WebbThe primary objec- tive was to devise a classification that would reflect the phylogeny of prokaryotes, as defined by 16S rDNA se- quence analysis, while simultaneously placing all of the validly named members of a given taxon into the clas- sification at a single point, based on the sequence of the type strain, type species, or type genus. 1 Under ideal …
