Specificity of plant microRNA target MIMICs: Cross-targeting of miR159 and miR319.

Abstract excerpt

Plant microRNA (miRNA) target MIMICs (MIMs) are non-coding RNA transcripts that can inhibit endogenous miRNAs, as they contain a miRNA binding site that forms a three nucleotide (nt) mismatch loop opposite the miRNA cleavage site upon miRNA binding. This loop renders the MIMs non-cleavable, presumably leading to sequestration of the miRNA and thus enabling the endogenous targets to be deregulated. Arabidopsis...
