PYL1 — Brachypodium distachyon

Summary

BRADI_2G53840V3 (BdPYL1) on chromosome 2 of Brachypodium distachyon encodes a protein with abscisic acid (ABA) binding, protein phosphatase inhibitor, and kinase regulator activities, belonging to the polyketide cyclase/dehydrase and START-like domain superfamilies. The gene is associated with regulation of ABA and gibberellic acid signaling, stomatal opening and movement, seed dormancy release and germination, and activation of defence responses to bacteria and salinity. It has been linked to numerous agronomic traits including seed yield, vegetative vigor, shoot growth angle, leaf position, transpiration rate, anthocyanin content, and responses to osmotic, high temperature, low temperature, and salinity stress. Related genes in other species are linked to ABA-regulated gene expression, transpiration, heat tolerance, and biomass.
