Signaling from the Endoplasmic Reticulum Activates Brassinosteroid Signaling and Promotes Acclimation to Stress in Arabidopsis

Che, ping; Bussell, John D; Zhou, Wenxu; Estavillo, Gonzalo; Pogson, Barry; Smith, Steven M


The ability to acclimate to stresses enables plants to grow and develop under adverse environmental conditions. Regulated intramembrane proteolysis (RIP) triggered by endoplasmic reticulum (ER) stress mediates some forms of stress signaling. Brassinosteroids (BRs) have been implicated in plant adaptation to stress, but no mechanisms for activation have been discovered. Here, we reveal a connection between ER stress signaling and BR-mediated growth and stress acclimation. Arabidopsis...[Show more]
