Maize MON89034xMON88017


Trait: This maize hybrid confers insect resistance and herbicide tolerance derived from conventional cross-breeding of the parental lines MON89034 and MON88017.
Inserted genes (MON89034):
cry1A.105 and
cry2Ab2

Source: Bacillus thuringiensis 

Function: The toxins protects the plant from the Lepidopteran insects, fall armyworm (Spodoptera sp.), black cutworm (Agrotis ipsilon), european corn borer(Ostrinia nubilalis) and the corn earworm (Helicoverpa zea).

Inserted genes (MON88017):
cry3Bb1-genes

Source: Bacillus thuringiensis ssp. kumamotoensis

Function: The toxin protects the plant from the Coleopteran insects western corn rootworm (Diabrotica virgifera), northern corn rootworm (D. barberi), and Mexican corn rootworm (D. virgifera zeae).

cp4 epsps- gene

Source: Soil bacterium Agrobacterium ssp. strain CP4

Function: The CP4 EPSPS gene encodes for a version of EPSPS Enzyme that is highly tolerant to inhibition by glyphosate.

Methods for the genetic modification: Agrobacterium tumefaciens-mediated gene transfer.
