PR1 — Triticum turgidum subsp. durum

Summary

TRITD1BV1G046720, designated PR1 on durum wheat chromosome 1B, 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 defense response, ABA signaling, flavonoid and mycotoxin anabolism, conidia formation, morphogenesis, and ochratoxin A anabolism. Its product localises to 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 grain yield, plant height, chlorophyll content, anthocyanin content, seed germination, crop stand, hydrogen peroxide content, black point incidence, ECB resistance, armyworm response, and salt tolerance, as well as resistance to fall armyworm.
