Abstract excerpt

Brassinosteroid (BR) promotes hypocotyl growth at warm temperatures through BZR1 by directly regulating the expression of PIF4, or by interacting with PIF4 to enhance its downstream gene expression; however, how BZR1 level is modulated by warm temperature is not known. We found that the Homology to E6-Associated Carboxy-Terminus (HECT) E3 ubiquitin ligase UPL3 plays an important role in regulating the...
