PR1 — Triticum turgidum subsp. durum

Summary

TRITD5BV1G217140 (symbol PR1, also known as TtPR1) on durum wheat chromosome 5B encodes a SCP domain-containing protein belonging to the CAP superfamily, including the V5 allergen-like and CRISP-related domains. The gene is associated with defense responses, particularly defense response to other organisms, and is linked to mycotoxin and ochratoxin A anabolism, conidia formation, and morphogenesis. The encoded protein is localized to the extracellular region and the vacuole. Studies of related genes in other species link this gene family to pathogenesis-related protein functions, though these associations are not yet established for this specific durum wheat gene.
