PYL3 — Triticum aestivum

Summary

TRAESCS7B02G232100, symbol PYL3 and preferred name TaPYL7 on bread wheat chromosome 7B, encodes a protein with abscisic acid binding, protein phosphatase inhibitor activity, signaling receptor activity, and protein homodimerization activity, belonging to the polyketide cyclase/dehydrase and START-like domain superfamily. This gene is associated with ABA signaling, seed germination, seedling development, homeostasis, osmotic response, salinity response, response to thirst, and response to cold. It is linked to drought response in wheat. Associations include grain iron and zinc content, grain yield, test weight, harvest index, water use efficiency, net photosynthetic rate, proline content, starch content, and stand establishment. The protein localizes to the cytosol, cytoplasm, and nucleus. Studies of related genes in other species link the family to ABA response.
