ABI1 — Daucus carota subsp. sativus

Summary

DCAR_026404 (DcABI1) on carrot chromosome 7 encodes a protein with a PP2C domain and a PPM-type phosphatase-like domain, and is associated with sucrose-phosphate synthase activity, phase separation nucleator activity, and protein phosphatase regulator activity. This gene is linked to abscisic acid (ABA) mediated signaling, drought and salinity responses, and root structure development. It has been connected to traits including petal length, root system morphology, leaf elongation rate, biomass yield, seed viability, yield, and responses to water stress, submergence, and biotic stress. Associations also include regulation of actin polymerization, nectar secretion, cell shape, and potassium ion import. Related genes in other species are linked to ABA-regulated gene expression, ABA-mediated stomatal closure, heat tolerance, and defense response.
