ABI1 — Daucus carota subsp. sativus

Summary

DCAR_011959 (DcABI1) on carrot chromosome 3 encodes a protein with a PP2C domain and a PPM-type phosphatase-like domain, and is associated with multiple molecular functions including sucrose-phosphate synthase activity, kinase regulator activity, and protein phosphatase binding. The gene is linked to abscisic acid (ABA) signaling, drought response, and salinity response pathways. It has been connected to numerous traits including root system morphology, petal length, leaf elongation rate, biomass yield, seed viability, and yield traits. Associations also include responses to water stress, submergence tolerance, nitrogen sensitivity, and biotic stress. The gene is linked to processes such as regulation of actin polymerization, nectar secretion, small GTPase-mediated signal transduction, and detection of nutrients. Related genes in other species link the family to ABA-regulated gene expression, stomatal closure, and heat tolerance.
