GTDB R232 places this taxon's 80 genomes in 3 species.

Split up: GTDB gives this taxon more names in a later release, across R207, R214, R220, R226, R232.

SILVA

Release

Release

id: Providencia_D_731637 alcalifaciens · Greengenes2 2024.09

Genome accession. Linked via GTDB R220 genome accessions — the same physical genomes, not a name match.

d__Bacteria; p__Pseudomonadota; c__Gammaproteobacteria; o__Enterobacterales_737866; f__Enterobacteriaceae_A_732334; g__Moellerella; s__Providencia_D_731637 alcalifaciens

Only 2 genomes — below the threshold for detecting a split, so “current” here means unverified, not confirmed.

eHOMD

Release 4.2

No record in eHOMD 4.2.

Each panel shows one release. Switch a release to see how that database's answer changes — the taxon is held fixed by NCBI taxid, so every panel describes the same organism. Each panel also says how it was linked; how the databases are joined explains the routes.

Each column is the release its box shows. marks the first rank at which a database's name differs from NCBI's, by exact text; a suffix such as _A counts. SILVA's path and eHOMD's columns end at genus, so their species row is blank; the box above names the species. Levels a source labels outside these seven ranks are in the API's ranks and not drawn here.
