PYL7 — Brachypodium distachyon

Summary

BdPYL7 (BRADI_3G09580V3) on Brachypodium distachyon chromosome 3 encodes a protein with abscisic acid binding, protein phosphatase inhibitor activity, and signaling receptor activity, belonging to the START-like domain superfamily and plant hormone signal transduction family. It is associated with regulation of abscisic acid mediated signaling, both upregulation and downregulation, as well as positive regulation of auxin mediated signaling, regulation of salicylic acid and jasmonic acid mediated signaling pathways, and activation of defense response to bacteria. The gene is linked to downregulation of seed dormancy, release of seed from dormancy, upregulation of seed germination, regulation of stomatal opening, and inhibition of salinity response. Associations with agronomic traits include seed yield, water use efficiency, transpiration rate, vegetative vigor, phosphorus uptake, nitrate sensitivity, shoot growth angle, and responses to wheat powdery mildew and aphids.
