PYL1 — Triticum aestivum

Summary

TRAESCS1D02G293600, designated TaPYL1 on bread wheat chromosome 1D, encodes a protein with abscisic acid binding, protein phosphatase inhibitor activity, and kinase regulator activity. The gene is associated with regulation of stomatal opening, release of seed from dormancy, downregulation of seed dormancy process, upregulation of seed germination, response to desiccation, and activation of defence response to bacteria. It is associated with traits including grain width, harvest index, ear number, seed yield, vegetative vigor, shoot growth angle, root system morphology, and wheat powdery mildew disease response, osmotic response sensitivity, high temperature stress response, and nitrate sensitivity. Related genes in other species are linked to drought tolerance, water use efficiency, salinity tolerance, and grain yield. The product localises to the cytosol, plasmalemma, tonoplast, plastid, mitochondria, and Golgi complex.
