SOB3 — Camelina sativa

Summary

CsSOB3 (CSA09G081240) on Camelina sativa chromosome 9 encodes a protein with DNA-binding transcription factor activity, histone binding, and red/far-red light photoreceptor activity, placing it in the AHL15-29 family. The gene is associated with light perception, photomorphogenesis, and circadian regulation, including red light signaling, photoacclimation, and entrainment of the circadian clock. It has been linked to abscisic acid metabolism, hydrogen peroxide-mediated signaling, and regulation of defense responses. Traits connected to CsSOB3 include biomass yield, leaf angle, photosynthetic ability, water use efficiency, transpiration rate, photoperiod-sensitive flowering time, and responses to glyphosate, gibberellic acid, and jasmonic acid. Phenotypes associated with the gene include hypocotyl elongation, seed germination, stomatal development, cold stress tolerance, and leaf longevity. Studies of related genes in other species link the family to flowering time, plant height, yield, and photosynthetic rate.
