Description
The 98140 maize has been genetically modified (GM) to express the GAT4621 and ZM-HRA proteins. The GAT4621 protein is a glyphosate acetyltransferase (GAT), encoded by an optimized form of the gat gene from Bacillus licheniformis. When cultivated, expression of the GAT4621 protein in 98140 maize confers tolerance to the herbicide glyphosate. The ZM-HRA protein is an acetolactate synthase (ALS) encoded by the zm-hra gene, an optimized form of the endogenous als gene from Zea mays. When cultivated, expression of the ZM-HRA protein in 98140 maize confers tolerance to ALS-inhibiting herbicides, such as chlorimuron and thifensulfuron.
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.

Notes regarding the genetic elements introduced or modified in this LMO
For transformation of 98140 maize, binary vector PHP24279 was used. The between the left and right border repeats, the inserted T-DNA consists of a 7440 bp sequence contains, in addition to the genetic elements listed above:

Three copies of the CaMV 35S enhancer region from cauliflower mosaic virus between the promoters of the two expression casettes which contribute to enhance expression of both the gat4621 and zm-hra genes.
