PR1 — Brassica napus

Summary

BnPR1 (DARMORV10_C03P56080.1) on chromosome C03 of oilseed rape encodes a CAP-domain-containing protein with cytokine activity and protein binding capacity. The gene is associated with salicylic acid and jasmonic acid anabolism, activation of immune response, regulation of programmed cell death, cell wall thickening, lignin anabolism, and secretion. It is linked to systemic acquired resistance, defense against diverse pathogens including Rhizoctonia solani, Pseudomonas syringae, Verticillium dahliae, and Alternaria brassicicola, as well as responses to cadmium, acid rain, salt stress, and insect egg deposition. Associations with chlorophyll content, nitrogen content, and proline metabolism have also been observed. Studies of related genes in other species connect the family to disease resistance, systemic immunity, herbivore defense, and abiotic stress tolerance.
