LMO name
Liberty Link™ rice
Transformation event
Unique identifier
Bayer CropScience (Aventis CropScience (AgrEvo))
Bayer CropScience AG
Alfred-Nobel-Str. 50
Monheim am Rhein
Rice resistant to the herbicide glufosinate through introduction of the bar gene from Streptomyces hygroscopicus which encodes the enzyme phosphinothricin-N-acetyltransferase (PAT) that catalyzes the acetylation of phosphinothricin (glufosinate), detoxifying it into an inactive compound.
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.
Oryza sativa - Rice, ORYSA
Point of collection or acquisition of the recipient organism
Variety: Cocodrie

Notes regarding the genetic elements introduced or modified in this LMO
The phosphinothricin-N-acetyltransferase enzyme coding sequence was obtained from the Streptomyces hygroscopicus HP632 strain. the The 2 N-terminal codons of the wild type gene were modified to an ATG and GAC respectively.

Southern blot analysis indicated the presence of a single bar gene flanked its regulatory genetic elements. further analysis indicated the the 3' nos terminator was truncated during the transformation process. Additionally a second copy of the 35S promoter or part of it was inserted into the host genome.

Bioinformatic analysis by the company of the regions flanking the bar gene suggests that no known rice gene was interrupted and that no chimeric proteins would be expressed due to the gene insertion. Such an analysis was not performed for the second insertion containing 35S promoter sequences.
