PR-1 — Brachypodium distachyon

Summary

BRADI_3G53681V3 (symbol PR-1) on chromosome 3 of Brachypodium distachyon encodes a protein belonging to the CAP superfamily, which includes a CRISP-related domain and an Allrgn_V5/Tpx1_CS motif. This gene is associated with defence responses, including defence response to fungi, defence response to other organisms, and cell death, and is linked to killing of cells of other organisms. The encoded protein localises to the extracellular region and vacuole. Studies of related genes in other species connect the PR-1 family to seed germination and drought tolerance, though these associations are not yet established in B. distachyon.
