Gene Introduced Gene Source Product Function
prsv_cp Papaya ringspot virus (PRSV) coat protein (CP) of the papaya ringspot virus (PRSV) confers resistance to papaya ringspot virus (PRSV) through "pathogen-derived resistance" mechanism
nptII  * Escherichia coli Tn5 transposon neomycin phosphotransferase II enzyme allows transformed plants to metabolize neomycin and kanamycin antibiotics during selection
uidA  * Escherichia coli beta-D-glucuronidase¬†(GUS) enzyme produces blue stain on treated transformed tissue, which allows visual selection
 * : Selection Marker/Reporter
