CBF1 — Arabidopsis thaliana

Summary

AT4G25490, known as CBF1 or DREB1B, encodes a transcription factor with an AP2/ERF DNA-binding domain and histone acetylase activity. It is associated with water deficit resistance, chilling stress tolerance, biotic stress resistance, oxidative stress tolerance, low temperature tolerance, and transcriptional regulation. The gene has been connected to the regulation of raffinose, strigolactone, melatonin, glucosinolate, and salicylic acid biosynthesis, along with gibberellin and ethylene metabolism. It is linked to traits including biomass yield, photosynthetic ability, proline content, stamen number, leaf trichome density, and tuber size. Studies of related CBF family members in other species associate the family with cold tolerance, tuber induction, and antioxidant defence.
