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 |
* : Selection Marker/Reporter
