ERF3 — Solanum lycopersicum

Summary

SOLYC07G064890.1, designated ERF3 on tomato chromosome 7, encodes a DNA-binding transcription factor containing an AP2/ERF domain and is localized to the nucleus. The gene is associated with response to K+ ion, response to host, sensitization, fatty acid breakdown, protein metabolism, lycopene anabolism, hormone metabolism, histogenesis, autotrophy, carotenoid metabolism, brassinosteroid anabolism, abscisic acid anabolism, cell wall biogenesis, steroidogenesis, regulation of secondary shoot formation, and other biological processes. Trait associations include proline content, fruit shape, fruit size, sugar content, leaf size, plant height, drought tolerance, and salt tolerance. Related genes in other species, such as ABI4 and ERF4, are linked to the AP2/ERF family, though these roles are not yet established in tomato.
