EIN3 — Solanum lycopersicum

Summary

SlEIN3 (SOLYC01G096810.3) on tomato chromosome 1 encodes a protein with an EIN3-like DNA-binding domain, placing it in the ethylene-insensitive3-like family. The gene is associated with regulation of the ethylene-mediated signaling pathway, sex determination, abscission, organ growth, photoprotection, carotenoid metabolism, lycopene and auxin anabolism, chlorophyll breakdown, sulfate assimilation, RNA methylation, and regulation of response to wounding. Associations with traits include fruit color, shape, size, and carotenoid content, as well as stem diameter, plant height, sugar content, ethylene sensitivity, and oxidative stress response. The encoded protein localizes to the nucleus. Studies of related genes in other species link the family to root hair density and length.
