Distribution of Genes Stratified by Genera in Each Conglomerate of the Two-Step Cluster Analysis

	AlphaPVs, % (n = 63)			BetaPVs, % (n = 45)			GammaPVsa, % (n = 45)
	Cluster 1	Cluster 2	Cluster 3	Cluster 1	Cluster 2	Cluster 3	Cluster 1	Cluster 2	Cluster 3
E6	100	—	—	—	100	—	100	—	—

Note.—Table should be read as follows taking AlphaPVs as an example: For AlphaPVs, two-step cluster analysis distinguishes three different clusters. Cluster 1 groups E6, E7, and E4 genes. Cluster 2 groups E1 and E2 genes. Finally, cluster 3 groups L1 and L2 genes.

^aFor E6, n = 42.
