• Notes:
  • 🚂 For the type species of this genus another name is in use, which is affiliated with the genus Rhizobium Frank 1889 (Approved Lists 1980). Publication: Yoon JH, Kang SJ, Yi HS, Oh TK, Ryu CM. Rhizobium soli sp. nov., isolated from soil. Int J Syst Evol Microbiol 2010; 60:1387-1393. 🇰🇷
  • ❗ Velazquezella is the correct name instead if this genus is regarded as a separate genus (i.e., if its nomenclatural type is not assigned to another genus whose name is validly published, legitimate and not rejected and has priority).
  • 🎰 The BRCs most frequently used for deposits in this group are: JCM: 1; KCTC: 1.
