Brassinosteroids (BRs) regulate a variety of physiological processes in plants via extensive crosstalk with diverse biological signaling networks. Although BRs are known to reciprocally regulate circadian oscillation, the molecular mechanism underlying BR-mediated regulation of circadian clock remains unknown. Here, we demonstrate that the BR-activated transcription factor -EMS-SUPPRESSOR 1 (BES1) integrates BR signaling into the circadian network in Arabidopsis.

This study functionally characterized the gene of , which is predicted to encode a Zn(II)Cys zinc finger transcription factor. To investigate the role of , deleted and complemented strains of in were generated, which were designated as Δ and PdeRc, respectively.

In higher plants, shoot apical meristem (SAM) maintains cell division activity in order to give rise to aerial plant organs. Several lines of evidence have suggested that plants ensure stem cell proliferation activity in response to various external stimuli, thereby contributing to plant adaptation and fitness. Here, we report that the abscisic acid (ABA)-inducible R2R3-type MYB96 transcription factor regulates transcript accumulation of SHOOT MERISTEMLESS (STM) possibly to contribute to plant adaptation to environmental stress.
