Abstract
When the full-length coat protein (CP) of the potyvirus, Johnsongrass mosaic virus (JGMV), was expressed in Escherichia coli or yeast, it assembled to form potyvirus-like particles. The particles were heterogeneous in length with a stacked-ring appearance and resembled JGMV particles in their flexuous morphology and width. This cell-free assembly system should permit analysis of the mechanisms of particle assembly and genome encapsidation. Two mutant forms of CP produced by site-directed mutagenesis failed to assemble into virus-like particles.
