BOLND125_C07P009690.1_BOLND125_V1 — Brassica oleracea var. botrytis

Summary

BoPIF1 (BOLND125_C07P009690.1_BOLND125_V1) on cauliflower chromosome 7 encodes a PIF3-like basic helix-loop-helix transcription factor with phytochrome-binding, red/far-red light photoreceptor, and transcription regulator activities. This gene is associated with positive and negative regulation of phytochrome signaling, thermomorphogenesis, response to light intensity and quality, osmotic stress, and biotic stimuli. It has been linked to numerous agronomic traits including grain yield, flower diameter, fruit set and quality, leaf area and angle, seed protein content, total soluble sugar content, iron content, vegetative vigor, peduncle length, panicle number, root morphology, and responses to UV-A, blue, and far-red light, glyphosate, nematodes, and submergence. Localization evidence connects the product to plastid RNA polymerase complexes, chloroplast nucleoids, nuclear speckles, and ubiquitin ligase complexes. Studies of related genes in other species further link it to shade avoidance, circadian rhythm, seed dormancy, and stress responses.
