PR1 — Triticum turgidum subsp. durum

Summary

TRITD4BV1G117510 (PR1) on durum wheat chromosome 4B encodes a Bet v I/Major latex protein 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, ochratoxin A and mycotoxin anabolism, conidia formation, flavonoid anabolism, and morphogenesis, and its product localizes to the cytoplasm and nucleus. PR1 is linked to resistance to corn earworm. Studies of related genes in other species connect the family to 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, and salt tolerance.
