The genome sequence of Bacillus subtilis subsp. spizizenii W23: insights into speciation within the B. subtilis complex and into the history of B. subtilis genetics.
Abstract
The genome sequence of Bacillus subtilis subsp. spizizenii W23 has been determined. The sequence strongly suggests that W23 is a direct descendant of B. subtilis ATCC 6633. W23 shares a 3.6 Mb core genome with the intensively studied model organism B. subtilis subsp. subtilis 168, and gene order within this core has been strongly conserved. Additionally, the W23 genome has 157 accessory (that is, non-core) genome segments that are not found in 168, while the 168 genome has 141 segments not found in W23. The distribution of sequences similar to these accessory segments among other genomes of the B. subtilis species complex shows that those sequences having entered into the phylogeny of the complex more recently tend to be larger and more AT-rich than those having entered earlier. A simple model can account for these observations, in which parasitic or symbiotic DNAs are transferred into the genome and then are reduced in size and modified in base composition during speciation.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
