PR1 — Brassica napus

Summary

BnPR1 (DARMORV10_C03P56070.1) on chromosome C03 of oilseed rape encodes a CAP-domain protein belonging to the CRISP-related family, with annotated cytokine activity and protein binding. This gene is associated with immune activation, salicylic acid and jasmonic acid biosynthesis, lignin anabolism, cell wall thickening, programmed cell death regulation, and secretion. It localises to the extracellular space, secretory vesicles, vacuole, and plant-type cell wall. Associations include chlorophyll and nitrogen content, and responses to cadmium, salt, acid rain, and biotic stresses such as resistance to Rhizoctonia solani, Pseudomonas syringae, Verticillium dahliae, aphids, nematodes, and systemic acquired resistance. Studies of related genes in other species link the family to salicylic acid-mediated defense, fungal disease resistance, and abiotic stress tolerance.
