Description
Maize resistant to European corn borer (Ostrinia nubilalis) through introduction of a synthetic cry1Ab gene. Also tolerant to the glyphosate herbicide via introduction of the bacterial version of the epsps gene encoding a plant enzyme, 5-enolpyruvyl shikimate-3-phosphate synthase (EPSPS) and glyphosate oxidoreductase (gox).
Recipient Organism or Parental Organisms
The term Recipient organism refers to an organism (either already modified or non-modified) that was subjected to genetic modification, whereas Parental organisms refers to those that were involved in cross breeding or cell fusion.

Further details
Notes regarding the genetic elements introduced or modified in this LMO
The PV-ZMBK07 plasmid contained the coding sequence of a synthetic version of the cry1Ab gene from Bacillus thuringiensis, which was modified to enhance the expression of the Cry1Ab protein in plants, however the resulting amino acid sequence is identical to the native protein.

PV-ZMGT10 plasmid contained the genes cp4 epsps and gox as well as the antibiotic resistance marker gene nptII.

Southern blot analysis indicated that MON809 contains one full and one partial copy of the Cry1Ab coding sequence, two full copies of the EPSPS coding sequence and one partial copy of the gox gene sequence. Furthermore analysis indicated that portions of the phosphate backbone containing nptII and ori-pUC19 were also integrated into the host genome.

Additional Information
Additional Information
The transgenic maize line MON809 was genetically engineered to resist ECB by producing its own insecticide. This line was developed by introducing the cry1Ab gene. Cry proteins, of which Cry1Ab is only one, act by selectively binding to specific sites localized on the lining of the midgut of susceptible insect species. Following binding, pores are formed that disrupt midgut ion flow, causing gut paralysis and eventual death due to bacterial sepsis. Cry1Ab is lethal only when eaten by the larvae of lepidopteran insects (moths and butterflies), and its specificity of action is directly attributable to the presence of specific binding sites in the target insects.
