Analysis of the contribution of various parameters to the genetic diversity of cherry leaf roll virus

Parametera	Subpopulations defined by host speciesb	Subpopulations defined by country of originb	Subpopulations defined by phylogenetic groupb
Mean entire diversity	0.089 ± 0.010	0.087 ± 0.009	0.085 ± 0.009
Mean intrasubpopulation diversity	0.044 ± 0.004	0.087 ± 0.009	0.022 ± 0.002
Mean intersubpopulation diversity	0.045 ± 0.006	0.003 ± 0.003	0.064 ± 0.008
Nei's Gst coefficient of differentiation	0.507 ± 0.029	0.037 ± 0.032	0.746 ± 0.021

^aGenetic distance and standard error. Standard error computation was done by bootstrap analysis with 1,000 replications.

^bFor calculation of mean entire diversity, mean intrasubpopulation diversity, intersubpopulation diversity, and Nei's coefficient of differentiation, only sequences from groups with more than three members were included in the analysis (for subpopulations defined by host, country of origin, and phylogenetic group 35, 51, and 56 sequences, respectively).
