ERF1 — Solanum lycopersicum

Summary

SOLYC05G052050.1 (ERF1) on tomato chromosome 5 encodes an AP2/ERF domain-containing transcription factor with DNA-binding and transcription-regulatory activity. In tomato, ERF1 is associated with bacterial leaf spot resistance and heat stress tolerance. The gene is linked to a wide range of processes including ethylene signaling, lycopene and chlorophyll metabolism, wax metabolism, and seed morphogenesis. Associations with agronomically important traits include fruit firmness, fruit color and size, carotenoid and flavonoid content, net photosynthetic rate, water use efficiency, and bacterial blight disease resistance. ERF1 is also connected to nematode resistance, herbivory defense, and ethylene response. Studies of related genes in other species link the family to abscisic acid sensitivity, cadmium tolerance, and lateral root emergence.
