SERKs, shared co-receptors in multiple cell signaling pathways in <italic>Arabidopsis</italic>

Abstract

Somatic embryogenesis receptor-like kinases (SERKs) belong to the subfamily II of leucine-rich repeat receptor-like kinases (LRR-RLKs). Recent studies found that SERKs function as co-receptors in multiple plant cell signaling processes controlling development and defense, including brassinosteroid signal transduction, male sporogenesis, stomatal patterning, vascular tissue differentiation, floral organ abscission, cell death control, and innate immunity responses. This review summarizes the functions of SERKs in these processes in Arabidopsis .
