Sugar beet line 77 was produced to exhibit tolerance to the herbicide glyphosate (Roundup) by incorporating the 5-enolpyruvylshikimate-3-phosphate synthase (cp4 epsps) gene from Agrobacterium sp. strain CP4 and a glyphosate oxidoreductase gene (gox) from Ochrobactrum anthropi.

Notes regarding the genetic elements introduced or modified in this LMO
Information on the inserted DNA sequences:
The codon optimised cp4epsps coding sequence cassette consists of the figwort mosaic virus (FMV) promoter, a chloroplast targeting sequence from Arabidosis thaliana, a CP4 EPSPS coding region from Agrobacterium sp. strain CP4. The CP4 EPSPS protein is highly resistant to inhibition by glyphosate, the active ingredient in Roundup herbicide.The uidA coding region for the B-D-glucuronidase (GUS) protein from E. coli and the 3' non-translated region from pea which directs polyadenylation. This gene serves as a selectable marker gene during the plant transformation process.The gox coding sequence cassette consists of the figworth mosaic virus (FMV) promoter, a chloroplast targeting sequence from Arabidosis thaliana promoter coding region from Ochrobactrum anthropi and the 3' non-translated region of  the nopaline synthase gene, which directs polyadenylation. When expressed, the function of the glyphosate oxidase (GOX) enzyme is to metabolize glyphosate (N-phosphonomethylglycine), the active ingredient in Roundup herbicide to an inactive form.

Vector information
The plasmid vector PV-BVGT03 contains well characterized DNA segments required for selection and replication of the plasmid in the bacteria as well as a right border for initiating the region of T-DNA, into the plant genomic DNA. The plasmids are composed of several genetic elements: cp4 epsps coding sequence from Agrobacterium tumefaciens, uid sequence (GUS) from Escherichi coli, gox sequence from Ochrobactrum anthropi, and nptII coding sequence from Tn5. The nptII gene was not transferred into the sugar beet genome because of the truncation of the insertion event within the gox gene. In addition, the plasmid contains a bacterial selectable marker coding sequence, aad as well as origins of replication (ori-V and ori-322) necessary for replication and maintenance of the plasmid PV-BVGT03 in bacteria.

The truncated nptII construct was as follows: CaMV 35S promoter >> nptII gene >> nos terminator

Additional information
Southern blot analysis indicates that a single copy of the epsps gene integrated into the host genome in addition to single copies of the gus and gox expression cassettes. However nuleotide sequencing analyses indicated that the gox coding sequence did not fully integrate into the host genome and is thus present in a truncated form. Protein expression analysis further indicated that the gox is expressed in a truncated, chimeric and incative form.
