CRTISO — Solanum lycopersicum

Summary

SlCRTISO (SOLYC02G085250.4) on tomato chromosome 2 encodes a protein with carotenoid isomerase activity, copper binding and redox activity, belonging to the amine oxidase domain and FAD/NAD-binding superfamily. It is associated with apocarotenoid anabolism, carotene anabolism, lycopene anabolism, carotenoid metabolism, isoprenoid metabolism, flavonoid metabolism, chlorophyll breakdown, pigmentation, fruit color, lycopene content, carotenoid content, anthocyanin content and drought tolerance. The protein localises to the chloroplast membrane, plastid and mitochondria. Studies of related genes in other species link the CRTISO family to carotene content, fruit flesh color and fruit aroma.
