( 2008 ) Taxonomic study of a chromomycin-producing strain and reclassification of Streptomyces cavourensis subsp. washingtonensis as a later synonym of Streptomyces griseus. PMID : 19060058 DOI : 10.1099/ijs.0.65628-0 Abstract >>
A chromomycin-producing actinomycete, strain AP19, was isolated from a sample of faeces collected from Foping national nature reserve in China. Chemotaxonomic and morphological properties indicated that the novel isolate was a member of the genus Streptomyces. Phylogenetic analyses based on an almost complete 16S rRNA gene sequence of the strain and on the 120-nt nucleotide variable gamma-region of this molecule revealed that it was closely related to Streptomyces griseus ISP 5236(T) and Streptomyces cavourensis subsp. washingtonensis ATCC 27732(T). DNA-DNA relatedness values among these strains were above 70 %. Streptomyces cavourensis subsp. washingtonensis could be readily distinguished from Streptomyces cavourensis ATCC 14889(T) by differing BOX-PCR fingerprinting patterns, relatively low 16S rRNA gene sequence similarity and a low DNA-DNA relatedness value. It is proposed, therefore, that Streptomyces cavourensis subsp. washingtonensis is a later synonym of Streptomyces griseus.

( 2012 ) Reassessment of the status of Streptomyces setonii and reclassification of Streptomyces fimicarius as a later synonym of Streptomyces setonii and Streptomyces albovinaceus as a later synonym of Streptomyces globisporus based on combined 16S rRNA/gyrB gene sequence analysis. PMID : 22286909 DOI : 10.1099/ijs.0.040287-0 DOI : 10.1099/ijs.0.040287-0 Abstract >>
The 16S rRNA and gyrB genes of 22 Streptomyces strains belonging to the Streptomyces griseus cluster were sequenced, and their taxonomic positions were re-evaluated. For correct analysis, all of the publicly available sequences of the species were collected and compared with those obtained in this study. Species for which no consensus sequence could be identified were excluded from the phylogenetic analysis. The levels of 16S rRNA gene sequence similarity within the cluster ranged from 98.6 to 100% with a mean value of 99.6 �� 0.3%, and those of the gyrB gene ranged from 93.6 to 99.9% with a mean value of 96.3 �� 1.5%. The observed average nucleotide substitution rate of the gyrB gene was ten times higher than that of the 16S rRNA gene, showing a far higher degree of variation. Strains sharing 99.3% or more gyrB sequence similarity (corresponding to an evolutionary distance of 0.0073) always formed monophyletic groups in both trees. Through the combined analysis of the two genes, clear cases of synonymy could be identified and, according to the priority rule, the assertion of the status of Streptomyces setonii as a distinct species and the reclassification of Streptomyces fimicarius as a later synonym of S. setonii and Streptomyces albovinaceus as a later synonym of Streptomyces globisporus are proposed. Emended descriptions of S. setonii and S. globisporus are provided.

( 2005 ) Classification of Streptomyces griseus (Krainsky 1914) Waksman and Henrici 1948 and related species and the transfer of 'Microstreptospora cinerea' to the genus Streptomyces as Streptomyces yanii sp. nov. PMID : 16014489 DOI : 10.1099/ijs.0.63654-0 Abstract >>
A soil actinomycete, strain 80-133(T), with the non-validly published name 'Microstreptospora cinerea', was the subject of a polyphasic study designed to clarify its taxonomic status. Comparative 16S rRNA gene sequence studies indicated that the organism belonged to the genus Streptomyces, a result in line with previous chemotaxonomic and morphological data. The strain belonged to the Streptomyces griseus clade, but could be distinguished from representatives of species assigned to this taxon by using DNA-DNA relatedness and phenotypic data. In light of these findings, it is proposed that the organism should be recognized as a novel species of the genus Streptomyces. The name proposed for this taxon is Streptomyces yanii sp. nov., with isolate 80-133(T) (=AS 4.1146(T)=JCM 3331(T)) as the type strain. It was also shown that representative strains of Streptomyces argenteolus, Streptomyces caviscabies, S. griseus and Streptomyces setonii belong to the same genomic species and have key phenotypic properties in common. It is proposed that S. caviscabies and S. setonii should be considered as later heterotypic synonyms of S. griseus and that S. argenteolus AS 4.1693(T) should also be assigned to this taxon.

( 2008 ) A multilocus phylogeny of the Streptomyces griseus 16S rRNA gene clade: use of multilocus sequence analysis for streptomycete systematics. PMID : 18175701 DOI : 10.1099/ijs.0.65224-0 DOI : 10.1099/ijs.0.65224-0 Abstract >>
Streptomycetes are a complex group of actinomycetes that produce diverse bioactive metabolites of commercial significance. Systematics can provide a useful framework for identifying species that may produce novel metabolites. However, previously proposed approaches to the systematics of Streptomyces have suffered from either poor interlaboratory comparability or insufficient resolution. In particular, the Streptomyces griseus 16S rRNA gene clade is the most challenging and least defined group within the genus Streptomyces in terms of phylogeny. Here we report the results of a multilocus sequence analysis scheme developed to address the phylogeny of this clade. Sequence fragments of six housekeeping genes, atpD, gyrB, recA, rpoB, trpB and 16S rRNA, were obtained for 53 reference strains that represent 45 valid species and subspecies. Analysis of each individual locus confirmed the suitability of loci and the congruence of single-gene trees for concatenation. Concatenated trees of three, four, five and all six genes were constructed, and the stability of the topology and discriminatory power of each tree were analysed. It can be concluded from the results that phylogenetic analysis based on multilocus sequences is more accurate and robust for species delineation within Streptomyces. A multilocus phylogeny of six genes proved to be optimal for elucidating the interspecies relationships within the S. griseus 16S rRNA gene clade. Our multilocus sequence analysis scheme provides a valuable tool that can be applied to other Streptomyces clades for refining the systematic framework of this genus.

Streptomyces griseus and related species form the biggest but least well-defined clade in the whole Streptomyces 16S rRNA gene tree. Multilocus sequence analysis (MLSA) has shown promising potential for refining Streptomyces systematics. In this investigation, strains of 18 additional S. griseus clade species were analysed and data from a previous pilot study were integrated in a larger MLSA phylogeny. The results demonstrated that MLSA of five housekeeping genes (atpD, gyrB, recA, rpoB and trpB) is better than the previous six-gene scheme, as it provides equally good resolution and stability and is more cost-effective; MLSA using three or four of the genes also shows good resolution and robustness for differentiating most of the strains and is therefore of value for everyday use. MLSA is more suitable for discriminating strains that show >99 % 16S rRNA gene sequence similarity. DNA-DNA hybridization (DDH) between strains with representative MLSA distances revealed a strong correlation between the data of MLSA and DDH. The 70 % DDH value for current species definition corresponds to a five-gene MLSA distance of 0.007, which could be considered as the species cut-off for the S. griseus clade. It is concluded that the MLSA procedure can be a practical, reliable and robust alternative to DDH for the identification and classification of streptomycetes at the species and intraspecies levels. Based on the data from MLSA and DDH, as well as cultural and morphological characteristics, 18 species and three subspecies of the S. griseus clade are considered to be later heterotypic synonyms of 11 genomic species: Streptomyces griseinus and Streptomyces mediolani as synonyms of Streptomyces albovinaceus; Streptomyces praecox as a synonym of Streptomyces anulatus; Streptomyces olivoviridis as a synonym of Streptomyces atroolivaceus; Streptomyces griseobrunneus as a synonym of Streptomyces bacillaris; Streptomyces cavourensis subsp. washingtonensis as a synonym of Streptomyces cyaneofuscatus; Streptomyces acrimycini, Streptomyces baarnensis, Streptomyces caviscabies and Streptomyces flavofuscus as synonyms of Streptomyces fimicarius; Streptomyces flavogriseus as a synonym of Streptomyces flavovirens; Streptomyces erumpens, 'Streptomyces ornatus' and Streptomyces setonii as synonyms of Streptomyces griseus; Streptomyces graminofaciens as a synonym of Streptomyces halstedii; Streptomyces alboviridis, Streptomyces griseus subsp. alpha, Streptomyces griseus subsp. cretosus and Streptomyces luridiscabiei as synonyms of Streptomyces microflavus; and Streptomyces californicus and Streptomyces floridae as synonyms of Streptomyces puniceus.
