CBF1 — Solanum tuberosum

Summary

PGSC0003DMG400014307 (StCBF1) on potato chromosome 3 encodes a CRT-binding factor 4 with DNA-binding transcription factor activity, histone acetylase activity, and transcription coactivator activity, and belongs to the DRE1A-I domain family. The gene is associated with responses to freezing, drought, salinity, and cytokinin, as well as positive regulation of leaf senescence, chlorophyll breakdown, wax and raffinose anabolism, ethylene biosynthesis, and glucose-mediated signalling. It localises to the nucleus, cytoplasm, and histone acetylase complex. StCBF1 is linked to tuber size, net photosynthetic rate, transpiration rate, stomatal closure time, anthocyanin content, lateral root length, leaf trichome density, and nitrate, auxin, and brassinosteroid sensitivity. Related genes in other species are associated with frost tolerance, drought resistance, and enhanced freezing, dehydration, and salt stress tolerance.
