PR1 — Triticum turgidum subsp. durum

Summary

TRITD7BV1G043610, designated TtPR1 on durum wheat chromosome 7B, encodes a protein containing a CAP (cysteine-rich secretory protein) domain and an SCP domain. The gene is associated with defense response, defense response to other organisms, mycotoxin anabolism, ochratoxin A anabolism, conidia formation, and morphogenesis. Its product localizes to the extracellular region and vacuole. Related genes in other species encode pathogenesis-related proteins of the PR-1 family, though these roles are not yet established for TtPR1 itself.
