Herbicide tolerant Corn

GA21 x T25
Yes
MON-ØØØ21-9 × ACS-ZMØØ3-2
The stacked maize line MON-ØØØ21-9 x ACS-ZMØØ3-2 was obtained through the traditional cross breading of each of the parental organisms to produce a maize that expresses each of PAT and EPSPS genes. The expression of these genes are expected to confer tolerance to glufosinate and glyphosate herbicides.

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.

  • Cross breeding
Some of these genetic elements may be present as fragments or truncated forms. Please see notes below, where applicable.
DNA insert from ACS-ZMØØ3-2 vector pDH51
Glufosinate tolerance in T25 maize due to the enzyme phosphinothricin-N-acetyltransferase (PAT). The PAT enzyme catalyzes the acetylation of phosphinothricin, detoxifying it into an inactive compound. Molecular analyses shows that it has a truncated copy of the bla gene (25% of the 5' end of the bla gene is missing in T25) and an intact Ori-pUC.

DNA insert from GA21, vector pDPG434:
The GA21 line of maize was genetically engineered, by particle acceleration (biolistic) transformation, to be tolerant of glyphosate-containing herbicides.
