ACS1 — Cucumis melo

Summary

MELO3C016340.2 (CmACS1) on melon chromosome 8 encodes a 1-aminocyclopropane-1-carboxylate (ACC) synthase, a pyridoxal phosphate-dependent enzyme with 1-aminocyclopropane-1-carboxylate synthase activity. The gene is associated with ethylene production and sensitivity, fruit development, carpel and stamen development, and phloem or xylem histogenesis. It is linked to responses to freezing, cold acclimation, mechanical stimulus, and nutrient starvation (nitrogen, phosphate, potassium). Associations also include vegetative vigor, leaf length, shoot growth angle, root development, seed yield and dormancy, photosynthetic rate, stomatal resistance, anthocyanin content, and resistance to biotic stresses such as powdery mildew and Verticillium wilt. The gene is connected to pistil morphology, female flower development, lateral root formation, auxin response, and waterlogging, salt, cadmium, and iron deficiency stress responses.
