摘要
Abstract Brassinosteroid-insensitive 1 (BRI1)-EMS suppressor 1 (BES1) and Brassinazole-resistant 1 (BZR1) are two highly similar master transcription factors of the brassinosteroid (BR) signaling pathway that regulates a variety of plant growth and development processes as well as stress responses. Previous genetic and biochemical analyses have established a complex regulatory network to control the two transcription factors. This network includes coordination with other transcription factors and interactors, multiple post-translational modifications (PTMs) and differential subcellular localizations. In this review, we systematically detail the functions and regulatory mechanisms of various PTMs: phosphorylation/dephosphorylation, ubiquitination/deubiquitination, SUMOylation/deSUMOylation and oxidation/reduction, in regulating the subcellular localization, protein stability and the transcriptional activity of BES1/BZR1. We also discuss the current knowledge about the BES1/BZR1 interactors mediating the dynamic nucleocytoplasmic shuttling of BES1 and BZR1.
