BES1 is activated by EMS1-TPD1-SERK1/2-mediated signaling to control tapetum development in Arabidopsis thaliana

Abstract

BES1 and BZR1 transcription factors are activated by the BRI1-BAK1 receptor complex during brassinosteroid signaling. Here the authors show that BES1-family members also act in anthers, downstream of another receptor-like kinase-mediated signaling pathway, EMS1-TPD1-SERK1/2, to promote tapetum development.
