PR-1 — Brachypodium distachyon

Summary

BRADI_3G53637V3 (PR-1) on chromosome 3 of Brachypodium distachyon encodes a protein containing a CAP domain, characteristic of the PR-1 family of pathogenesis-related proteins. The gene is associated with defense responses to other organisms, cell death, and general defense response, based on ontology annotations. Its product is localized to the extracellular region and the vacuole. Studies of related genes in other species link the PR-1 family to drought tolerance, chlorophyll content, and sugar content, including total soluble sugar levels.
