Abstract

Abstract:

Brassinosteroid (BR) is a class of plant-specific steroidal hormone and plays vital roles in plant growth, developmental and stress response. As the core component of BR signaling, the BES1/BZR1 transcription factors are activated by the BR signal, bind to the E-box (CANNTG) or BRRE element (CGTGT/CG) enriched in the promoter of downstream target genes and regulate their expression. Besides BR signal transduction, BES1/BZR1s are also involved in other signaling pathways such as abscisic acid, gibberellin and light to co-regulate plant growth and development. Recently, BES1/BZR1s were found to be related to stress resistance. In this review, we summarize recent advances of molecular mechanism of the BES1/BZR1 transcription factors regulating plant growth, development and stress resistance through signal transduction to provide a reference for related researches.

Key words: brassinosteroid, growth and development, signal transduction, stress resistance, BES1/BZR1 transcription factors
