Abstract
Based on the 16S rRNA gene sequences similarity of > 99.8%, the phylogeny of 88 Paraburkholderia strains was reconstructed. Further, they were subjected to overall genome-related indices (OGRI), which resulted in the identification of distinct pairs of species that were closely related. A pair consist of the type strains of Paraburkholderia insulsa and Paraburkholderia fungorum possessed a dDDH value of 87.9%, correspondingly, and the average nucleotide identity (ANI) value was 98.5%. Based on the phylogenetic analysis, OGRI and phenotypical evidence, P. insulsa was proposed as a later heterotypic synonym of P. fungorum. Furthermore, a pair comprising type strains of Paraburkholderia terrae and Paraburkholderia steynii possessed dDDH and ANI values of 71.2% and 96.6%, respectively, and difference in phenotypic traits, which supports a subspecies proposal within these taxa. Thus, the recently described Paraburkholderia steynii was proposed into two subspecies namely Paraburkholderia terrae subsp terrae subsp. nov and as Paraburkholderia terrae subsp. steynii subsp. nov.
