CBF1 — Solanum lycopersicum

Summary

SOLYC03G026270.3 (CBF1) on tomato chromosome 3 encodes a DNA-binding transcription factor with AP2/ERF and DRE1A-I domains, and is associated with histone acetylase and transcription coactivator activities. The gene is linked to the upregulation of chlorophyll breakdown, wax anabolism, and strigolactone anabolism, as well as cellular responses to drought and salinity, glucose-mediated signalling, and positive regulation of leaf senescence. Associations include fruit firmness, starch content, proline content, photosynthetic rate, transpiration rate, germination rate, and responses to water stress, nitrate, cytokinin, auxin, and brassinosteroids. The gene is also connected to freezing tolerance, chilling injury, dehydration tolerance, disease resistance, biomass production, and cold acclimation. Related genes in other species link it to frost tolerance, drought stress tolerance, and enhanced freezing and salt stress tolerance.
