ACC4 — Triticum aestivum

Summary

TaACC4 (TRAESCS4D02G058200) on wheat chromosome 4D encodes a 1-aminocyclopropane-1-carboxylate synthase (EC 4.4.1.14) and also carries domains associated with aminotransferase and pyridoxal phosphate-binding activities. The gene is associated with regulation of ethylene biosynthetic process, negative regulation of ethylene biosynthetic process, response to organophosphorus, response to K+ ion, cellular response to K+ ion starvation, cellular response to nitrogen starvation, and response to freezing. It is linked to traits including yield, fruit ripening, leaf growth and development, leaf senescence, root hair length, lateral root number, root mass density, stem rust, bacterial disease response, low temperature stress response, and arsenic concentration. Localisation evidence connects the encoded protein to the plant-type cell wall, plant-type vacuole, Golgi complex, plasmodesma, plastid, mitochondria, cytosol, and plasmalemma. Studies of related genes in other species link the ACC synthase family to ethylene production, root and shoot development, flowering time, and stress tolerance.
