CBF1 — Solanum lycopersicum

Summary

SlCBF1 (SOLYC03G026280.3) on tomato chromosome 3 encodes a DNA-binding transcription factor with an AP2/ERF domain, also annotated with histone acetylase activity and transcription coactivator activity. It is associated with diverse biological processes including cellular response to drought, upregulation of chlorophyll breakdown, strigolactone anabolism, glucose-mediated signalling, and stomatal opening. The gene is linked to numerous agronomic traits such as fruit firmness and size, sugar and starch content, photosynthetic ability, net photosynthetic rate, water use efficiency, transpiration rate, proline content, leaf trichome density, stem diameter, and responses to water stress, nitrate, cytokinin, auxin, brassinosteroids, light intensity, osmotic stress, and insect damage. Phenotypic associations include freezing tolerance, postharvest chilling injury, dehydration tolerance, cold acclimation, drought adaptation, disease resistance, and somatic embryogenesis. Related genes in other species are linked to frost tolerance, cold and drought stress tolerance, and enhanced freezing, dehydration, and salt stress tolerance.
