ERF1 — Brassica oleracea var. botrytis

Summary

BoERF1 (BOLND125_C01P048410.1_BOLND125_V1) on cauliflower chromosome 1 encodes a protein with an AP2/ERF domain, possessing DNA-binding and transcription coactivator activities. It is associated with diverse biological processes including carotenoid anabolism, trichome papilla formation and branching, cellular responses to drought and salinity, ethylene and jasmonic acid signaling, defense response upregulation, red and far-red light phototransduction, fruit ripening, and flower development. The gene is linked to traits such as ethylene and auxin sensitivity, jasmonic acid content, flowering time, disease tolerance, and root morphology. Phenotypic associations include pathogen resistance, heat, drought, and salt tolerance, hypocotyl elongation, stomatal aperture, lateral root development, and camalexin biosynthesis. Related genes in other species connect the family to ethylene response, resistance to fungal and bacterial pathogens, drought stress response, and root architecture.
