BREVIPEDICELLUS Interacts with the SWI2/SNF2 Chromatin Remodeling ATPase BRAHMA to Regulate and Expression in Control of Inflorescence Architecture

English version České info

BP is a class-I KNOX transcription factor that controls normal inflorescence architecture development by repressing the expression of two KNOX genes, KNAT2 and KNAT6. In this study, we showed that Arabidopsis BP directly interacts with the SWI2/SNF2 chromatin remodeling ATPase BRM. brm and bp mutants displayed similar inflorescence architecture defects, with clustered inflorescences, horizontally orientated pedicels, and short pedicels and internodes. Furthermore, BP and BRM co-target to KNAT2 and KNAT6 genes and repress their expression. This work reveals a new regulatory mechanism that BP associates with BRM in control of inflorescence architecture development.
