Identifying High Confidence microRNAs in the Developing Seeds of Jatropha curcas.

ABSTRACT: MicroRNAs (miRNAs) are endogenously short noncoding regulatory RNAs implicated in plant development and physiology. Nine small RNA (sRNA) libraries from three typical seed developmental stages (young, intermediate, and mature) were generated by deep sequencing to identify the miRNAs of J. curcas, a potential oilseed crop for the production of renewable oil. Strict criteria were adopted to identify 93 high confidence miRNAs including 48 conserved miRNAs and 45 novel miRNAs. Target genes of these miRNAs were involved in a broad range of physiological functions, including gene expression regulation, primary & secondary metabolism, growth & development, signal transduction, and stress response. About one third (29 out of 93) miRNAs showed significant changes in expression levels during the see
