PR1 — Brachypodium distachyon

Summary

BRADI_1G64880V3 (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. This gene is associated with immune and defense responses, abscisic acid signaling, and flavonoid biosynthesis, and its product localizes to both the cytoplasm and nucleus. PR1 is associated with resistance to corn earworm. Studies of related genes in other species connect the family to traits including resistance to fall armyworm, European corn borer resistance, black point incidence, hydrogen peroxide content, anthocyanin and chlorophyll content, plant height, seed germination, grain yield, and salt tolerance.
