MAPK14 — Cicer arietinum

Summary

MAPK14 (MPK8) on chickpea chromosome 8 encodes a mitogen-activated protein kinase (MAPK) with serine/threonine kinase activity, calmodulin binding, and ATP binding. It is associated with intracellular signal transduction, responses to hydrogen peroxide, jasmonic acid, wounding, and defense responses, as well as systemic acquired resistance and cell death. The gene is linked to biotic plant stress trait, stomatal complex closure time, disease tolerance, seed germination, impaired stomatal response to ABA, enhanced water loss, stomatal closure, biotic stress resistance, pathogen resistance, water loss, and ROS homeostasis. It localizes to the cytosol, cytoplasm, nucleus, and mitochondria. Related genes in other species connect the family to seed maturation, dormancy, and photochemical quenching.
