CBF1 — Cucumis sativus

Summary

CSA_3G180260 (CBF1, also known as CsDREB1A, CsCBF1, FTQ4, and other synonyms) on cucumber chromosome 3 encodes a DNA-binding transcription factor with an AP2/ERF domain and is associated with histone acetylase activity and transcription coactivator activity. The gene is associated with responses to cold, drought, salinity, and osmotic stress, as well as to abscisic acid (ABA) and cytokinin signaling. It has been linked to chlorophyll breakdown, leaf senescence, sex determination, root morphogenesis, and vegetative phase change. Associations with agronomic traits include photosynthetic rate, transpiration rate, water stress response, nutrient response, flower and inflorescence development, trichome density, and tuber size. Studies of related genes in other species link the CBF/DREB family to freezing, chilling, drought, and salt tolerance, as well as to pathogen resistance and biomass production.
