Calcium-dependent ABA signaling functions in stomatal immunity by regulating rapid SA responses in guard cells.

Journal of plant physiology - 1 Jan 2022

Abstract excerpt

Stomatal immunity is mediated by ABA, an osmotic stress-responsive phytohormone that closes stomata via calcium-dependent and -independent signaling pathways. However, the functional involvement of ABA signal transducers in stomatal immunity remains poorly understood. Here, we demonstrate that stomatal immunity was compromised in mutants of the ABA signaling core. We also found that it is a subset of...
