PR1 — Brachypodium distachyon

Summary

BRADI_1G64910V3 (PR1) on chromosome 1 of Brachypodium distachyon encodes a Bet v I/MLP domain-containing protein with abscisic acid binding, protein phosphatase inhibitor, and signaling receptor activities. The gene is associated with immune and defense responses, ABA signaling, and localizes to both the cytoplasm and nucleus. PR1 is linked to resistance to corn earworm. Studies of related genes in other species connect the family to traits including European corn borer resistance, armyworm response, black point incidence in Fusarium, hydrogen peroxide and anthocyanin content, chlorophyll content, plant height, seed germination, grain yield, and salt tolerance, as well as resistance to fall armyworm.
