A loop-to-base processing mechanism underlies the biogenesis of plant microRNAs miR319 and miR159

The first step in microRNA (miRNA) biogenesis usually involves cleavage at the base of its fold-back precursor. Here, we describe a non-canonical processing mechanism for miRNAs miR319 and miR159 in Arabidopsis thaliana. We found that their biogenesis begins with the cleavage of the loop, instead of...
