ACS1 — Solanum tuberosum

Summary

PGSC0003DMG400005825, also known as ACS1, PPACS1, or StACS1, encodes a 1-aminocyclopropane-1-carboxylate synthase on potato chromosome 8, an enzyme with 1-aminocyclopropane-1-carboxylate synthase activity (EC 4.4.1.14) that also exhibits transaminase, pyridoxal phosphate binding, protein kinase binding, and phosphatase activities. The gene is associated with pre-harvest sprouting, biological regulation, response to stimulus, nitrogen fixation, wound healing, sucrose and starch anabolism and breakdown, abscisic acid anabolism, and cellular responses to potassium and nitrogen starvation. It has been linked to numerous agronomic traits including starch yield and content, seed yield, drought sensitivity, photosynthetic rate, ethylene sensitivity, anthocyanin content, leaflet number, vegetative vigor, shoot branching, stem elongation, and resistance to Verticillium wilt. The protein localizes to the cytosol, plastid, mitochondria, plasmalemma, plant-type cell wall, vacuole, Golgi, and plasmodesmata.
