PR1 — Brassica oleracea var. botrytis

Summary

BoPR1, located on cauliflower chromosome 8, encodes a CRISP-related protein containing a CAP domain. The gene is associated with cytokine activity and protein binding, and is linked to immune response activation, defense against fungi and other organisms, and sexual reproduction. It localizes to the secretory vesicle, vacuole, plant-type cell wall, and extracellular space. BoPR1 is associated with systemic acquired resistance, salicylic acid signaling, and resistance to pathogens including Rhizoctonia solani, Pseudomonas syringae, Verticillium dahliae, and nematodes, as well as with salt tolerance, cadmium response, and aphid resistance. Related genes in other species link the family to salicylic acid-mediated defense, abiotic stress tolerance, and resistance to Botrytis cinerea and Cucumber mosaic virus.
