Abstract: MicroRNA (miRNA), a kind of regulatory non-coding small RNA, induces degradation of target mRNA or inhibits its translation by specific or non-specific binding, thereby regulating plant growth and development. AP2, the target of miR172, encodes transcription factors that are unique to plants. miR172 regulates the expression of AP2 at the post-transcriptional or translational levels, thus regulating plant floral development, phase transition, spikelet morphology, tuber and fruit development, nodulation in legumes and stress response. Here we summarize the recent advances in the regulation of plant growth and development by miR172-AP2 regulatory module.

Key words: miR172, AP2 transcription factor, expression regulation, plant growth and development
