ACS1 — Daucus carota subsp. sativus

Summary

DcACS1 (DCAR_008637) on carrot chromosome 2 encodes a protein with 1-aminocyclopropane-1-carboxylate synthase activity, transaminase activity, phosphatase activity, and protein kinase binding activity. The gene is associated with ethylene production, ACC accumulation, and responses to ethylene, jasmonic acid, oxidative stress, and mechanical stimuli. It is linked to cold acclimation, freezing response, and regulation of abscisic acid-mediated signaling. DcACS1 has been connected to numerous agronomic traits including seed yield, seed dormancy, leaf senescence, vegetative vigor, root development, shoot branching, stomatal movement, photosynthetic rate, anthocyanin content, and responses to waterlogging, salt stress, cadmium, hypoxia, and Verticillium wilt. It is also associated with pistil morphology, female flower development, lycopene content, and nematode resistance. The protein localizes to the cytosol, plastid, mitochondria, plasmalemma, and plasmodesmata.
