CBF1 — Camelina sativa

Summary

CsCBF1 (CSA10G017480) on Camelina sativa chromosome 10 encodes a DNA-binding transcription factor with an AP2/ERF domain and histone acetylase activity, localizing to the nucleus as part of a histone acetylase complex. It is associated with upregulation of chlorophyll breakdown and wax anabolism, positive regulation of leaf senescence, and responses to drought, salinity, osmotic stress, cytokinin, auxin, and light. The gene is linked to freezing tolerance, cold acclimation, and abiotic stress tolerance, as well as traits including subterranean shoot axis tuber size, water stress response, leaf trichome density, proline content, photosynthetic rate, transpiration rate, and nitrate sensitivity. Related genes in other species are associated with enhanced freezing, dehydration, and salt stress tolerance, frost tolerance, and drought stress resistance.
