By simple infiltration of Agrobacterium cells carrying appropriate gene constructs into tobacco plants leaves, transient expression assays can be performed within 3 days without using expensive instruments or complicated procedures. Two days after agroinfiltration, expression and subcellular localization of the GFP fusion proteins in tobacco leaves can be determined by simple observation under fluorescence or confocal laser scanning microscopy. 7. Generate plasmid pCV12 (Fig. 1 ) or similar nuclear transformation vector for expression of a fusion protein consisting of the SARS-CoV S1 and GFP. Production of tobacco leaves transiently expressing a protein fusion consisting of the SARS-CoV S1 protein fused with the GFP was carried out using Agrobacterium-mediated transformation with plasmid pCV12. ./cache/cord-316814-9fv9xrln.txt ./txt/cord-316814-9fv9xrln.txt
