Fig. 3From: Fidelity varies in the symbiosis between a gutless marine worm and its microbial consortiumComparative phylogenetic analyses of O. algarvensis and its microbial consortium members revealed variable patterns of congruence across the six symbionts. Phylogenetic trees based on SNPs across genomes of a host mitochondria (166 SNPs, n = 80), b Ca. Thiosymbion (2872 SNPs, n = 80), c Gamma3 symbiont (618 SNPs, n = 80), d Delta1a symbiont (375 SNPs, n =37), e Delta1b symbiont (624 SNPs, n = 46), f Delta4 symbiont (675 SNPs, n = 67) and g spirochete symbiont (88 SNPs, n = 41). Phylogenies were inferred from genetic distances calculated from posterior genotype probabilities. Scale bars indicate 0.1 substitution per SNP site. Bootstrap support values > 95% are shown in black circles. Support for branches internal to each coloured leaf was omitted for visibilityBack to article page
