PR1 — Triticum turgidum subsp. durum

Summary

TRITD7AV1G052120 (PR1) on durum wheat chromosome 7A encodes a pathogenesis-related protein 1. The gene product is associated with abscisic acid binding, nuclease activity, hydrolase activity, signaling receptor activity, and protein phosphatase inhibitor activity. It is linked to defense response, ABA signaling, morphogenesis, and the anabolism of flavonoids, ochratoxin A, and mycotoxins, and is localized to the cytoplasm and nucleus. The gene is also associated with resistance to corn earworm. Studies of related genes in other species link the PR1 family to traits including grain yield, plant height, seed germination, chlorophyll and anthocyanin content, crop stand, hydrogen peroxide levels, black point incidence, and resistance to fall armyworm and European corn borer.
