ERF5 — Solanum lycopersicum

Summary

SOLYC05G052030.1, also known as ERF5 or SlERF5, encodes an AP2/ERF domain-containing transcription factor that localises to the nucleus and binds sequence-specific DNA. In tomato, this gene is associated with the downregulation of wax anabolism, cutin anabolism, and chlorophyll a breakdown, as well as with pigment accumulation, carotenoid metabolism, and fruit and leaf abscission. It has been linked to agronomically important traits including fruit size, carotenoid content, ethylene sensitivity, stomatal resistance, and carbon isotope discrimination. Associations with drought tolerance, resistance to Botrytis cinerea and Pseudomonas syringae, and UV-B stress tolerance have also been observed. Studies of related genes in other species connect the ERF5 family to wax biosynthesis, cuticle formation, freezing tolerance, and anthocyanin biosynthesis.
