Genomic taxonomy of Novosphingobium strains. (A) Neighborhood joining consensus tree inferred with 1000 replicates constructed using the concatenated MUSCLE alignment adjusted by Gblocks with conservative. The tree is drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer the phylogenetic tree. The evolutionary distances were computed using the Poisson correction method and are in the units of the number of amino acid substitutions per site. All ambiguous positions were removed for each sequence pair. There were a total of 310,459 positions in the final dataset. Sphingopyxis alaskensis and Erythrobacter litoralis were used as outgroups. (B) AAI and genome dissimilarity (multiplied by 1000) of different Novosphingobium pairs (C) Dinucleotide relative abundance in Novosphingobium strains. Dotted line indicates the normal range of dinucleotide relative abundance.
