PR1 — Brassica oleracea

Summary

BoPR1, located on chromosome 8 of cabbage (Brassica oleracea), encodes a protein belonging to the CRISP-related CAP domain family. The gene product is associated with cytokine activity and protein binding. BoPR1 is linked to a wide range of defense-related processes, including immune response activation, systemic acquired resistance, and defense against various pathogens such as Rhizoctonia solani, Pseudomonas syringae, and Verticillium dahliae. It has also been connected to responses to abiotic stresses like cadmium, salt, and acid rain, as well as to salicylic acid signaling. Additionally, BoPR1 is associated with glucosinolate biosynthesis, cell death, lateral root development, and sexual reproduction. The protein localizes to the extracellular space, plant-type cell wall, vacuole, and secretory vesicles. Studies of related genes in other species link the PR1 family to pathogen resistance, herbivore defense, and abiotic stress tolerance.
