PR1 — Triticum turgidum subsp. durum

Summary

TRITD5BV1G217110, designated TtPR1 on durum wheat chromosome 5B, encodes a SCP domain-containing protein belonging to the CAP superfamily, including V5 allergen-like and CRISP-related domains. This gene is associated with defense responses to other organisms and general defense response, as well as mycotoxin and ochratoxin A anabolism, conidia formation, and morphogenesis. The product localizes to the extracellular region and vacuole. Related genes in other species link this gene family to pathogenesis-related protein functions, including PR-1A, PR-1B, and PR-1C types, though these associations are not directly established for TtPR1 itself.
