The pGreen plasmid
Plasmid
In microbiology and genetics, a plasmid is a DNA molecule that is separate from, and can replicate independently of, the chromosomal DNA. They are double-stranded and, in many cases, circular...

s were first described in 2000. The supporting web page provides supplementary information and ongoing support to researchers to request their plasmid resources. As these plasmids have been taken up by the research community, the plasmids have been developed, expanding the resources available to the community.

Researchers are encouraged to contribute to this research community by submitting their vector sequence to genbank

The GenBank sequence database is an open access, annotated collection of all publicly available nucleotide sequences and their protein translations. This database is produced and maintained by the National Center for Biotechnology Information as part of the International Nucleotide Sequence...

 and providing a description of the plasmid on the site.

pGreenI and pGreenII

pGreen is the original pGreen plasmid.

pGreenII features plasmid backbone modification to improve plasmid stability.

No transformation selection

pGreenII 0000: minimal T-DNA with Left and Right border, Lac Z gene for blue/while selection during cloning multiple cloning site derived from pBluescript

pGreenII 62-SK: derived from pGreenII 0000, the LacZ blue/white cloning selection has been replaced with a 35S-MCS-CaMV cassette that allows the insertion of a gene of interest into a 35S over-expression cassette. The MCS is derived from pBluescript.

pGreenII 0800-LUC

Kanamycin selection

pGreenII 0029: derived from pGreenII 0000, a nos-kan cassette has been inserted into the HpaI site of the Left Border, providing resistance to kanamycin
Kanamycin
Kanamycin sulfate is an aminoglycoside antibiotic, available in oral, intravenous, and intramuscular forms, and used to treat a wide variety of infections. Kanamycin is isolated from Streptomyces kanamyceticus.-Mechanism:...

 during plant transformation selection.

pGreenII 0029 62-SK: derived from pGreenII 0029, the LacZ blue/white cloning selection has been replaced with a 35S-MCS-CaMV cassette that allows the insertion of a gene of interest into a 35S over-expression cassette. The MCS is derived from pBluescript.

Hygromycin selection

pGreenII 0179: derived from pGreenII 0000, a 35S-hyg cassette has been inserted into the HpaI site of the Left Border, providing resistance to hygromycin during plant transformation selection.

Bialaphos selection

pGreenII 0229: derived from pGreenII 0000, a nos-bar cassette has been inserted into the HpaI site of the Left Border, providing resistance to bialaphos or phosphinothricin during plant transformation selection.

pGreenII 0229 62-SK: derived from pGreenII 0229, the LacZ blue/white cloning selection has been replaced with a 35S-MCS-CaMV cassette that allows the insertion of a gene of interest into a 35S over-expression cassette. The MCS is derived from pBluescript.

pSoup

This is the helper plasmid that provides the replicase function for the pSa replication origin of pGreen. pSoup is tetracyclin resistant and a complementary incompatibility group such that it can co-exist with pGreen in the Agrobacterium

Agrobacterium is a genus of Gram-negative bacteria established by H. J. Conn that uses horizontal gene transfer to cause tumors in plants. Agrobacterium tumefaciens is the most commonly studied species in this genus...

cell.

pSoup: the original help plasmid for pSoup. pGreen will not replicate in Agrobacterium if it is not present.
