Sugarbeet modified for herbicide tolerance
Sugarbeets were modified to constitutively express a synthetic phosphinothricin acetyltransferase (pat) gene. As a result of the genetic modification the resulting sugarbeet is tolerant to L-phosphinothricin-containing herbicides.
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.

Characteristics of the modification process
  • Agrobacterium-mediated DNA transfer
Some of these genetic elements may be present as fragments or truncated forms. Please see notes below, where applicable.
The amino acid sequence of the pat gene is based on the pat gene from Streptomyces viridochromogenes but was codon optimized for expression in sugarbeet.

The following elements of the vector piAn7 were also transferred but are not expressed and are non-functional in sugarbeet:

*The cos-site of bacteriophage Lambda;
*The ori of pBR322; and
*The SupF t-RNA gene of E. coli.
