“…Support for the involvement of B RNA in determining the host range of comoviruses is provided by Evans (1985) who isolated a nitrous acid-induced mutant of CPMV that was unable to infect cowpea plants, and showed that the mutation was located on the B RNA. There are two possible explanations for the apparent inability of strains or pseudo-recombinants containing B RNA from strain O to infect C. quinoa: either B RNA from strain O is incapable of replicating in C. quinoa cells, or virus containing B RNA from strain O, although capable of replicating in the inoculated cell (i.e.…”

cDNA clones specific for the two genomic RNAs of strain O of the comovirus red clover mottle virus (RCMV) were constructed. Using these clones, in conjunction with clones specific for RNAs of RCMV strain S, local lesion isolates containing reciprocal pseudo-recombinants between strains S and O were identified. Investigation of the biological properties of these pseudo-recombinants showed that the ability of RCMV to infect Chenopodium quinoa is determined by B RNA. The results also suggest that both RNAs are involved in symptom formation in Pisum sativum.

SummaryCowpea mosaic virus (CPMV) is the type member of the comovirus group, which contains 14 different plant viruses that have the same structural organization of genomic RNAs and virions and use the same mechanism for expression of the viral RNAs. The combined structure and organization of the two CPMV genomic RNAs is strikingly similar to that of the single genome of animal picornaviruses. This suggests a common ancestry and similar replication mechanisms. CPMV is by far the best-studied comovirus and we shall limit this review to some recent data on this virus. For additional general information the reader is referred to other recent reviews on CPMV and comoviruses."
