miRNAs in plant development

Swarup, Ranjan; Denyer, Tom


Tom Denyer


Since the discovery of the first microRNA (miRNA) in Caenorhabditis elegans about 25 years ago, small RNAs have emerged as key players in the broad regulation of gene expression in most developmental processes in both plants and animals.
miRNAs are small (20–24 nt) noncoding RNA molecules involved in posttranscriptional regulation of gene expression.miRNAs regulate gene expression by cleavage of the target transcript and/or through translational repression. The former appears to be a more prevalent mechanism in plants whereas the later appears to be predominant in animals. The level of miRNA-target sequence complementarity typically dictates whether mRNA repression or transcript cleavage occurs.
This article will focus on our current understanding of the roles of miRNAs in plant development with a key focus on developmentally importantmiRNAs of the model plant, Arabidopsis thaliana, their modes of action, and the networks to which they belong. This article will also briefly discuss conservation of microRNAs across other plant species and directions for future research on miRNA.
