GA21 maize

GA21 maize is one of Syngenta's Roundup Ready maizes. It was genetically engineered by particle acceleration (biolistic) transformation to be tolerant to glyphosate-containing herbicides (Roundup).
Through the transformation three complete copies of the m-epsps gene were inserted into the maize genome.
