Abstract
Molecular taxonomy of plant viruses is now nearing completion (Mayo and Pringle, 1998; Pringle, 1998) primarily because of the evolutionary relationships that emerged from comparative studies on nucleotide and protein sequences and RNA-dependent RNA polymerase gene of various plant viruses (Koonin, 1991; Koonin and Dolja 1993; Zanotto et al., 1996). Four distinct supergroups of plus-sense RNA plant viruses are now recognized. Based on similarity of the basic genome features between different groups of animal and plant viruses, two distinct supergroups of plus-RNA plant viruses initially delimited were plant “picorna-like” and plant “alpha-like” supergroups. The two more supergroups of plus-RNA plant viruses recognized recently are the `sobemo-like“ and ”carmo-like“ supergroups.
