ERF3 — Solanum lycopersicum

Summary

SlERF3 (SOLYC03G093560.1) encodes an AP2/ERF domain-containing transcription factor on tomato chromosome 3. The protein possesses sequence-specific DNA binding, DNA binding transcription factor activity, and protein kinase activity, and is localized to the nucleus, cytosol, and stress granules. SlERF3 is associated with TYLCV resistance in tomato, and with responses to oxygen levels, host interactions, and L-glutamate. It has been linked to fruit abscission, pollen-pistil interaction, microgametogenesis, and fruit firmness and color. Associations also include carbon isotope discrimination, selenium content, root fresh weight, shoot dry weight, net photosynthetic rate, transpiration rate, quantum yield, carotenoid content, proline content, and responses to UV-B light, jasmonic acid, and osmotic stress. Studies of related genes in other species link the family to cold and high light acclimation, herbivore and antiviral defense, nematode susceptibility, and cadmium tolerance.
