Characterization of 15-cis-ζ-Carotene Isomerase Z-ISO in Cultivated and Wild Tomato Species Differing in Ripe Fruit Pigmentation.

ABSTRACT: Isomerization of 9,15,9'-tri-cis-ζ-carotene mediated by 15-cis-ζ-carotene isomerase Z-ISO is a critical step in the biosynthesis of carotenoids, which define fruit color. The tomato clade (Solanum section Lycopersicon) comprises the cultivated tomato (Solanum lycopersicum) and 12 related wild species differing in fruit color and, thus, represents a good model for studying carotenogenesis in fleshy fruit. In this study, we identified homologous Z-ISO genes, including 5'-UTRs and promoter regions, in 12 S. lycopersicum cultivars and 5 wild tomato species (red-fruited Solanum pimpinellifolium, yellow-fruited Solanum cheesmaniae, and green-fruited Solanum chilense, Solanum habrochaites, and Solanum pennellii).
