FIG 6.

Taxonomic hierarchy for the proposed B. cereus group nomenclature. Taxonomic levels are listed in the left margin, with levels which are optional/not applicable to all organisms denoted as such. Rounded boxes shaded in light green correspond to possible taxonomic designations at their respective level, while blue boxes correspond to requirements that an isolate and/or its genome must meet to be assigned that designation. Possible forms which the final taxonomic assignment can take can be found in the gray box at the bottom of the chart.
