PR1 — Brachypodium distachyon

Summary

BRADI_1G64920V3 (PR1) on chromosome 1 of Brachypodium distachyon encodes a Bet_v_I/MLP domain-containing protein with abscisic acid binding, nuclease, protein phosphatase inhibitor, hydrolase, and signaling receptor activities. The gene is associated with immune and defense responses and ABA signaling, and its product localizes to the cytoplasm and nucleus. PR1 is associated with resistance to corn earworm. Studies of related genes in other species link the family to traits including resistance to fall armyworm, European corn borer resistance, armyworm response, black point incidence, hydrogen peroxide content, anthocyanin and chlorophyll content, plant height, seed germination, grain yield, crop stand, plant color, and salt tolerance.
