PIF4 — Brassica oleracea
Summary
BoPIF4 (BOLC102_C04P074300.1) on cabbage chromosome 4 encodes a basic helix-loop-helix (bHLH) transcription factor of the PIF3-like family, with transcription coactivator activity, phytochrome binding, and red/far-red light photoreceptor activity. This gene is associated with positive regulation of thermomorphogenesis, phytochrome signaling, and auxin biosynthesis, as well as responses to light intensity, water-immersion stress, and UV protection. It has been linked to numerous agronomic traits including grain yield, flower diameter, fruit quality, total soluble sugar content, leaf angle, vegetative vigor, photosynthetic ability, and seed set percent. Additional associations include regulation of anthocyanin metabolism, internode patterning, negative gravitropism, and circumnutation. Studies of related genes in other species connect the family to shade avoidance, high temperature acclimation, drought stress response, and flowering time regulation.
