Crosstalk between secondary messengers, hormones and MAPK modules during abiotic stress signalling in plants

The crosstalk between second messengers, hormones and mitogen-activated protein kinases (MAPKs) in plant signalling systems facilitates adaptation and survival in the face of diverse environmental stresses. This review focuses on the transduction of second messenger and hormone signals by MAPK modules in plant abiotic stress responses. We discuss how this crosstalk regulates gene expression (e.g. by controlling transcription factor activity) and other cellular and physiological responses to enable adaptation and/or resistance to abiotic stresses.
