PR1 — Brassica oleracea

Summary

BoPR1 (BOLC102_C03P059860.1) on cabbage chromosome 3 encodes a protein belonging to the CAP superfamily, containing a CAP domain and a CRISP-related region, and is annotated with cytokine activity and protein binding. This gene is associated with immune response activation, defense against other organisms, cell death, jasmonic acid signaling, glucosinolate and indole glucosinolate biosynthesis, lateral root development, sexual reproduction, secretion, sulfation, and response to thiamin. It is linked to salicylic acid signaling, systemic acquired resistance, and resistance to pathogens including Rhizoctonia solani, Pseudomonas syringae, Verticillium dahliae, and Alternaria brassicicola, as well as to salt tolerance, cadmium response, acid rain response, and insect egg deposition defense. The protein localizes to the extracellular space, plant-type cell wall, vacuole, and secretory vesicles. Studies of related genes in other species connect the family to disease resistance, systemic immunity, and abiotic stress tolerance.
