MPK6 — Triticum turgidum subsp. durum

Summary

TRITD1AV1G120860 (MPK6) on durum wheat chromosome 1A encodes a mitogen-activated protein kinase with serine/threonine and tyrosine kinase activity, classified as EC 2.7.11.24. The gene is associated with intracellular signal transduction, protein phosphorylation, and regulation of gene expression, as well as responses to UV-C, wounding, and defense, including the PRR signaling pathway and innate immunity. It is linked to ABA and salicylic acid signaling, cell division, and localizes to both the cytoplasm and nucleus. Associations with brassinosteroid and strigolactone signaling, domestication, and stress responses such as drought, salt, heat, and cold tolerance have been noted. Studies of related genes in other species connect the MPK6 family to grain size, grain weight, plant architecture, embryo development, and abiotic stress tolerance.
