PGreen

PGreen

The pGreen plasmids were first described in 2000 [ [http://www.springerlink.com/content/p264110437m2k479 "pGreen: a versatile and flexible binary Ti vector for Agrobacterium-mediated plant transformation,"] "Plant Molecular Biology" 42: 819-832, 2000] . The supporting web page [ [http://www.pGreen.ac.uk www.pGreen.ac.uk] ] 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 and providing a description of the plasmid on the site.

pGreenI and pGreenII

[http://www.ncbi.nlm.nih.gov/entrez/viewer.fcgi?db=nuccore&id=3402815 pGreen] is the original pGreen plasmid.

[http://www.ncbi.nlm.nih.gov/entrez/viewer.fcgi?db=nuccore&id=146742365 pGreenII] features plasmid backbone modification to improve plasmid stability (review manuscript in preparation).

T-DNA regions

No transformation selection

[http://www.ncbi.nlm.nih.gov/sites/entrez?term=EU048862&cmd=Search&db=nuccore&QueryKey=1 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 [http://www.ncbi.nlm.nih.gov/sites/entrez?term=EU048868&cmd=Search&db=nuccore&QueryKey=1 pGreenII 62-SK] : derived from pGreenII 0000, the "Lac"Z 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.

Kanamycin selection

[http://www.ncbi.nlm.nih.gov/sites/entrez?term=EU048864&cmd=Search&db=nuccore&QueryKey=1 pGreenII 0029] : derived from pGreenII 0000, a nos-kan cassette has been inserted into the "Hpa"I site of the Left Border, providing resistance to kanamycin during plant transformation selection.

[http://www.ncbi.nlm.nih.gov/sites/entrez?term=EU048865&cmd=Search&db=nuccore&QueryKey=1 pGreenII 0029 62-SK] : derived from pGreenII 0029, the "Lac"Z 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

[http://www.ncbi.nlm.nih.gov/sites/entrez?term=EU048866&cmd=Search&db=nuccore&QueryKey=1 pGreenII 0179] : derived from pGreenII 0000, a 35S-hyg cassette has been inserted into the "Hpa"I site of the Left Border, providing resistance to hygromycin during plant transformation selection.

Bialaphos selection

[http://www.ncbi.nlm.nih.gov/sites/entrez?term=EU048867&cmd=Search&db=nuccore&QueryKey=1 pGreenII 0229] : derived from pGreenII 0000, a nos-bar cassette has been inserted into the "Hpa"I site of the Left Border, providing resistance to bialaphos or phosphinothricin during plant transformation selection.

[http://www.ncbi.nlm.nih.gov/sites/entrez?term=EU048869&cmd=Search&db=nuccore&QueryKey=1 pGreenII 0229 62-SK] : derived from pGreenII 0229, the "Lac"Z 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" cell.

[http://www.ncbi.nlm.nih.gov/sites/entrez?term=EU048870&cmd=Search&db=nuccore&QueryKey=1 pSoup] : the original help plasmid for pSoup. pGreen will not replicate in "Agrobacterium" if it is not present.
