Summary of Basic Genetic Modification

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  

Summary of Regulatory Approvals: Country, Year and Type of Approval

Country	Food direct use or processing	Feed direct use or processing	Cultivation domestic or non-domestic use
United States
