The Buchnera GroEL homologue from the sweetpotato whitefly B. tabaci, was later shown to be able to bind a variety of plant viruses, mediated by their capsid, mostly those whose virion is of globular or geminate shape, and whose CP has a high positive charge, a high percentage of arginine and a high isoelectric point???many of which are vectored by aphids, especially M. persicae [88].
