Identification and validation of plant miRNA from NGS data-an experimental approach.

miRNAs are class of endogenously initiated noncoding RNAs, which are most critical in gene expression and regulation at posttranscriptional level. They do so either by cleavage of the target mRNA or by translational repression. miRNAs are being given enough attention in recent years because of its role in myriad developmental processes including tumorogenesis and host-pathogen interaction.
