EIL1 — Solanum lycopersicum

Summary

SOLYC01G009170.4, the tomato EIL1 (also known as SlEIN3 or EIN3) gene on chromosome 1, encodes an ethylene-insensitive 3-like DNA-binding domain-containing protein with sequence-specific DNA binding, chromatin binding, and histone deacetylase activity. It is associated with ethylene metabolism, lycopene and carotenoid metabolism, regulation of defense responses to insects and wounding, iron transport, sex determination, petal morphogenesis, dehiscence, and organ growth. The gene is linked to numerous agronomic traits including fruit firmness, color, shape, and size, seed protein content, carotenoid content, iron sensitivity and concentration, phosphorus response, shoot elongation under submergence, branch angle, and lignin biosynthesis. It localizes to the nucleus, cytoplasm, chloroplast envelope, and SCF and Sin3-type complexes. Studies of related genes in other species connect the family to iron efficiency, flowering time, and resistance to fungal pathogens and herbivory.
