Short description of the pLH vectors

1. Sfil A and B restriction sites

Oriented cloning of genes from pUC based vectors into binaries can be done with one restriction enzyme. The unique 8 base Sfil restriction site at the border of the MCS makes it possible to switch easily between different vectors with different plant selection markers.

2. PUC-based expression cassettes

Cloning of the genes can be easily done in pUC-based vectors with different orientation of the MCS and blue-white selection.

3. Selection marker at LB

The selection marker is located at the left border of the binary.

4. Reduced interference of promoter-fusion expression with the 35S-enhancer

The 35S promoter, which drives the selection marker is located close to the left border. Promoter-fusions with detectable markers (GUS,GFP) cloned into the MCS at the right border will have reduced enhancement of expression from the 35S-enhancer compared to other vectors (Cambia).

5. Plant-Selection-Markers: Neomycin, Hygromycin, Phosphinotricin (bar)

Beside nptll (pLH9000+pLH9500) there are also binaries available with bar (pLH7000+pLH7500) and hpt (pLH6000) as a selection marker. So a second and third transformation of the transgenic plant is possible with a different selection marker.

6. pVS1-Ori

The most exceptional feature of these vectors is the pVS1-ori which makes the binary more stable in Agrobacteria. This leds to a higher transformation rate compared to the pBin19 vector.

7. Bacterial selection marker: Streptomycin/Spectinomycin

For selection of plasmids in bacteria Streptomycin/Spectinomycin can be used.

8. ColE1-ori

The ColE1-ori allows elevated copy numbers in bacteria.
