Cytokinin regulates vegetative phase change in Arabidopsis thaliana through the miR172/TOE1-TOE2 module

Abstract

The antagonistic activities of miR156 and miR172 regulate juvenile-to-adult phase transition during plant shoot growth. Here the authors show that cytokinin promotes this transition by increasing miR172 abundance which in turn represses the activity of the transcriptional regulators TOE1 and TOE2.
