CBF1 — Medicago truncatula

Summary

MTR_6G465690 (MtCBF1) on chromosome 6 of barrel medic encodes a DNA-binding transcription factor with an AP2/ERF domain and DRE1A-I family signature, also annotated with histone acetylase activity and transcription coactivator activity. The gene is associated with diverse biological processes including upregulation of chlorophyll breakdown, glucose-mediated signalling, cellular response to drought and salinity, positive regulation of leaf senescence, and upregulation of wax anabolism. It has been linked to traits such as leaf trichome density, water stress response, nitrate sensitivity, photosynthetic rate, transpiration rate, low temperature stress response, and anthocyanin content. Phenotypic associations include freezing tolerance, salt stress tolerance, cold acclimation, drought response, and stomatal development. Related genes in other species link the family to enhanced freezing, dehydration, and salt stress tolerance, as well as pathogen resistance and cold tolerance.
