WORK IN PROGRESS




PVX201 (which contains a DNA copy of the Potato Virus X genome with a duplicated sub-genomic promoter) and pGR107 (PVX-based expression vector designed to combine the advantages of the A. tumefaciens-mediated transfection strategy and the infection power of the PVX virus) vectors were kindly provided from Prof. David Baulcombe (The Sainsbury Laboratory, Norwich, UK) and PBL - Innovation in Life Sciences (http://www.pbltechnology.com).

pG PVX 6His

The PVX201 vector (kindly provided by David Baulcombe, The Sainsbury Laboratory, Norwich, UK) containing the PVX cDNA under the transcriptional control of the Cauliflower 35S promoter and the nopaline synthase terminator was ligated to the 2A double stranded oligolinker and then ligated to the 6His-tag oligolinker to produce the PVX6His2ACP vector. This vector contains a unique SalI site to be used for cloning coding sequences for the gene of interest that is fused in frame to the 3 terminus of the 6His-tag and to the 5 end of the 2A sequence.
