Leu-rich receptor Serine/threonine protein kinase BAK1, as a co-receptor of BRI1 (At4g39400) that mediates Brassinosteroids (BR) signaling, the functional roles of BAK1, as a versatile co-receptor for various ligand-Binding leucine-rich repeat (LRR) -containing receptor-like kinase (RLKs) , are Being extended to involvement with plant immunity, cell death, stomatal development and ABA signaling in plants.
