) and a fast-growing isolates R3 (Rhizobium sp. S21), originated from coastal dunes of the Souss-Massa region in drought stress conditions, was investigated in greenhouse. Results have clearly shown that the growth and nutrition of seedlings of A. cyanophylla were drastically affected after two months in drought stress conditions. However, inoculation of the symbiotic microorganisms either alone (treatments M, RMC6, R2 or R3) or as inoculums consisting of combination of the rhizobia with the endomycorrhiza (treatments MR1, MR2 or MR3) resulted in enhanced tolerance of A. cyanophylla seedlings to drought stress. At 100% of field capacity (fc), all treatments showed a significant improvement of plant growth compared to non-inoculated plants in stress conditions. In addition, we have shown that Bradyrhizobium RCM6 (R1) holds a high efficiency to improve the growth and nutrition of the host plant. Indeed, higher number of nodules/plant and higher amount of total nitrogen were recorded in the seedlings inoculated with Bradyrhizobium sp. RCM6 in comparison with plants inoculated with the two other rhizobia Bradyrhizobium sp. RLC3 (R2) and Rhizobium sp. S21 (R3), and control plants. Dual inoculation with each of the three rhizobia and the endomycorrhizal complex (M) led to higher water content (W.C) and relative water content (RWC) and a significant increase in Phosphorus content of the aerial part. While positive effects were recorded for Phosphorus, no such effects were recorded for nitrogen. However, the overall results showed the importance of the use of microorganisms in the dune coastal environment particularly adequate tripartite association: rhizobia Endomycorrhizes-A. cyanophylla in enhancing tolerance to drought stress.

Abstract:
Although mycorrhizal associations are commonly found on roots of most plant species, little is known about the presence or absence of mycorrhizae in arctic regions. In the Canadian High Arctic, roots of 55 herbaceous and woody plant species were examined for mycorrhizae during the summers of 1987 and 1988 on Devon Island, N.W.T. Ectomycorrhizal associations were found on roots of Salix arctica, Dryas integrifolia, and Potentilla hyparctica; ericoid mycorrhizae formed on Cassiope tetragona and Vaccinium uliginosum. Ectomycorrhizal roots were often covered with black hyphae resembling the fungus Cenococcum geophilum; sclerotia characteristic of this fungus were found in soil extracts. Plants expected to have endomycorrhizal associations were apparently nonmycorrhizal in the traditional sense, since no arbuscules, vesicles, or pelotons were found on any roots during two field seasons. Although extensive fungal hyphae were often present on and within roots, these hyphae could not be conclusively identified as endomycorrhizal. Some dark, septate hyphae were present; their function, although unknown, may be beneficial to the host. In a series of greenhouse bioassays using arctic soils, no endomycorrhizal associations developed on test plants. Spores of vesicular–arbuscular fungi were not found in soil extracts. Thus in this survey, only ectomycorrhizal associations were observed, suggesting that the cold, dry winter and cold, wet summer climates in this area of the High Arctic severely limit formation of endomycorrhizae. Key words: roots, fungi, ectomycorrhizae, endomycorrhizae, arctic.

Abstract:
Sengon (Paraserianthes falcataria (L.) Nielsen) is a tree species commonly planted in community forests and managed using an agroforestry system. In order to grow a high-quality sengon tree, high-quality seeds are essentials. In addition, providing biofertilizers and organic fertilizers during the nursery phase is necessary. This study aimed to determine the effect of Trichoderma spp., endomycorrhizae, and compost fertilizer combination on the growth of sengon (Paraserianthes falcataria (L.) Nielsen) seeds and to determine the optimum ratio to increase the growth of sengon seeds. The research was performed in the Plant Taxonomy Laboratory (Mycology) and Unda Anyar Watershed and Protected Forest Management Office in Bali. The research was performed with six treatments, namely: A (sterile or untreated soil), B (sterile soil and 10 g of compost), C (10 ml Trichoderma spp.), D (10 ml Trichoderma spp., 100 endomycorrhizal spores, and 10 g compost), E (10 ml Trichoderma spp., 150 endomycorrhizal spores, and 10 g compost), and F (10 ml Trichoderma spp., 200 endomycorrhizal spores, and 10 g compost). This study consisted of five groups with three sub-unit plants. The results showed that the combination of Trichoderma spp., endomycorrhizae, and compost fertilizer significantly increased plant height, amount of stem branches, fresh weight and dry weight of plant, and dry weight of root compared to control. However, the effect on the root fresh weight was not significant. A combination of 10 ml Trichoderma spp., 150 endomycorrhizal spores, and 10 g of compost fertilizer was the most optimal and effective in increasing the growth of sengon seeds. Keywords: mycorrhiza, sengon seedlings, woody plants

Abstract:
Response of Growth and Yield of Sweet Corn to Dosage of Spores of Indigenous Endomycorrhizae. Endomycorrhizae is a form of mutualism association between fungi (myces) and roots (rhiza) of higher plants. The symbiotic relationship that occurs at the roots is mutually beneficial. Plants can provide carbon organic compounds for fungal growth, whereas fungi benefit plants by increasing nutrient uptake, water, producing enzymes, antibiotics and other compounds given to host plants. The study was conducted to know the effect of dosage of spores of endomycorrhizae indigenous to growth and yield of sweet corn. The experiments were carried out in laboratories and greenhouses. The design used was a completely randomized design with one factor namely the dose of spores of endomycorrhizae consisting of three levels, i.e. D0 = without inoculation of endomycorrhizae, D1 = 75 spores of endomycorrhizae/plant, and D2 = 150 spores of endomycorrhizae/plants. The results showed that dose of spores of endomycorrhizae treatment had a significant effect on growth and yield of sweet corn. The highest fresh weight of cob was obtained at a dose of 150 spores/plant, namely 181.33 g / plant. Based on the results of this study, it is necessary to conduct research in the field using a dose of 150 spores of endomycorrhizae per plant.

Abstract:
Response of Salak Seedling (Salacca edulis L.) Growth to Endomycorrhizal Spore Doses on Volcanic Sand and Sea Sand Carrier. Endomycorrhizae has several benefits, such as increase water absorption and nutrients of plant, protect plants from root pathogens and toxic substances, play a role in improving soil structure, and increase nutrient solubility. This study aimed to determine the growth response of salak seedlings to doses of endomycorrhizal spores in media carrying volcanic sand and sea sand. This study used a factorial randomized block design (RBD) with two treatments i.e. the number of spores and the type of carriers media. The results showed no significant interaction between the number of mycorrhizal spores doses with the carrier media on all observed variables. Spores doses significantly affected stem diameter and root mycorrhizal infection variables. The highest stem diameter was achieved at the dose of 75 spores that was 1.60 cm which was significantly different from control (1.28 cm), whereas the highest root infection was obtained at the dose of 225 spores (92.50%) which significantly higher than control (36.25%). At the observation of 4 MAP (month after planting) the highest root infection was obtained at the dose of 150 spores (82.50%) compared to control (10.00%). Volcanic sand carrier media produced the highest plant dry weight (3.59 g) which was significantly different to the sea sand (2.43 g).

Abstract:
Growth of strawberry (Fragaria ×ananassa Duch. `Sweetheart') seedlings inoculated with six spore levels ranging from 0 to 12,000 spores/plant of the mycorrhizal fungi Glomus intraradices Schenck and Smith was studied in the greenhouse and with greenhouse plants subsequently moved to the field. Plant height, leaf area, and number of leaves increased significantly with inoculum spore densities ranging from 750 to 12,000 spores/plant in relation to control plants in the greenhouse and field. In the greenhouse, there was a linear relationship between percent infection and spore density, although the relationship was cubic in the field. In the field study, control plants were infected with indigenous mycorrhizae, but inoculated plants produced more runners than the control plants, and foliar Cu and Ca increased linearly with increased spore density. Inoculated plants contained significantly more dry matter than the controls. For inoculated plants, root dry weight increased linearly with increased spore density. We conclude that a minimum spore density of 750 spores/plant is sufficient for a positive growth response.

Abstract:
The genus Bambusa Schreb. which belongs to the Poaceae family is commonly present in north-eastern region of India. A survey was undertaken in three villages viz. Tilikiaam, Maoutgaon and Nathgaon of Jorhat district, Assam, North-east India, where natural populations of Bambusa species were observed. Four bamboo species i.e. Bambusa bambos (L.) Voss, B. tulda Roxb., B. pallida Munro and B. nutans Wall. ex. Munro were found locally economically important and the rhizospheric soil and root samples were collected for screening of dark septate endophytes (DSE) as well as arbuscular mycorrhizal (AM) colonization. Quantitative analysis of root samples showed the presences of all the three types of endomycorrhizal root infection/colonization namely hyphal, vesicular and arbuscular. Beside this, the dark septate endophytic infections were also observed in all the bamboo species. The cent-percent endomycorrhizal (hyphal and vesicular) and DSE hyphal infections were reported in roots of all the bamboo species respectively. There were variations observed in arbuscular infection in B. nutans and B. bambos (100%), B. pallida (90%) and least in B. tulda (70%). Qualitative analysis revealed that the Endomycorrhizae found in the rhizospheric soil predominantly belongs to five genera viz. Glomus, Acaulospora, Gigaspora, Scutellospora and Entrophospora. The genus Glomus, is the most dominant, with 17 species (61%), Acaulospora with 7 species (25%), Entrophospora with 2 species (7%), Scutellospora (3.5%) and Gigaspora (3.5%) with 1 species each. Distribution of AM fungi were highest in B. bamboos (67.7%) followed by B. pallida (19.4%), B. tulda (11.1%) and least in B. nutans (2.8%). Bamboo resources have been considerably declining due to exploitation, shifting cultivation, gregarious flowering and extensive forest fires from the natural habitats. Therefore, further microbial based applied researches should be undertaken to protect the dwindling natural bamboo resources and considering AMF bioinoculants in future management practices in order to maintain diminishing ecosystems.

Abstract:
Both lettuce and pepper crops are routinely grown as transplants in Quebec. Previous research has shown that both of these plants respond well to endomycorrhizae with a resulting improvement in plant growth and yield. Although many studies have been conducted on endomycorrhizal inoculation of transplants most were looking at the end result, i.e. yields, and did not focus on changes occurring at the transplant stage. This series of experiments was conducted to look at the effect of inoculation at the transplant stage. Lettuce (Lactuca sativa cv. Parris Island Cos) and pepper (Capsicum annuum cv. Hybrid Bell Boy) were inoculated with Glomus intraradix Schenck & Smith and Glomus versiforme (Karst.) Berch. Experiments involved testing the effect of different growing media, different container volumes and different light sources on the growth of endomycorrhizal lettuce and pepper transplants. In all experiments the amount of growth enhancement due to endomycorrhizal inoculation was low or negligible. Colonization rates were generally low, probably due to low light levels. Transplants grown in larger volume containers were generally larger than those grown in smaller containers. The transplants grown in the soil and compost based media were larger than those transplants grown in the artificial media. Growth of lettuce and pepper transplants was affected differently depending on the light source used. Some interactions between the light source and the endomycorrhizal treatments was observed.

Abstract:
Inoculation of Parthenium argentatum (guayule) with an endomycorrhizal fungus (Glomus intraradices) increased the growth of guayule in saline and non-saline soils low in available phosphorus. Addition of 100 ug/g of P as Ca(H2PO4)2 to soils low in available phosphorus was as efficient as G. intraradices in stimulating the growth of guayule. The concentrations and total plant accumulations of minerals within guayule shoots varied depending on growth of the plants and the minerals assayed. In most cases, the concentrations of Cu, Zn, Mn, Na and Cl increased in the shoot tissues of guayule grown in soils which contained added NaCl. Generally, addition of phosphorus to the soil resulted in decreased concentrations of Cu and Zn and increased concentrations of PO4 in guayule shoots. The total accumulations of minerals by guayule was directly influenced by the biomass of plants. Increased biomass of plants generally resulted in increased total accumulations of the minerals assayed. The influence of mycorrhizae on the accumulations of minerals by guayule grown in a saline soil was evaluated by comparing nonmycorrhizal plants with the same biomass and phosphorus nutrition as mycorrhizal plants. Mycorrhizae increased the concentrations and total plant accumulations of Zn and decreased the content of Cl within guayule shoots. Colonization of guayule roots by G. intraradices was not affected by addition of P to the soil. Addition of NaCl to the soil decreased the formation of arbuscules and vesicles within roots and increased the incidence in which no fungal structures were seen. The combination of P and NaCl added to soil had a synergistic effect on the mycorrhizae of guayule. Addition of both P and NaCl to soil reduced the occurrence of hyphae, arbuscules and vesicles within roots and decreased the overall infection of guayule roots by G. intraradices.

Abstract:
Onions are highly responsive to endomycorrhizae and improved plant growth is among the benefits associated with this symbiosis, particularly in low phosphorus soils. Although this crop is grown extensively in organic soils, few studies have been conducted on these. Onion plants (Allium cepa L. cv. Norstar) were inoculated with Glomus aggregatum Schenck & Smith, Glomus clarum Nicolson & Schenck, Glomus fasciculatum Gerdemann & Trappe, Glomus intraradix Schenck & Smith and Glomus versiforme (Karst.) Berch and grown in the field and under controlled conditions to evaluate their efficiency in newly reclaimed organic soil of low P fertility. Three species were selected to evaluate the effects of introduced endomycorrhizal fungi effects and P fertilization (equivalent to 0, 24 and 48 kg P ha$ sp{-1}$) on the growth and mineral nutrition of onion plants.
Introducing endomycorrhizal fungi in non-sterile soil did not affect the growth and mineral nutrition of onion. Crop maturity was advanced when plants were inoculated, however. Increasing levels of P fertilization did not depress root colonization and onion growth was increased significantly at the highest rate only. These results suggest that higher levels than recommended could be used in this soil. Inoculation in $ gamma$-irradiated (10 kGy, $ sp{60}$Co) soil alleviated excessive Mn absorption by onion plants. Adding P fertilizer depressed growth and root colonization when plants were inoculated with G. clarum and G. intraradix and was related to the low irradiance levels used in this study. G. versiforme appeared to be the most efficient of the introduced species.

Abstract:
The success of reafforestation schemes depends largely on the silvicultural systems employed. An indication of the ecological sensitivity of such practices can be gauged from the extent to which the soils physical, chemical and microbiological properties are altered. Of particular interest is the impact on the vescicular-arbuscular mycorrhizal (VAM) fungi as they play an important role in ensuring that forest trees especially those growing on nutrient deficient soils acquire sufficient mineral nutrients for growth. This study therefore set out to examine the effects of different methods of site preparation (Manual 'recru', mechanical 'recru' and complete clearance) and the subsequent outplanting with Terminalia ivorensis on the VAM population dynamics in the Mbalmayo Forest in Cameroon. Observations made prior to site preparation indicated the presence of an array of 17 VAM fungi belonging to the generas Acaulospora, Glomus, Sclerocystis and Scutellispora. Of the 17 fungi, one, Glomus etunicatum always represented more than 50% of the spore population. The importance of the tree component of the forest vegetation as reservoirs of VAM inocula was evident from, a) the higher number of spores in association with T. superba compared with shrubs and b) the peak in spore density close to T. superba trees (2.5m). Seasonal effects were suspected as many VAM fungi sporulated more profusely in the dry season (February, 1987) compared to the two rainy seasons (August 1987 and August 1988). Site preparation led to a dramatic reduction in spore number with the completely cleared plot losing 65% of its initial spore population. One year after planting, however, mean spore numbers had increased dramatically in all cleared plots, a major cause of the increase being the increase in root densities from the planted T. ivorensis and the invasive ruderal Eupatorium odoratum and pioneer tree Musangacecropioides. In the mechanically and completely cleared plots the sharp rise in spore numbers was mainly by the fungal aggregate G. occultum/A. scrobiculata which sporulated profusely in the presence of the invasive ruderal Eupatorium odoratum. The amounts of infection within the roots of T. ivorensis 1.5 years after planting in the manual and mechanical 'recru' plots were significantly greater than observed within T. ivorensis roots in the completely cleared plot. These differences may be related to the initial drop in spore numbers following site preparation, the disruption of the VAM hyphal networks in soil and/or the increasing dominance of G. occultum/A. scrobiculata, a type believed to be more associated with Eupatorium odoratum and hence possibly less effective on T. ivorensis. The value of the silvicultural procedures that were less destructive appeared to be reflected in tree survival.

Blueberries are temperate fruit species of great economic importance that has stood out in Southern Brazil. The objectives of this study were to evaluate the influence of arbuscular mycorrhizal fungi (AMF) on the production of plantlets of blueberry, as well as isolate and identify these fungi from the orchards in the South - RS. Samples were collected from soil and roots in experimental and commercial of blueberry orchards in the municipalities Pelotas, Morro Redondo and Jaguarão and ecological indexes used as a measure populations in orchards in the study and principal components analysis to assess the physical and chemical soil in relation to the AMF. We identified 18 different morphotypes of spores. The percentages of root colonization with AMF were high, ranging from 40 to 80%. Since the varieties in commercial orchard located in the city of Morro Redondo city were the most colonized in relation to others. The greatest number of spores found in O'Neal in the orchard from Micaela. The relative abundance and the highest Shannon diversity index (H ') and richness (R) were found in the older areas of cultivation, old orchard at Embrapa (EPV) and the commercial orchard in the Morro Redondo city (MR). The relative frequency shows the prevalence of species of the genus Glomus and Acaulospora in all orchards. The dominance evaluated by the Simpson index (Is) showed the same trend as the Shannon diversity and richness. Among the chemical parameters of soil, there was a high correlation of AMF species with varying pH, V (%), P and sand. AMF isolates for the production of seedlings were provided by Bank of species of the Department of Horticulture and Forestry at UFRGS. Were tested four species of AMF (Glomus clarum, Glomus etunicatum, Gigaspora margarita and Scutellospora heterogama) on the production of cultivars Woodard and Bluegem. The AMF would have positive effects in the nursery, particularly Gigaspora margarita which provided better nutrition, and higher biomass of plants growing Woodard and Glomus etunicatum Bluegem for cultivation. The efficiency of the mycorrhizal symbiosis of blueberry cultivars, depends on the interaction specifies AMF X host.
O mirtilo é uma espécie frutífera de clima temperado de grande importância econômica que vem se destacando na região Sul do Brasil. Os objetivos desse trabalho foram avaliar a influência de fungos micorrízicos arbusculares (FMA) na produção de mudas micropropagadas de mirtilo, assim como isolar e identificar esses fungos oriundos dos pomares da região Sul - RS. Foram coletadas amostras de solo e raízes em pomares comerciais e experimentais de mirtilo dos municípios de Pelotas, Morro Redondo e Jaguarão e utilizados índices ecológicos como forma de avaliar as populações nos pomares em estudo e a análise de componentes principais para avaliar os atributos físicos e químicos do solo em relação aos FMAs. Foram identificadas 18 diferentes morfotipos de esporos de FMA. As porcentagens de colonização radicular com FMA foram elevadas, variando de 40 a 80%. Sendo que as variedades localizadas no pomar comercial do município do Morro Redondo foram as mais colonizadas em relação às demais. O maior número de esporos foi encontrado na variedade O‟Neal no pomar comercial da Micaela. A abundância relativa e os maiores índices de diversidade Shannon (H‟) e riqueza (R) foram encontrados nas áreas mais velhas de cultivo, pomar velho experimental da Embrapa (EPV) e do pomar comercial do município Morro Redondo (MR). A frequência relativa demonstra a prevalência de espécies do gênero Glomus e Acaulospora em todos os pomares. A dominância avaliada pelo índice de Simpsom (Is) apresentou a mesma tendência da diversidade de Shannon e da riqueza. Entre os parâmetros químicos do solo, houve uma alta correlação das espécies de FMA com as variáveis pH, V(%), P e areia. Os isolados de FMAs para a produção de mudas foram cedidos pelo banco de espécies do Departamento de Horticultura e Silvicultura da UFRGS. Testaram-se quatro espécies de FMAs (Glomus clarum, Glomus etunicatum e Scutellospora heterogama e Gigaspora margarita) sobre a produção de mudas das cultivares Woodard e Bluegem. Os FMAs proporcionaram efeito positivo na produção das mudas, em especial Gigaspora margarita que proporcionou melhor nutrição e maior incremento na biomassa nas plantas da cultivar Woodard e o Glomus etunicatum para a cultivar Bluegem. A eficiência da simbiose dos FMAs em cultivares de mirtilo, depende da interação especifica FMA X hospedeiro.

Abstract:
Nous avons réalisé une analyse fonctionnelle détaillée du promoteur du gène MtENOD11 au cours des infections endosymbiotiques et en réponse aux signaux spécifiques secretés par Rhizobium appelés facteurs Nod (FNods) qui jouent un rôle clé dans l'établissement de la syymbiose fixatrice d'azote. Nous avons identifié une région promotrice de 257 pb suffisante pour diriger une expression au cours de l'infection par Rhizobium, et de l'association endoymcorhizienne et lors de l'interaction parasitaire avec les nématodes à galles Meloidogyne incognita. Nous avons caractérisé un motif riche en AT requis à la fois pour l'expression associée à l'infection par Rhizobium et par les endomycorhizes, montrant pour la première fois des mécanismes similaires de régulation lors des infections endosymbiotiques raciniares. Nous avons ensuite caractérisé pour la première fois une unité régulatrice originale (appelée NF-box) suffisante pour conférer une expression dépendante des FNods et épiderme-spécifique. Nous avons également démontré qu'au moins trois sites de liaison de facteurs trans sont importants pour cette réponse. Enfin, nous avons initié des approches gènes candidats et un criblage simple hybride chez la levure pour identifier les facteurs trans impliqués dans l'activation de gènes par les Fnods
We have undertaken a detailed functional analysis of Medicago truncatula ENOD11 gene promoter during endosymbiotic infections and in response to specific rhizobial signals known as Nod factors (NFs), which play a key role in the establishment of the N-fixing symbiosis. First, we defined a 257 bp promoter sequence sufficient to direct expression during rhizobial infection, arbuscular endomycorrhizal (AM) fungi association and Meloidogyne incognita parasitic root knot nematode interaction. We characterized an AT-rich motif required for both rhizobial- and mycorrhizal-related infection, thus providing the first direct evidence for similarities in gene regulatory mechanisms during endosymbiotic root colonization. Subsequently, we were able to define a 33 bp novel regulatory unit (named NF-box), sufficient to confer NF-dependent, epidermal-specific expression. We further demonstrated that the NF-box unit comprises at least three adjacent trans-factor binding motifs which are important for this response. Finally, we initiated yeast one-hybrid screening and candidate gene approach to identify trans-factors involved in NF-mediated activation
