LMO name
Optimum™ GAT™ soybean
Transformation event
Unique identifier
Pioneer Hi-Bred International, Inc.
PO Box 1000
Johnston IA 50131-0184
The DP-356Ø43-5 modified soybean was produced by the insertion of modified glyphosate acetyltransferase (GAT4601) and acetolactate synthase (GM-HRA) genes.

Expression of the GAT4601 protein confers tolerance to glyphosate, and expression of the GM-HRA protein confers tolerance to acetolactate synthase-inhibiting herbicides such as sulfonylurea and imidazolinone herbicides.
Recipient Organism or Parental Organisms
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.

Further details
Notes regarding the genetic elements introduced or modified in this LMO
DP356043 contains the GAT4601 version of the glyphosate-N-acteyltransferase gene which results in tolerance to the glyphosate herbicide.

Southern blot analysis indicated that a single complete copy of the transformation cassette was integrated into the host genome with no  detectable integration of any segments of the vector backbone.
