ERF1 — Solanum tuberosum

Summary

StERF1 (PGSC0003DMG400025989) on potato chromosome 1 encodes an AP2/ERF domain-containing transcription factor with sequence-specific DNA binding and transcription cis-regulatory region binding activity. It is associated with regulation of defense response, ethylene-mediated signaling, fruit ripening, circadian rhythm, cell cycle, pollen development, and asexual reproduction. The gene is linked to secondary metabolism, including the mevalonate, shikimate, and isoprenoid biosynthesis pathways, as well as cholesterol and steroid metabolism, carbohydrate metabolism, and virus-induced post-transcriptional gene silencing. It localizes to the nucleus and is associated with photosynthetic rate. Studies of related genes in other species connect the family to traits including root fresh weight, fruit size and color, carotenoid and flavonoid content, seed viability and maturation, plant height, water use efficiency, stomatal resistance, and salt response.
