PYL1 — Brachypodium distachyon

Summary

BRADI_3G08580V3 (BdPYL1) on chromosome 3 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-mediated signaling, stomatal opening and movement, seed dormancy release, germination, and defense responses to bacteria. It is linked to traits including drought resistance, osmotic and salt stress tolerance, vegetative vigor, seed yield, transpiration rate, anthocyanin content, and responses to high temperature, salinity, and flooding. Studies of related genes in other species connect the family to ABA signaling, drought tolerance, grain yield, and biotic stress responses.
