• Notes:
  • 🚋 The type species of this genus has alternatively been placed in the genus Rhizobium Frank 1889 (Approved Lists 1980). Publication: Bibi F, Chung EJ, Khan A, Jeon CO, Chung YR. Rhizobium halophytocola sp. nov., isolated from the root of a coastal dune plant. Int J Syst Evol Microbiol 2012; 62:1997-2003. 🇰🇷
  • 🧔 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 2 October 2023, followed by online discussion until 31 December 2023. Int J Syst Evol Microbiol 2024; 74:6276. 🇫🇮
  • 😢 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. The phrase "validly described" is misleading. 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. 🇬🇧
