PR1 — Triticum turgidum subsp. durum

Summary

TRITD5BV1G216900, designated TtPR1 on durum wheat chromosome 5B, encodes a SCP domain-containing protein belonging to the CAP superfamily, which includes the V5 allergen-like and CRISP-related domains. This gene is associated with defense responses to other organisms and general defense response, as well as with mycotoxin and ochratoxin A anabolism, conidia formation, and morphogenesis. The encoded protein is localized to the extracellular region and the vacuole. Related genes in other species encode pathogenesis-related PR-1 proteins, though these associations are not yet established for TtPR1 itself.
