The maize intercropped with legume cover crops are used at low technological agriculture, due it?s potential to suppress weeds, recycle nutrients, and cover the soil. Weeds suppression it is important due to its competition effect on the commercial crops. The nutrient recycling it is important due to the low fertilizer use on low technological agriculture. The soil cover it is important to prevent the erosion and reduce the nutrients leaching. All those positive effects can be influenced due to the cultivated species on the consortium. This study aimed to evaluate the soil coverage, the phytomass production and, the accumulation of nutrients by plants in a maize and legume cover crops intercropping system. The experiment consisted of rustic maize ?Caiano de Sobrália? variety, intercropped with Brazilian velvet bean, black mucuna, lablab-bean and pigeon pea; a control treatment (sole maize culture) was added. The maize was sown on the experiment; 64 DAE, the legumes were sowed. The soil cover rates were evaluated at 0, 64, 84, 120, and 144 DAE. The corn grains were harvested at 120 DAE, resulting in the corn grain yields. The remaining portion of maize and entire legume cover crop plants were sampled at 144 DAE, when the accumulation of dry mass and nutrient were measured. The consortium system did not affect the corn grains yield and, the soil cover rate provided by maize plants. The black mucuna had the greatest weeds suppression and, nutrient accumulation among the legumes cover crops evaluated.

Huanglongbing (HLB) is known as the most devastating disease of citrus. Two species of Candidatus Liberibacter have been reported in Brazil, Ca. L. asiaticus (CaLas) and Ca. L. americanus (CaLam). Since CaLas is prevalent worldwide, most of the studies have focused that species and very little information is available on CaLam. With the objective to investigate differences in metabolic pathways of Citrus sinensis in response to CaLam, we used a genome- wide microarray approach to identify differentially expressed genes in symptomatic plants when compared to control plants. Hybridizations were performed by Roche Nimblegen with a customized 385K chip containing 32,000 unigenes of C. sinensis. The raw data were pre-processed using the Robust Multiarray Average (RMA). Normalized data were imported to R/Bioconductor where statistical analyses were performed. A Bayesian moderated t-test was calculated and p-values were adjusted for multiple comparisons by the false discovery rate correction. A total of 634 genes with P-values ?0.05, fold change |FC| ? 2.0 and odds probability ? 0.95 were considered differentially expressed. From those, 419 were up- and 215 down-regulated in symptomatic plants. In order to identify enriched gene ontologies regulated in infected plants we applied a gene set enrichment analysis approach and found 45 different biological processes including those involved in response to jasmonic acid stimulus, signaling and metabolism, 17 molecular functions, including oxygen binding, monooxygenase activity and oxidoreductase activity, 6 cellular components, mostly related to chloroplast, enriched at a statistically significant level of 0.001.
