PR1 — Brassica napus

Summary

BnPR1 (DARMORV10_A03P45230.1) on chromosome A03 of oilseed rape encodes a CAP-domain-containing protein with cytokine activity and protein binding capability. The gene is associated with salicylic acid and jasmonic acid anabolism, immune response activation, programmed cell death regulation, and cell wall thickening. It has been connected to chlorophyll and nitrogen content, as well as numerous stress responses including resistance to Rhizoctonia solani, Pseudomonas syringae, Verticillium dahliae, aphids, nematodes, and bacterial wilt. Localisation evidence links the product to secretory vesicles, the vacuole, plant-type cell walls, and the extracellular space. Related genes in other species connect the family to salicylic acid-mediated defence, systemic immunity, and resistance to Botrytis cinerea, Cucumber mosaic virus, and Fusarium oxysporum, as well as drought tolerance and pollen fertility.
