Summary of Basic Genetic Modification

Gene Introduced Gene Source Product Function
cry1Fa2 synthetic form of cry1F gene derived from Bacillus thuringiensis var. aizawai modified Cry1F protein confers resistance to lepidopteran insects by selectively damaging their midgut lining
cp4 epsps (aroA:CP4) Agrobacterium tumefaciens strain CP4 herbicide tolerant form of 5-enolpyruvulshikimate-3-phosphate synthase (EPSPS) enzyme decreases binding affinity for glyphosate, thereby conferring increased tolerance to glyphosate herbicide
pat Streptomyces viridochromogenes phosphinothricin N-acetyltransferase (PAT) enzyme eliminates herbicidal activity of glufosinate (phosphinothricin) herbicides by acetylation
cry34Ab1 Bacillus thuringiensis strain PS149B1 Cry34Ab1 delta-endotoxin confers resistance to coleopteran insects particularly corn rootworm by selectively damaging their midgut lining
cry35Ab1 Bacillus thuringiensis strain PS149B1 Cry35Ab1 delta-endotoxin confers resistance to coleopteran insects particularly corn rootworm by selectively damaging their midgut lining
cry1Ab Bacillus thuringiensis subsp. kurstaki Cry1Ab delta-endotoxin confers resistance to lepidopteran insects by selectively damaging their midgut lining
mcry3A synthetic form of cry3A gene from Bacillus thuringiensis subsp. tenebrionis modified Cry3A delta-endotoxin confers resistance to coleopteran insects particularly corn rootworm pests by selectively damaging their midgut lining
pmi  * Escherichia coli Phosphomannose Isomerase (PMI) enzyme metabolizes mannose and allows positive selection for recovery of transformed plants
