CBF1 — Medicago truncatula

Summary

MTR_6G466000 (MtCBF1) on barrel medic chromosome 6 encodes a DREB1-type AP2/ERF domain-containing transcription factor with DNA-binding and transcription coactivator activities, and is also annotated with histone acetylase activity. The gene 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, seed germination, and secondary metabolism. It localises to the nucleus, cytoplasm and histone acetylase complex. MtCBF1 is associated with freezing tolerance, cold and drought stress responses, salt tolerance, dehydration tolerance, proline and soluble sugar accumulation, stomatal development, ABA response, and traits including leaf trichome density, photosynthetic rate, transpiration rate, lateral root length, anthocyanin content, and low temperature stress response.
