MKK3 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.5HG0537440 (HvMKK3) on barley chromosome 5H encodes a mitogen-activated protein kinase kinase (MAPKK) with EC 2.7.12.2, possessing MAPKK, MEKK, and protein serine/threonine kinase activities, and contains a protein kinase domain and an NTF2-like domain. The gene is associated with the MAPK cascade, regulation of defense response to insect, induced systemic resistance mediated by ethylene and jasmonic acid signaling, downregulation of stomatal opening, response to desiccation, and positive regulation of leaf senescence. It is linked to grain dormancy, sprouting tolerance, drought tolerance, salt tolerance, photosynthetic rate, seed protein content, flowering time, and disease tolerance. Related genes in other species are linked to drought stress resistance, resistance to fungal pathogens, insect herbivory resistance, and phosphate deficiency response.
