  • a Includes all alleles assigned to cluster I or II. The allele recP116 from GGS strain 4236 formed a third cluster (not assigned to either cluster I or II) and is excluded from this analysis. Cluster II alleles of xpt form two distinct groups (cluster IIa and IIb); the maximal divergence between clusters I and IIa is 3.0%, and that between clusters I and IIb is 3.7%.
