ERF1 — Solanum lycopersicum

Summary

SlERF1 (SOLYC09G089930.3) on tomato chromosome 9 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 diverse biological processes including glucan and lycopene anabolism, chlorophyll metabolism, cytokinin anabolism, polyamine metabolism, downregulation of photosynthesis, phloem unloading, and responses to herbivores and stimuli. Associations with traits include growth hormone content, fruit color and size, carotenoid and chlorophyll content, net photosynthetic rate, water use efficiency, ethylene and auxin sensitivity, flowering time, leaf chlorosis and curling, root morphology, and disease tolerance. The gene is also associated with pathogen resistance, including resistance to Botrytis cinerea, salt and drought tolerance, heat tolerance, lateral root development, and jasmonic acid signaling.
