Title: Conveying endogenous and exogenous signals: MAPK cascades in plant growth and defense

Highlights

• MAPK cascades are conserved signaling modules downstream of cell surface receptors.

• Plant perception of endogenous and exogenous signals converges on MAPK cascades.

• Specificity of MAPK signaling relies on ligand-receptor pairs and MAPK substrates.

• RLCKs and G protein emerge as the missing links between receptors and MAPK cascades.

• A set of criteria is proposed to define physiological substrates of plant MAPKs.
