Insect resistant, herbicide tolerant maize

The stacked maize line DAS-Ø15Ø7-1 x DAS-59122-7 x DAS-4Ø278-9 was obtained through the traditional cross breading of each of the parental organisms to produce a maize that expresses each of aryloxyalkanoate dioxygenase, Cry1F, PAT, Cry34Ab1 and Cry35Ab1 genes. The expression of these genes are expected to confer resistance to Lepidoptera and Coleoptera, and tolerant to 2,4-dichlorophenoxyacetic acid (2,4-D) and aryloxyphenoxypropionate (AOPP) acetyl coenzyme A carboxylase (ACCase) inhibitors and glufosinate herbicide.

DNA insert from TC1507 vector PHI8999A
The TC1507 line contained the Cry1F and PAT coding sequences and regulatory elements. The Cry1F gene produces insecticidal crystal protein that confers resistance against lepidopteran pests and the PAT gene produces Phosphinothricin N-acetyltransferase which confers tolerance to the glufosinate herbicide.

DNA insert from DAS40278 vector pDAS1740
DAS-40278-9 corn was modified with the insertion of a plant optimised coding sequence for aryloxyalkanoate dioxygenase to confer tolerance to the herbicides 2,4-dichlorophenoxyacetic acid (2,4-D) and aryloxyphenoxypropionate (AOPP) acetyl coenzyme A carboxylase (ACCase) inhibitors.

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.
