CBF1 — Solanum tuberosum

Summary

PGSC0003DMG400014308, designated StCBF1 on potato chromosome 3, encodes a CRT binding factor 5 protein with DNA-binding transcription factor activity, histone acetylase activity, and transcription coactivator activity. The gene is associated with responses to freezing, drought, salinity, and heat tolerance, 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 numerous traits including tuber size, net photosynthetic rate, transpiration rate, anthocyanin content, lateral root length, leaf trichome density, and responses to water stress, nutrients, cytokinin, auxin, brassinosteroids, and biotic stress. Related genes in other species are associated with freezing, dehydration, salt, and drought tolerance, as well as photosynthetic capacity and pathogen resistance.
