Fig. 2. — Phylogenetic and population genetic analysis of East Asia H. pylori strains. (a) Phylogenetic tree of East Asia genomes combined with reference sequences from global H. pylori populations. Diamonds indicate Japanese and Korean isolates that are dispersed in other subgroups. (b) Co-ancestry matrix of East Asia isolates calculated using fineSTRUCTURE after removing isolates with highly clonal relatedness. The tree inferred on the left of the co-ancestry matrix indicates the relationships between groups with distinct ancestry profile as inferred by fineSTRUCTURE. On the right side, the first column shows the geographic origin of each isolate. The second column indicates each subgroup with a distinct colour.
