CBF1 — Solanum lycopersicum

Summary

SlCBF1 (SOLYC03G124110.2) on tomato chromosome 3 encodes a DNA-binding transcription factor with an AP2/ERF domain, also annotated for histone acetylase activity and transcription coactivator activity. It is associated with diverse biological processes including cellular response to drought, upregulation of chlorophyll breakdown and wax anabolism, strigolactone and nicotine anabolism, glucose-mediated signalling, stomatal opening, and cell redox homeostasis. The gene is linked to numerous agronomic traits such as fruit firmness, phosphorus and starch content, proline content, quantum yield, transpiration rate, germination rate, lateral root length, leaf trichome density, and responses to water stress, nitrate, cytokinin, auxin, brassinosteroids, osmotic stress, light intensity, insects, and biotic stress. Phenotypic associations include freezing tolerance, chilling injury, dehydration tolerance, disease resistance, biomass production, and cold acclimation.
