Calicivirus RNA recombination 2004-09-14 .txt text/plain 3335 168 45 With the description of statistically significant phylogenetic clades within CV genera, data were available to recognize strains that might be natural recombinants within CVs. Two examples are the well-characterized Argentine strain 320 (Arg320) and Snow Mountain virus (SMV), one of the prototype CVs, recognized to be recombinants when the RNA polymerase and capsid regions of these strains were characterized (Hardy et al., 1997; Jiang et al., 1999) (Fig. 2) . While SMV was likely also to be a recombinant virus, the capsid and RNA polymerase region amplicons of SMV were generated separately and that fact did not exclude the possibility of different sources of strains. Infection of single cells simultaneously by two CVs implies absence of immune or molecular and of 40 nt near the 5' end of that strain's capsid gene (ID="B" sequence for this Fig.) . The sequence data indicated that recombination in strain Arg320 occurred at the ORF1/capsid gene junction where high sequence identity exists between the putative parent clades. ./cache/cord-010161-bcuec2fz.txt ./txt/cord-010161-bcuec2fz.txt
