    Notes:
    • ⊕ Emendation accompanied by the proposal of 5 new species in the genus.

• Notes:
  • 🙄 This taxon name is occasionally misprinted (or affected by an OCR error) in some sources as: "Pseudohizobium".
  • 🧔 This taxon was discussed in a meeting of a Taxonomic Subcommittee of the ICSP. Publication: de Lajudie P, Young JPW. International Committee on Systematics of Prokaryotes Subcommittee on the Taxonomy of Rhizobia and Agrobacteria Minutes of the closed meeting by videoconference, 17 July 2019. Int J Syst Evol Microbiol 2020; 70:3563-3571.
  • 🧔 This taxon was discussed in a meeting of a Taxonomic Subcommittee of the ICSP. Publication: Mousavi SA, Young JPW. International Committee on Systematics of Prokaryotes Subcommittee on the Taxonomy of Rhizobia and Agrobacteria. Minutes of the closed annual meeting: videoconference on 11 October 2022 followed by online discussion until 31 December 2022. Int J Syst Evol Microbiol 2023; 73:5856.
  • 😢 The terminology used by the authors is in line with many other taxonomic studies and does not negatively affect their main results; some improvements may nevertheless be possible. Contrasting the term "chemotaxonomic" with "phenotypic" is not recommended. Using the term "phylogenetic data" (or equivalent) for sequence data is not advocated. See the LPSN phylogeny page for details. Publication: Göker M. What can genome analysis offer for bacteria? In: Bridge P, Smith D, Stackebrandt E (eds), Trends in the systematics of bacteria and fungi, CAB International, Wallingford, 2021, p. 255-281.
  • 🎰 The BRCs most frequently used for deposits in this group are: DSM: 4; JCM: 2; CFBP: 1; NRRL: 1; MCCC: 1; CCUG: 1; CECT: 1; KCTC: 1.
