The off-season period for açaí palm production cause social and economic problems that affect producers and consumers. Two species are used for açaí pulp production, Euterpe oleracea and E. precatoria. These species have some distinct characteristics, including the harvest period. The cultivation of açaí palm is expanding in the metropolitan region of Manaus, state of Amazonas, AM, and there are no studies on the harvest period of these species under cultivated conditions in this region. The objective of this study was to evaluate the reproductive phenophases of the açaí palm E. oleracea and E. precatoria grown in the metropolitan region of Manaus, state of Amazonas and to check the harvest period of these species in this region. O período de entressafra da produção de frutos de açaí traz problemas de ordem social e econômica que afetam produtores e consumidores. Duas espécies são utilizadas para produção da polpa do açaí, Euterpe oleracea e E. precatoria. Essas espécies apresentam algumas características distintas, incluindo o período de safra. Não existem estudos, com relação a essas espécies, sobre o período de safra do açaizeiro na região metropolitana de Manaus, AM, onde a cultura está em expansão. Assim, objetivou-se com esse trabalho estudar a distribuição mensal da produção de frutos dos açaizeiros E. oleracea e E. precatoria cultivados na região metropolitana de Manaus, Amazonas. |

Background: Small RNAs (19-24 nt) are key regulators of gene expression that guide both transcriptional and posttranscriptional silencing mechanisms in eukaryotes. Current studies have demonstrated that microRNAs (miRNAs) act in several plant pathways associated with tissue proliferation, differentiation, and development and in response to abiotic and biotic stresses. In order to identify new miRNAs in soybean and to verify those that are possibly water deficit and rust-stress regulated, eight libraries of small RNAs were constructed and submitted to Solexa sequencing. Results: The libraries were developed from drought-sensitive and tolerant seedlings and rust-susceptible and resistant soybeans with or without stressors. Sequencing the library and subsequent analyses detected 256 miRNAs. From this total, we identified 24 families of novel miRNAs that had not been reported before, six families of conserved miRNAs that exist in other plants species, and 22 families previously reported in soybean. We also observed the presence of several isomiRNAs during our analyses. To validate novel miRNAs, we performed RT-qPCR across the eight different libraries. Among the 11 miRNAs analyzed, all showed different expression profiles during biotic and abiotic stresses to soybean. The majority of miRNAs were up-regulated during water deficit stress in the sensitive plants. However, for the tolerant genotype, most of the miRNAs were down regulated. The pattern of miRNAs expression was also different for the distinct genotypes submitted to the pathogen stress. Most miRNAs were down regulated during the fungus infection in the susceptible genotype; however, in the resistant genotype, most miRNAs did not vary during rust attack. A prediction of the putative targets was carried out for conserved and novel miRNAs families. Conclusions: Validation of our results with quantitative RT-qPCR revealed that Solexa sequencing is a powerful tool for miRNA discovery. The identification of differentially expressed plant miRNAs provides molecular evidence for the possible involvement of miRNAs in the process of water deficit- and rust-stress responses.
