Genome-wide identification of microRNAs in pomegranate (Punica granatum L.) by high throughput sequencing

ABSTRACT: Background: MicroRNAs (miRNAs), a class of small non-coding endogenous RNAs that regulate gene expression posttranscriptionally, play multiple key roles in plant growth and development and the stress response. Knowledge of and the roles of miRNAs in pomegranate fruit development have not been explored. Results: Pomegranate, which accumulates a large amount of anthocyanins in skin and arils, is valuable to human health, mainly because of antioxidant properties. In this study, we developed a small RNA library from pooled RNA samples from young seedling to matured fruits and identified both conserved and pomegranate-specific miRNA from 29,948,480 high-quality reads. For the pool of 15- to 30-nt small RNAs, ~50% were 24 nt. The miR157 family was the most abundant, followed by miR156, miR160, a
