CBF1 — Camelina sativa

Summary

CsCBF1 (CSA18975S010) encodes a DNA-binding transcription factor with an AP2/ERF domain, also annotated with histone acetylase activity and transcription coactivator activity. In Camelina sativa, CsCBF1 is associated with the upregulation of chlorophyll breakdown and wax anabolism, positive regulation of leaf senescence, cellular responses to drought and salinity, glucose-mediated signalling, root morphogenesis, and responses to auxin, cytokinin, and light. It localises to the nucleus and histone acetylase complex. The gene is linked to traits including freezing tolerance, cold acclimation, salt stress tolerance, dehydration response, biomass production, disease resistance, and somatic embryogenesis. Additional associations include photosynthetic rate, transpiration rate, proline content, anthocyanin content, and responses to osmotic stress, brassinosteroids, and jasmonic acid. Studies of related genes in other species connect the family to enhanced freezing, dehydration, and salt stress tolerance, as well as drought and heat tolerance.
