PR1 — Triticum turgidum subsp. durum

Summary

TRITD7BV1G026800, designated PR1 on durum wheat chromosome 7B, encodes a Bet v I/Major latex protein domain-containing protein. The product is associated with abscisic acid binding, nuclease activity, protein phosphatase inhibitor activity, hydrolase activity, and signaling receptor activity. It is linked to defense response, ABA signaling, morphogenesis, and the anabolism of flavonoids, ochratoxin A, and mycotoxins, as well as conidia formation. The protein localizes to both the cytoplasm and nucleus. Studies of related genes in other species connect the family to nuclease activity (EC 3.1.27.-).
