Xylella fastidiosa, a fastidious bacterium causing disease in over 100 plant species, is classified as a single species, although genetic studies support multiple taxons. To determine the taxonomic relatedness among strains of X. fastidiosa, we conducted DNA-DNA relatedness assays and sequenced the 16S–23S intergenic spacer (ITS) region using 26 strains from 10 hosts. Under stringent conditions...

In a series of articles, Rieppel (2005, Biol. Philos. 20:465-487; 2006a, Cladistics 22:186-197; 2006b, Systematist 26:5-9), Keller et al. (2003, Bot. Rev. 69:93-110), and Nixon and Carpenter (2000, Cladistics 16:298-318) criticize the philosophical foundations of the PhyloCode. They argue that species and higher taxa are not individuals, and they reject the view that taxon names are rigid desig...

Here, we present the complete genome sequence of Thermodesulfobacterium commune DSM 2178(T) of the phylum Thermodesulfobacteria.

Bacteria belonging to the phylum Gemmatimonadetes are found in a wide variety of environments and are particularly abundant in soils. Here, we present the complete genome sequence and methylation pattern of the newly described Gemmatirosa kalamazoonensis type strain.
