ERF1 — Solanum lycopersicum

Summary

SlERF1 (SOLYC05G051200.1) on tomato chromosome 5 encodes an AP2/ERF domain-containing transcription factor with DNA-binding and transcription coactivator activity. The gene is associated with TYLCV resistance and stress tolerance in tomato. It has been linked to cell wall organization, glucan and wax metabolism, ethylene metabolism, hormone signaling, and reactive oxygen species production. Associations include drought recovery, fruit firmness, fruit color and weight, carotenoid and glucose content, photosynthetic rate, water use efficiency, and abscisic acid and auxin content. The gene is also connected to disease resistance, pathogen defense, heat and salt tolerance, lateral root development, and stomatal aperture. Studies of related genes in other species link the family to ethylene response, GCC box-dependent transcription, and resistance to fungal and bacterial pathogens.
