Fig. 2From: Differential gene expression for carotenoid biosynthesis in a green alga Ulva prolifera based on transcriptome analysisCarotenoid biosynthetic pathway in plants and algae. Six enzymes participate in the steps of carotenoid biosynthesis. IPI: isopentenyl diphosphate isomerase; GGPS: geranylgeranyl diphosphate synthase; PSY: phytoene synthase; PDS: phytoene desaturase; ZDS: ζ-carotene desaturase; CRTL-B: lycopene b-cyclaseBack to article page
