摘要: Drought and salinity are two major environmental factors adversely affecting plant growth productivity. However, the regulatory mechanism is unknown. In this study, potential roles of small microRNAs (miRNAs) in cotton response to those stresses were investigated. Using next-generation deep sequencing, a total 337 miRNAs with precursors identified, comprising 289 known 48 novel miRNAs. Of these miRNAs, 155 expressed differentially. Target prediction, Gene Ontology (GO)-based functional classification, Kyoto Encyclopedia Genes Genomes (KEGG)-based enrichment show that might play drought through targeting series stress-related genes. Degradome sequencing analysis showed at least 55 predicted target genes further validated be regulated by 60 CitationRank-based literature mining was employed determinhe importance related stress. The NAC, MYB, MAPK families ranked top under context salinity, indicating their important for combat According associated top-ranked genes, including miR164, miR172, miR396, miR1520, miR6158, ghr-n24, ghr-n56, ghr-n59. Interestingly, 163 also identified 210 fibre development. These results will contribute stress-resistant breeding as well understanding
