Abstract:Summary
Brassinosteroids (BRs) are plant hormones that are essential in plant growth and development. BRASSINOSTEROID‐INSENSITIVE 1 (BRI1) and BRI1 ASSOCIATED RECEPTOR KINASE 1 (BAK1), which are located on the plasma membrane, function as co‐receptors that accept and transmit BR signals.
PROHIBITIN 3 (PHB3) was identified in both BRI1 and BAK1 complexes by affinity purification and LC‐MS/MS analysis. Biochemical data showed that BRI1/BAK1 interacted with PHB3 in vitro and in vivo.
BRI1/BAK1 phosphorylated PHB3… Show more
