PR1 — Brassica napus

Summary

BnPR1 (DARMORV10_C08P05250.1) on chromosome C08 of oilseed rape encodes a CRISP-related protein containing a CAP domain, with cytokine activity and protein binding functions. This gene is associated with immune activation, salicylic acid and jasmonic acid biosynthesis, lignin anabolism, cell wall thickening, programmed cell death regulation, detoxification, secretion, and sexual reproduction. It localizes to secretory vesicles, vacuoles, the plant cell wall, and extracellular space. BnPR1 is linked to chlorophyll and nitrogen content, and to numerous defense-related phenotypes including systemic acquired resistance, resistance to pathogens such as Rhizoctonia solani, Pseudomonas syringae, Verticillium dahliae, and Alternaria brassicicola, as well as salt tolerance, aphid resistance, and nematode resistance. Related genes in other species are linked to salicylic acid-mediated defense, fungal disease resistance, and abiotic stress tolerance.
