Abstract

Small, 21–22 nucleotide long RNAs called microRNAs play an essential role in the spatial and temporal regulation of gene expression. They are often part of complex gene networks. By controlling the stability or translation of their target mRNAs they have an influence on many developmental pathways. Juvenile to adult transition, initiation of flowering or plant architecture and leaf morphology are examples of miRNA-regulated processes during plant development.
