Maize 1507 x 59122


Trait: This maize hybrid confers insect resistant and herbicide tolerant derived from conventional cross-breeding of the parental lines 1507 and 59122.
Inserted genes (1507):
cryIF-gene

Source: Bacillus thuringiensis kurstaki

Function: The gene codes for a Bt-toxin, which protects the plant against the european corn borer (Ostrinia nubilalis) and other lepidopterans such as the pink borer (Sesamia spp.), fall armyworm (Spodoptera frugiperda), black cutworm (Agrotis ipsilon) and southwestern corn borer (Diatraea grandiosella).

Inserted genes (59122):
cry34Ab1, cry35Ab1-gene

Source: Bacillus thuringiensis ssp. kumamotoensis

Function: The genes code for Bt-toxins, which protect the plant against Coleopteran insects, such as western corn rootworm (Diabrotica virgifera), northern corn rootworm (D. barberi), and mexican corn rootworm (D. virgifera zeae).

pat-gene This gene is also used as a marker gene.

Function: The gene expressed the enzyme which produces Phosphinothricin-Acetyltransferase (PAT) and increased tolerance to the herbicide glufosinate-ammonium.

Methods for the genetic modification: Microparticle bombardment of plant cells tissue
