The populational floatation of the aphids Aphis spiraecola (Patch, 1914), Aphis gossypii (Glover, 1887), Toxoptera aurantii (Boyer de Foscolombe, 1841) and Toxoptera citricidus (Kirkald, 1907) was studied and related to climate variations from May of 2004 to April of 2005, through the use of Pearsons s Correlation Analysis. The sampling was carried out every two weeks, through Möericke trap. The highest populational densities of A. gossypii occurred in August and September of 2004, and in the latter the populational peak was verified. From July to September of 2004, it was verified the most intense incidences of T. aurantii, and the highest peak occurred in August of 2004. T citricidus did not present significative correlation with any of the studied climate factors, although higher populational densities in the months of May, June and August of 2004, and the second week of January, 2005, were observed. A. spiraecola predominated over the other species, with populational peaks from May to August of 2004, and in the third week of December of 2004. The populational peak of this specie occurred in August of 2004. It was obtained a positive statistical correlation among the populations of these aphids with thermic extent and the number of dry weather days. Negative correlation, in relation to relative humidity was observed only for A. gossypii. In the space between lines of the citrus culture, 22 infestating plants were identified, among which Annona coriacea M. (Anonaceae), host for T aurantii, Bidens pilosa L. (Asteraceae), host for A. spiraecola, and the infesting Emilia sonchifolia (L) DC (Asteraceae), Sonchus oleraceus L. (Asteraceae), Cassia sp (Leguminosae), Sida glaziovii K. Sch., Sida rhombfolia L., Sida urens L. (Malvaceae), Solanum americanum Mill and Solanum erianthum D. Don (Solanaceae) infested by A. gossypii, must be controlled because they are focuses of aphids that are detrimental to the culture. As for natural enemies, the parasitoid species found more often were the hymenopters of the Aphidiidae Family, Lysiphlebus testaceipes (Cresson, 1880) and Aphidius colemani (Viereck, 1912). In the predatory group, the Coccinellidae Family presented the largest number of species, being Hippodamia convergens (Guérrin-Meneville) the most frequent, followed by Cycloneda sanguinea (Linnaeus, 1763) and then by Scymnus sp, while Olla v-nigrun (Germ., 1824), Hyperaspis (Hyperaspis) festiva (Mulsant, 1850) and Hyperaspis sp. were found in smaller quantity during the sampling period. In the predatory group, the Chrysopidae were more abundante, being identified two species: Chrysoperla externa (Hagen, 1861), Ceraeochrysa cincta (Adams, 1982) and eight examples only identified as Leucochrysa (Nodita) sp. Among the Hemerobiidae, only the specie Nusalala tesselata (Gerstaecker, 1888) was observed in small quantities on the citrus leaves.
A flutuação populacional dos afídeos Aphis spiraecola (Patch, 1914), Aphis gossypii (Glover, 1887), Toxoptera aurantii (Boyer de Foscolombe, 1841) e Toxoptera citricidus (Kirkald, 1907) foi estudada, correlacionando-as com as variações climáticas no período de maio de 2004 a abril de 2005, através do uso da Análise de correlação de Pearson. As amostragens foram realizadas, quinzenalmente, através de armadilha Möericke. As maiores densidades populacionais de A. gossypii ocorreram em agosto e setembro de 2004, neste último, constatou-se o pico populacional. No período de julho a setembro de 2004 constatou-se as maiores incidências de T. aurantii, sendo o mês de agosto de 2004 o de maior pico populacional. T. citricidus não apresentou correlação significativa com nenhum dos fatores climáticos estudados, embora tenham sido observados maiores densidades populacionais nos meses de maio, junho e agosto de 2004, e segunda semana de janeiro de 2005. A. spiraecola predominou sobre as demais espécies com picos populacionais nos períodos de maio a agosto de 2004 e na terceira semana de dezembro de 2004. O período de pico populacional desta espécie foi agosto de 2004. Foi obtida correlação estatística positiva entre as populações desses afídeos com a amplitude térmica e o número de dias de estiagem. Correlação negativa, em relação à umidade relativa, foi observada somente para A. gossypii. Foram identificadas nas entrelinhas da cultura de citros, 22 plantas infestantes, das quais Annona coriacea M. (Anonaceae), hospedeira de T. aurantii, Bidens pilosa L. (Asteraceae), hospedeira de A. spiraecola, e as infestantes Emilia sonchifolia (L.) DC (Asteraceae), Sonchus oleraceus L. (Asteraceae), Cassia sp (Leguminosae), Sida glaziovii K. Sch., Sida rhombifolia L., Sida urens L. (Malvaceae), Solanum iv 5 americanum Mill e Solanum erianthum D. Don (Solanaceae) infestadas por A. gossypii, devem ser controladas, pois são focos de afídeos prejudiciais a cultura. Com relação aos inimigos naturais, as espécies de parasitóides mais encontradas, foram os hymenópteros da Família Aphidiidae, Lysiphlebus testaceipes (Cresson, 1880) e Aphidius colemani Viereck, 1912. Do grupo dos predadores a Família Coccinellidae apresentou o maior número de espécies, sendo que Hippodamia convergens (Guérrin-Meneville) foi à espécie mais freqüente, seguida por Cycloneda sanguinea (Linnaeus, 1763) e, posteriormente, Scymnus sp, enquanto que Olla v- nigrum (Germ.; 1824), Hyperaspis (Hyperaspis) festiva Mulsant, 1850 e Hyperaspis sp., foram encontradas em menor quantidade durante o período de amostragens. Entre o grupo dos predadores, os crisopídeos foram os mais abundantes, sendo identificadas duas espécies: Chrysoperla externa (Hagen, 1861), Ceraeochrysa cincta Adams, 1982 e oito exemplares identificados apenas como Leucochrysa (Nodita) sp. Entre os Hemerobiideos, apenas a espécie Nusalala tesselata (Gerstaecker, 1888) foi observada em pequenas quantidades nas folhas de citros.

Full textThe citrus production in the state of São Paulo has been established in its majority, on soils with low organic matter and due to this fact, several aspects related to the lack of nutrients have been attributed to the low availability of organic matter. To introduce a sustainable management for the citrus production system, the producers have been adopted the use of mulch to cover the plants. This practice has proved to increase the soil organic matter content and has been recommended for mid- and long-term improvement of the physical and chemical and biological parameters of the soil, resulting in higher productivity, a better stability in crop production and higher water availability to the citrus plants. This work studied for 4 citrus growing seasons at field conditions the effects of the addition of mulch at rates of 0, 15 and 30 t.ha-1 added every year, using Tifton as source of mulch and boric acidic added to the soil at rates of 0, 6 and 12 kg.ha-1. Measures included yield (t.ha-1 and fruit number.ha-1), the soil nutrient composition, nutritional parameters associated to the physical and chemical variations in the soil due to the treatments, the isotopic δ13c carbon and δ15N nitrogen variation in the soil due to straw addition, the soil microbial biomass, the fruit (juice) quality and the economic aspects involving the use of these two practices mulch and boron, in the citrus production system. The experiment was set up in Araras, São Paulo State, in a 8-year old commercial orchard of sweet orange var. Pêra, with 9 treatments 3 rates of mulch and 3 rates of boron, 4 replicates with 4 plants for plot, in a total of 144 plants. The application of 15 t.ha-1 and 30 t.ha-1 of mulch increased 3,38 t.ha-1 (15,6%) and 8,89 t.ha-1 (41.1%) respectively, in both cases the use of mulch showed not to be economically viable, due to its high cost in the market. The fruit productivity from the mulch treatments increased 9.3% and 24.4%, in treatments with mulch added at the rates 15 t.ha-1 and 30 t.ha-1, respectively. At 0-20 cm soil depth, the microbial biomass increased when 30 t.ha-1 mulch was added, with 64.7% and 46.9%, corresponding to 0 t/ha and 15 t.ha-1 mulch, respectively. The use of Tifton grass as mulch was positively related to increases of carbon from C4-plants in the soil organic matter content, with increases after 4 years of growth as high as 44.4%, 54.8% and 60.9%, corresponding to the rates of 0, 15 and 30 t.ha-1 of mulch. Nevertheless, the addition of mulch has not affected the water content of the soil at 20 and 40 cm depth. The effect of boron was observed only at the high productivity season (more 40 t.ha-1), with the treatment of 12 kg t.ha-1 yielding 5.8 t.ha-1 (16.7%), when compared to the control (0 kg/ha B) treatment. The K/Ca ratio and the S-leaf concentration were negatively correlated with yield, when increases of one unit in K/Ca ratio corresponded to a decrease of 30 t.ha-1 and one unit of S-leaf concentration to minus 4 t.ha-1. It is recommended that K/Ca ratio should be around 0.4 and the S-leaf concentration around 3 g/kg. The leaf ratio P/S affected positively the yield, when increases of one unit in this ratio, corresponded to increases of 17 t.ha-1 in yield increases. The season (year) was an important factor, showing an alternate variation of high/low yield in every two years.

Os mecanismos envolvidos no surgimento da cardiotoxicidade são múltiplos, mas o aumento do estresse oxidativo tem papel fundamental. O suco de laranja contém muitos compostos com potencial antioxidante, como os flavonóides. A composição do suco de laranja pode diferir entre as variedades de laranja e isso pode levar a efeitos biológicos diferentes, como maior atividade antioxidante. Objetivo: Avaliar a influência do suco de laranja Pera (Citrus sinensis) e da Moro (Citrus sinensis (L.) Osbeck) na cardiotoxicidade induzida pela doxorrubicina em ratos. Material e Métodos: Foram utilizados 120 ratos Wistar machos adultos, que foram alocados em 6 grupos: C, LP, LM, D, DLP, DLM. Os grupos C e D receberam água com maltodextrina para igualar a quantidade de carboidratos dos sucos de laranja.

Abstract: Introduction: Doxorubicin is a widely used chemotherapy and very effective in the treatment of cancer, but it can lead to cardiotoxicity, which may limit it’s use. The mechanisms involved in the emergence of cardiotoxicity are multiple, but the increase of oxidative stress plays a fundamental role. Orange juice contains many compounds with antioxidant potential, such as flavonoids. The composition of orange juice may differ between orange varieties and this may lead to different biological effects such as increased antioxidant activity. Objective: To evaluate the influence of Pera (Citrus sinensis) and Moro (Citrus sinensis (L.) Osbeck) orange juice on doxorubicin-induced cardiotoxicity in rats. Material and Methods: We used 120 adult male Wistar rats, which were allocated into 6 groups: C, LP, LM, D, DLP, DLM. Groups C and D were given water with maltodextrin to equalize the amount of carbohydrate in the orange juices. The LP and DLP groups received Pera orange juice and the LM and DLM groups received Moro orange juice for 4 weeks. Afterwards, animals from groups D, DLP and DLM received doxorubicin injection (20mg / kg, PI) and animals from groups C, LP and LM received saline injection. Forty-eight hours after doxorubicin injection, the animals underwent echocardiography, left intraventricular pressure measurement and euthanasia for collection of biological material. Results: Doxorubicin-treated rats gained less weight than untreated rats, probably due to the decreased intak... (Complete abstract click electronic access below)

Full textHuanglongbing (HLB) associated to Candidatus Liberibacter spp., which colonizes the phloem, is considered one of the most serious diseases of citrus. One important strategy to control this disease consists of producing transgenic plants expressing, in the bacteria colonization tissue, genes encoding antibacterial peptides. The objective of this work was to produce transgenic sweet orange plants expressing genes encoding the antibacterial peptide attacin A (attA) driven by phoem-specific promoters. The work started with the development of the gene constructs, containing the attacin A gene (with or without signal peptide) controlled by either sucrose transporter gene (AtSuc2) or phloem protein 2 gene promoters (AtPP2) from Arabidopsis thaliana, or phloem protein 2 gene promotor (CsPP2) from Citrus sinensis. The genetic transformation of C. sinensis \'Hamlin\', \'Valencia\', \'Pera\' and \'Natal\' cultivars was done via Agrobacterium tumefaciens. Epicotyls segments collected from in vitro germinated seedlings were used as explants. Transgenic plants were identified by PCR analyses. PCR positive plants were acclimatized and transferred to specific greenhouse. Integration and transcription of the attA gene was confirmed in acclimatized transgenic plants by Southern and Northern blot analysis, respectively. The attA gene expression was validated by RT-qPCR analysis. \'Hamlin\' transgenic cultivars containing the AtSuc2 or AtPP2 promoters controlling the expression of attA (with or without signal peptide) were propagated by grafting, for future evaluation of Candidatus Liberibacter asiaticus resistance

A citricultura é uma das principais atividades do agronegócio brasileiro. Entretanto, inúmeras pragas e doenças atacam os citros, causando grandes prejuízos econômicos. O cancro cítrico, causado pela bactéria Xanthomonas citri subsp. citri (Xac), é um grave problema para o setor, não havendo ainda um método eficaz para o seu controle. Neste estudo, utilizando RNASeq, foram analisados os perfis transcricionais de Xac inoculada em duas espécies de citros contrastantes à doença: laranja doce ‘Pêra Rio’ (Citrus sinensis L. Osbeck), menos suscetível e lima ácida ‘Galego’ (Citrus aurantifolia Swingle), altamente suscetível, às 48 e 72 horas após a infecção (hai), com o objetivo de identificar genes de Xac envolvidos no processo de infecção. Foram identificados 80 genes de Xac diferencialmente expressos (GDEs) no hospedeiro laranja doce ‘Pêra Rio’, sendo 41 e 39 nos tempos de 48 e 72 hai, respectivamente. Em lima ácida ‘Galego’ foram identificados 82 GDEs, sendo 40 no tempo de 48 hai e 42 em 72 hai. Alguns destes genes diferencialmente expressos foram avaliados pela técnica de PCR quantitativa em tempo real, sendo estes hpa1, hrpE, hrpW, virK, ahpC, katE, katG, cydA e cydB, os quais estão envolvidos na patogenicidade e virulência, na defesa ao estresse oxidativo e na fosforilação oxidativa. Os genes de patogenicidade e virulência foram induzidos em Xac em ambos os hospedeiros, enquanto que os genes relacionados à cadeia respiratória foram inibidos em ambos os hospedeiros, com maior inibição em lima ácida ‘Galego’. No entanto, os genes relacionados ao estresse oxidativo apresentaram um perfil de expressão maior em Xac na interação com laranja doce ‘Pêra Rio’ do que em lima ácida ‘Galego’, principalmente ahpC e katG. A determinação da concentração de H2O2 nas folhas revelou que laranja doce ‘Pêra Rio’, espécie menos suscetível ao cancro cítrico, possui maior quantidade de H2O2 do que lima ácida ‘Galego’, espécie altamente suscetível. Isso sugere que a menor susceptibilidade ao cancro cítrico da laranja ‘Pêra Rio’ pode estar relacionada com a maior quantidade de H2O2 presente nesta espécie, o que leva a bactéria a ativar seu arsenal de enzimas para combater o estresse oxidativo do meio, retardando a infecção.
The citrus industry is one of the main activities of Brazilian agribusiness. However, many pests and diseases attack citrus, causing great economic losses. The citrus canker, caused by Xanthomonas citri subsp. citri (Xac), is a major problem for the sector, there is not yet an effective method for its control. In this study, the transcriptional profiles of Xac inoculated in two species of contrasting citrus disease were analyzed using RNA-Seq : sweet orange 'Pêra Rio' (Citrus sinensis L. Osbeck), moderately tolerant and Mexican Lime 'Galego' (Citrus aurantifolia Swingle) highly susceptible at 48 and 72 hours after infection (hai) aiming to identify Xac genes involved in the infection process. We identified 80 Xac differentially expressed genes (DGE) in sweet orange 'Pera Rio', 41 and 39 at 48 and 72 hai, respectively. In Mexican Lime 'Galego' 82 DGE were identified, 40 at 48 and 42 at 72 hai. Some of these differentially expressed genes were evaluated by real time quantitative PCR : hpa1, hrpE, hrpW, Virk, ahpC, KatE, katG, cyda and cydB, which are involved in pathogenicity and virulence, oxidative stress defense and oxidative phosphorylation. The pathogenicity and virulence genes were induced in Xac in both hosts, whereas the respiratory chain-related genes were inhibited in both hosts with greater inhibition in Mexican lime 'Galego'. However, genes related to oxidative stress showed a higher expression profile in Xac interaction with sweet orange 'Pera Rio' than with Mexican lime 'Galego', mainly ahpC and katG. The determination of H2O2 concentration in leaves revealed a higher amount of H2O2 in sweet orange 'Pêra Rio' moderately tolerant to citrus canker, than in Mexican Lime 'Galego' highly susceptible to citrus canker. The results suggests that the lower susceptibility to citrus canker orange 'Pera Rio' may be related to the greater amount of H2O2 present in this specie, which leads the bacteria to activate their arsenal of enzymes to fight oxidative stress environment, slowing the infection.

The citrus canker, caused by Xanthomonas citri subsp. citri (Xac), is a major problem for the sector, there is not yet an effective method for its control. In this study, the transcriptional profiles of Xac inoculated in two species of contrasting citrus disease were analyzed using RNA-Seq : sweet orange 'Pêra Rio' (Citrus sinensis L. Osbeck), moderately tolerant and Mexican Lime 'Galego' (Citrus aurantifolia Swingle) highly susceptible at 48 and 72 hours after infection (hai) aiming to identify Xac genes involved in the infection process. We identified 80 Xac differentially expressed genes (DGE) in sweet orange 'Pera Rio', 41 and 39 at 48 and 72 hai, respectively. In Mexican Lime 'Galego' 82 DGE were identified, 40 at 48 and 42 at 72 hai. Some of these differentially expressed genes were evaluated by real time quantitative PCR : hpa1, hrpE, hrpW, Virk, ahpC, KatE, katG, cyda and cydB, which are involved in pathogenicity and virulence, oxidative stress defense and oxidative phosphorylation. The pathogenicity and virulence genes were induced in Xac in both hosts, whereas the respiratory chain-related genes were inhibited in both hosts with greater inhibition in Mexican lime 'Galego'. However, genes related to oxidative stress showed a higher expression profile in Xac interaction with sweet orange 'Pera Rio' than with Mexica... (Complete abstract click electronic access below)
