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.
