Comparative analysis of S. marcescens isolates. Clinical, non-clinical and collection isolates are represented in yellow, pink and green, respectively. a Flowerplot representing the pan-genome of 35 S. marcescens isolates. Labels on petal tips represent strain-specific genes. Numbers within colored petal areas represent strain-specific genes. b Multi-locus maximum likelihood tree reconstructed using concatenated alignment of ten single-copy core genes. Branch labels represent bootstrap support (in percentage; 1000 bootstrap replicates). The blue-to-red heatmap accounts for the distance of each isolate to S. marcescens UENF-22GI, estimated by the digital DNA:DNA hybridization (dDDH) method (d0 formula)
