CBF1 — Solanum tuberosum

Summary

PGSC0003DMG400040222, symbol CBF1 on potato chromosome 11, encodes a dehydration-responsive element-binding protein 1B with an AP2/ERF domain and DNA-binding transcription factor activity, and is annotated with histone acetylase activity. The gene is associated with responses to cold, freezing, drought, and heat, and with positive regulation of leaf senescence, chlorophyll breakdown, wax and raffinose anabolism, ethylene anabolism, and glucose-mediated signalling. It has been linked to tuber size, net photosynthetic rate, transpiration rate, stomatal closure time, anthocyanin content, jasmonic acid content, trichome density, lateral root length, and sensitivities to cytokinin, auxin, brassinosteroid, nitrate, and osmotic stress. Studies of related genes in other species connect the CBF family to frost tolerance, drought tolerance, salinity tolerance, pathogen resistance, and photosynthetic capacity.
