ABI1 — Daucus carota subsp. sativus

Summary

DCAR_018360 (DcABI1) on carrot chromosome 5 encodes a protein with a PP2C domain and is annotated with multiple molecular functions including protein phosphatase regulator activity, kinase regulator activity, and sucrose-phosphate synthase activity. The gene is associated with abscisic acid (ABA) signaling, drought response, and salinity response pathways. It is linked to numerous traits including root system morphology, petal length, leaf elongation rate, biomass yield, seed viability, yield, and responses to water stress, flooding, submergence, and various nutrient sensitivities. Associations also extend to lateral root development, root growth, dehydration tolerance, photosynthetic efficiency, and stomatal movement regulation. Related genes in other species link the family to ABA-mediated stomatal closure, heat tolerance, glucose tolerance, and defense responses.
