MPK1 — Cicer arietinum

Summary

MtMPK1, located on chickpea chromosome 5, encodes a dual-specificity protein kinase with protein serine/threonine kinase activity, ATP binding, and MAPKK activity. It is associated with intracellular signal transduction, responses to UV-C, wounding, cold, and hypotonic salinity, as well as brassinosteroid and jasmonic acid/ethylene-mediated signaling pathways. The gene has been linked to traits including grain dormancy, seed maturation, anthocyanin content, leaf temperature, root oxidative activity, phosphorus uptake, and responses to aluminum, osmotic stress, and UV-B light. Localization evidence places the product in the cytoplasm, nucleus, spindle, and cell plate. Related genes in other species link the family to ABA signaling, stomatal movement, pathogen response, and oxidative stress tolerance.
