ACO1 — Solanum tuberosum

Summary

StACO1 (PGSC0003DMG400028951) on potato chromosome 7 encodes an aconitase, a 4Fe-4S cluster-containing enzyme with intramolecular hydroxytransferase and 3-isopropylmalate dehydratase activities. It is associated with the TCA cycle, glyoxylate cycle, citrate and isocitrate metabolism, and ethylene anabolism. The gene is linked to regulation of salicylic acid-mediated signaling, negative regulation of leaf senescence, trichome morphogenesis, and response to iron ion starvation. Associations with traits include seed volume and size, protein content, ethylene sensitivity, stomatal opening, and root morphology. Phenotypic connections include lateral root development, gravitropic response, salt tolerance, and waterlogging stress tolerance. The protein localizes to mitochondria, chloroplast stroma, plastids, cytosol, plasmalemma, and plasmodesmata. Studies of related genes in other species link the family to seed germination, stress response, and ethylene biosynthesis.
