CPR5 — Brassica oleracea var. botrytis

Summary

BoCPR5 (BOLND125_C03P056640.1_BOLND125_V1) on cauliflower chromosome 3 encodes a protein with a CPR5_C domain and exhibits kinase inhibitor activity, including cyclin-dependent protein kinase inhibitor activity, along with mRNA and protein binding. This gene is associated with negative regulation of the cell cycle, downregulation of mitosis, and upregulation of DNA endoreduplication, and is linked to trichome differentiation and morphogenesis, sepal giant cell development, and leaf senescence. It is associated with defence responses, including response to other organisms, defence response to bacteria, and hypersensitive response-programmed cell death, as well as jasmonic acid/ethylene-mediated systemic resistance, sugar-mediated signalling, photoperiodism and flowering, and response to ethylene. Localisation evidence places the product at the nuclear envelope, nucleus, endoplasmic reticulum, membrane, and nuclear speck. Related genes in other species are linked to constitutive systemic acquired resistance, pattern-triggered immunity, ethylene sensitivity, cell size, and powdery mildew resistance.
