ERF1 — Solanum tuberosum

Summary

PGSC0003DMG400010750 (ERF1) on potato chromosome 3 encodes an AP2/ERF domain-containing protein with DNA-binding transcription factor activity. The gene is associated with a wide range of biological processes, including regulation of ethylene-mediated signaling, induction of programmed cell death, wound healing, and induced systemic resistance. It has been linked to regulation of flavonoid, carotenoid, starch, and sterol anabolism, as well as the mevalonate pathway and phytoalexin biosynthesis. ERF1 is also associated with traits such as starch and sugar content, photosynthetic rate, anthocyanin content, drought tolerance, and salt tolerance. Phenotypic associations include nematode resistance, insect herbivory resistance, phenolics accumulation, and ethylene response. The protein localizes to the nucleus and protoplasm. Studies of related genes in other species link the ERF family to additional traits including bacterial blight resistance, fruit characteristics, and heat stress tolerance.
