SOB3 — Camelina sativa

Summary

CsSOB3 (CSA07G048070) on Camelina sativa chromosome 7 encodes a DNA-binding transcription factor with AT-binding, histone-binding, and promoter-specific chromatin-binding activities, as well as red/far-red light photoreceptor activity and phosphorelay sensor kinase activity. The protein belongs to the AHL15-29 family and localises to the nucleus, cytosol, and plasmalemma. CsSOB3 is associated with light signalling pathways, circadian regulation, stomatal development, geotropism, and responses to thermal and hydrogen peroxide stimuli. It has been linked to agronomically relevant traits including biomass yield, water use efficiency, leaf angle, photosynthetic ability, transpiration rate, photoperiod-sensitive flowering time, and glyphosate sensitivity. Studies of related genes in other species connect the family to flowering time, plant height, yield, and photomorphogenesis.
