Basic Genetic Modification

Gene Introduced Gene Source Product Function
crt1 Pantoea ananatis phytoene desaturase enzyme CRTI catalyzes the conversion of 15-cis-phytoene to all-trans-lycopene
psy1 Zea mays phytoene synthase ZmPSY1 converts geranylgeranyl diphosphate into phytoene, and acts upstream of CRTI in the carotenoid biosynthesis pathway
pmi  * Escherichia coli Phosphomannose Isomerase (PMI) enzyme metabolizes mannose and allows positive selection for recovery of transformed plants
