Abstract

We have determined the draft genome sequences of Thiorhodococcus mannitoliphagus and Thiorhodococcus minor for comparison with those of T. drewsii and Imhoffiella purpurea According to average nucleotide identity (ANI) and whole-genome phylogenetic comparisons, these two species are clearly distinct from the Imhoffiella species and T. drewsii.

Highlights

  • We have determined the draft genome sequences of Thiorhodococcus mannitoliphagus and Thiorhodococcus minor for comparison with those of T. drewsii and Imhoffiella purpurea

  • Whole-genome-based phylogenetic analysis of all of the Thiorhodococcus genomes using RAxML within PATRIC [13, 14] showed two distinct groups, with T. minor and T. mannitoliphagus as the closest relatives and the group of T. drewsii and I. purpurea more distantly related, consistent with the average nucleotide identity (ANI) analysis (Fig. 1). These whole-genome analyses suggest that while T. minor and T. mannitoliphagus group together, T. drewsii could be included in the genus Imhoffiella if further sequence, morphological, and physiological studies warrant it, our studies suggest that all four should remain in the genus Thiorhodococcus, which is clearly differentiated from Allochromatium

  • These whole-genome shotgun projects have been deposited at DDBJ/ENA/GenBank under the accession numbers JAAIJQ000000000 for Thiorhodococcus minor and JAAIJR000000000 for Thiorhodococcus mannitoliphagus

Summary

Introduction

We have determined the draft genome sequences of Thiorhodococcus mannitoliphagus and Thiorhodococcus minor for comparison with those of T. drewsii and Imhoffiella purpurea. A JSpecies comparison [12] of average percent nucleotide identity (ANIb) showed 82.3% identity between T. minor and T. mannitoliphagus. Both genomes gave an ANI of 75% with Thiorhodococcus drewsii DSM15006 and 75 to 76% with Imhoffiella purpurea
