Description
The genetically modified maize has an altered growth characteristic resulting from the introduction of a Gibberelin 20 Oxidase-1 gene from Arabidopsis thaliana. The plants become significantly longer without producing significantly more biomass.

Additionally the bar-gene from Streptomyces hygroscopicus is present in the plant as a selection marker gene. This bar-gene produces the Phosphinotricin Acetyl Transferase enzyme (PAT), which acetylates phosphinotricin, also known as glufosinate, the active ingredient of herbicides such as Basta and Liberty.
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.
