MPK1 — Triticum aestivum

Summary

TRAESCS7D02G106400 (symbol MPK1, preferred name TaMPK6) on bread wheat chromosome 7D encodes a mitogen-activated protein kinase with MAPKK activity, protein serine/threonine kinase activity, and ATP binding. This gene is associated with numerous biological processes including chemotropism, branching morphogenesis, response to stimulus, posttranscriptional regulation of gene expression, PRR signaling pathway, hormone anabolism, secondary metabolite biosynthesis, and sulfur metabolism. It localizes to the cytoplasm and nucleus. TaMPK6 is associated with drought tolerance and drought susceptibility index, seedling vigour, stem rust and stripe rust disease responses, grain number, grain size, grain weight, grain yield, plant height, tiller number, spike length, panicle length, heat tolerance, low temperature stress response, water use efficiency, and nitrate transport. Related genes in other species are linked to freezing tolerance and spikelet number.
