Insect resistant, herbicide tolerant maize

SYN-BTØ11-1 × DAS-59122-7 × MON-ØØØ21-9
A stacked insect-resistant and herbicide-tolerant maize derived from conventional cross-breeding of BT11 x DAS-59122 x GA21.  Insect resistance is conferred by the cry1A(b), cry34Ab1, and cry35Ab1 genes from the common soil bacterium Bacillus thuringiensis, and glufosinate and glyphosate herbicide tolerance through the pat and EPSPS genes respectively.

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.

Characteristics of the modification process

EN
  • Cross breeding
Some of these genetic elements may be present as fragments or truncated forms. Please see notes below, where applicable.
DNA insert from Bt11 vector pZO1502
Contributed the cry1Ab gene to confer resistance to the European corn borer (Ostrinia nubilalis), and the phosphinothricin N-acetyltransferase (PAT) encoding gene  to confer tolerance to phosphinothricin (PPT) herbicide, specifically glufosinate ammonium.

DNA insert from GA21 vector pDPG434
The 5-enolpyruvyl shikimate-3-phosphate synthase (epsps) gene from maize was modified through site-directed mutagenesis, such that its encoded enzyme was insensitive to inactivation by glyphosate. The resulting gene was used to develop GA21

DNA insert from 59122 vector PHP17662
The cry34Ab1 and cry35Ab1 genes, isolated from the common soil bacterium Bacillus thuringiensis (Bt) strain PS149B1, produce the insect control proteins (delta-endotoxins) Cry34Ab1 and Cry35Ab1. The pat gene was isolated from the soil bacterium Streptomyces viridochromogenes and confers tolerance to herbicides containing glufosinate ammonium.
