Recovery of structurally intact and infectious poliovirus type 1 from HeLa cells during receptor-mediated endocytosis.

abstract：:Transient expression studies using a Nicotiana benthamiana suspension cell-derived protoplast system have identified a minimal sequence that is necessary and sufficient for activation of the tomato golden mosaic virus coat protein (CP) promoter by the viral TrAP protein (also called AL2). The sequence has a bipartite ...
