PR1 — Brassica oleracea var. botrytis

Summary

BoPR1, located on chromosome 3 of cauliflower (Brassica oleracea var. botrytis), encodes a protein containing a CAP domain (cysteine-rich secretory protein-related family) and is annotated with cytokine activity and protein binding functions. This gene is associated with a wide range of defense-related processes, including activation of immune response, defense response to other organisms and fungi, systemic acquired resistance, and salicylic acid signaling. It is also linked to responses to ethylene, thiamin, and stress, as well as sexual reproduction and cell killing. The encoded protein localizes to the secretory vesicle, vacuole, plant-type cell wall, and extracellular space. Studies of related genes in other species link the family to pathogen resistance, fungal disease resistance, salicylic acid-mediated defense, and abiotic stress tolerance, as well as traits such as biomass yield, chlorophyll content, drought tolerance, and root length.
