ERF1 — Solanum lycopersicum

Summary

SlERF1 (SOLYC01G090340.3) on tomato chromosome 1 encodes a DNA-binding transcription factor of the AP2/ERF domain family, localised to the nucleus. The gene is associated with the regulation of ethylene-mediated signalling, pigment accumulation, and the biosynthesis of lutein, lycopene, cholesterol, nicotine, siderophores and polyamines. It is also linked to chlorophyll metabolism, the mevalonate pathway, acquisition of desiccation tolerance in seeds, sporulation, autotrophy, acid secretion, and secondary shoot formation. Associations with agronomic traits include fruit colour, fruit size, carotenoid content, net photosynthetic rate, transpiration rate, water use efficiency, stomatal resistance and seed maturation. Studies of related genes in other species connect the family to root fresh weight, fruit length and weight, plant height, heterosis, flavonoid content, seed viability, hydrogen peroxide content and salt response.
