ACS1 — Beta vulgaris subsp. vulgaris

Summary

BvACS1 (BVRB_5G099920) on sugar beet chromosome 5 encodes a protein with 1-aminocyclopropane-1-carboxylate synthase activity and transaminase activity, and binds pyridoxal phosphate, protein kinase, phosphatase, calcium ion, ATP, and other proteins. The gene is associated with ethylene production and anabolism, as well as responses to ethylene, jasmonic acid, salt, freezing, cold acclimation, mechanical stimulus, and nutrient starvation (potassium, nitrogen, phosphate). It has been linked to regulation of abscisic acid-mediated signaling, stomatal movement, and phloem or xylem histogenesis. Associations with agronomic traits include seed yield, seed dormancy, leaf growth and senescence, root development and thickness, shoot branching, photosynthetic rate, respiration rate, anthocyanin content, nitrate uptake, and responses to waterlogging, hypoxia, cadmium, and Verticillium wilt. The protein localizes to the cytosol, plastid, mitochondria, plasma membrane, cell wall, vacuole, Golgi, and plasmodesmata.
