ABI1 — Daucus carota subsp. sativus

Summary

DCAR_004392 (DcABI1) on carrot chromosome 1 encodes a protein with PP2C and PPM-type phosphatase domains and has been annotated with sucrose-phosphate synthase activity, phase separation nucleator activity, and multiple phosphatase regulator and binding functions. The gene is associated with abscisic acid (ABA) mediated signaling, drought and salinity responses, root structure development, and nectar secretion. It is linked to traits including petal length, root system morphology, leaf elongation rate, biomass yield, seed viability, yield, submergence tolerance, and responses to water stress, light quality, and various nutrient sensitivities. Associations also include lateral root development, root growth, dehydration tolerance, photosynthetic efficiency, stomatal closure, and cadmium tolerance. Studies of related genes in other species link the family to ABA-regulated gene expression, ABA-mediated stomatal closure, heat tolerance, glucose tolerance, and defense response.
