Summary of Basic Genetic Modification

Gene Introduced	Gene Source	Product	Function
cry1Ac	Bacillus thuringiensis subsp. Kurstaki strain HD73	Cry1Ac delta-endotoxin	confers resistance to lepidopteran insects by selectively damaging their midgut lining
API	Sagittaria sagittifolia (arrowhead)	arrowhead protease inhibitor protein A or B	confers resistance to a wide range of insect pests
nptII  *	Escherichia coli Tn5 transposon	neomycin phosphotransferase II enzyme	allows transformed plants to metabolize neomycin and kanamycin antibiotics during selection

 * : Selection Marker/Reporter
