PR1 — Triticum turgidum subsp. durum

Summary

TRITD4AV1G056270 (PR1) on durum wheat chromosome 4A encodes a Bet v I/Major latex protein domain-containing protein with abscisic acid binding, protein phosphatase inhibitor, and signaling receptor activities. This gene is associated with defense response, ABA signaling, ochratoxin A anabolism, conidia formation, mycotoxin anabolism, and morphogenesis, and its product localizes to the cytoplasm and nucleus. It is linked to resistance to corn earworm. Studies of related genes in other species connect the PR1 family to traits including resistance to fall armyworm, black point incidence, hydrogen peroxide content, anthocyanin and chlorophyll content, plant height, seed germination, grain yield, and salt tolerance.
