id: s__Agrobacterium tumefaciens / s__Agrobacterium radiobacter / s__Agrobacterium leguminum · GTDB R232
Database's species id. At its weakest, linked by GTDB's own NCBI species id rather than the genome's raw one.
d__Bacteria;p__Pseudomonadota;c__Alphaproteobacteria;o__Rhizobiales;f__Rhizobiaceae;g__Agrobacterium;s__Agrobacterium tumefaciens
Warning: GTDB R232 places this taxon's 285 genomes in 3 species.
Renamed: GTDB gives this taxon a different name in R207, R214, R220, R226, R232.
SILVA
Agrobacterium radiobacter
id: KY643708 · SILVA 138.2
Walked up to species. At its weakest, linked by walking up 1 level from a strain or subspecies record to the species.
Bacteria;Pseudomonadota;Alphaproteobacteria;Hyphomicrobiales;Rhizobiaceae;Agrobacterium;
Renamed: SILVA gives this taxon a different name in 132, 138, 138.1, 138.2, 144.
Greengenes2
Agrobacterium fabrum
id: Agrobacterium fabrum · Greengenes2 2024.09
Genome accession. Linked via GTDB R220 genome accessions — the same physical genomes, not a name match.
d__Bacteria; p__Pseudomonadota; c__Alphaproteobacteria; o__Rhizobiales_505101; f__Rhizobiaceae; g__Agrobacterium; s__Agrobacterium fabrum
Renamed: Greengenes2 gives this taxon a different name in 2022.10, 2024.09.
eHOMD
Release 4.2Agrobacterium tumefaciens
id: HMT-485 · eHOMD 4.2
Exact taxid. Linked by NCBI taxid — eHOMD records the same id NCBI does.
Bacteria;Pseudomonadota;Alphaproteobacteria;Hyphomicrobiales;Rhizobiaceae;Agrobacterium
Only 1 genome — below the threshold for detecting a split, so “current” here means unverified, not confirmed.
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.
