PR1 — Triticum turgidum subsp. durum

Summary

TRITD5AV1G005340 (PR1) on durum wheat chromosome 5A encodes a Bet_v_I/MLP domain-containing protein with abscisic acid binding, nuclease, protein phosphatase inhibitor, hydrolase, and signaling receptor activities. It is associated with defense response, ABA signaling, ochratoxin A and mycotoxin anabolism, conidia formation, and morphogenesis, and localizes to the cytoplasm and nucleus. The gene is linked to resistance to corn earworm. Studies of related genes in other species connect the family to traits including ECB resistance, armyworm response, black point incidence, hydrogen peroxide content, anthocyanin and chlorophyll content, plant height, seed germination, grain yield, and salt tolerance, as well as resistance to fall armyworm.
