PR1 — Brassica juncea

Summary

BJUB02G09700S (BjPR1) on chromosome B02 of Indian mustard encodes a CAP-domain-containing protein with cytokine activity and protein binding capacity. The gene is associated with immune activation, defense responses to fungi and other organisms, cell death, seed germination, sexual reproduction, and sterol and isoprenoid anabolism. It localizes to secretory vesicles, vacuoles, the plant cell wall, and the extracellular space. BjPR1 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 are associated with fungal disease resistance, herbivore defense, and abiotic stress tolerance.
