Abstract

Summary: In Arabidopsis, both the membrane‐anchored receptor‐like kinase (RLK) BAK1 and the receptor‐like cytoplasmic kinase (RLCK) BIK1 are important mediators of transmembrane signal transduction that regulate plant development and immunity. However, little attention has been paid to their genetic association. This study found the bak1 bik1 double mutant of Arabidopsis displayed a severe dwarfism phenotype due to constitutive immunity and cell death in developing plants. These data suggest that BIK1 cooperates with BAK1 to regulate constitutive immunity and cell death. Abstract : bak1 bik1 double mutants showed a severe dwarfism phenotype. The constitutive immune activation was mainly responsible for the cell death and developmental defects in bak1 bik1 double mutants. This study indicated that BAK1 and BIK1 are critical for regulation of the constitutive immune response and cell death in Arabidopsis.
