CRTISO — Daucus carota subsp. sativus

Summary

DCAR_001700 (CRTISO-2, DcCRTISO) on carrot chromosome 1 encodes a CrtISO-like protein with amine oxidase and FAD/NAD-binding domains, annotated with carotenoid isomerase and redox activities. The gene is associated with carotenoid metabolism, pigmentation, carotenoid anabolism, and ABA signaling, and its product localizes to the chloroplast membrane and nucleus. Associations include root color, parasitic weed interactions, carotenoid content, and leaf carotenoid content. Studies of related genes in other species link the CRTISO family to carotene, lycopene, and anthocyanin content, photochemical quenching, drought tolerance, carotenoid accumulation, fruit color development, and lycopene biosynthesis.
