CBF1 — Solanum tuberosum

Summary

PGSC0003DMG400014309, designated StCBF1 on potato chromosome 3, encodes a DNA-binding transcription factor of the AP2/ERF domain superfamily that also exhibits histone acetylase activity and transcription coactivator activity. In potato, the gene is associated with heat tolerance, and its annotated biological processes include cellular responses to drought and salinity, response to freezing, positive regulation of leaf senescence, upregulation of chlorophyll breakdown and wax anabolism, raffinose anabolism, ethylene anabolism, and glucose-mediated signalling. The gene has been linked to numerous agronomic traits including net photosynthetic rate, transpiration rate, subterranean shoot axis tuber size, leaf trichome density, anthocyanin content, jasmonic acid content, arsenic concentration, and responses to water stress, nitrate, cytokinin, auxin, brassinosteroids, and biotic stress. It localises to the nucleus, cytoplasm, and histone acetylase complex.
