    • ⊕ Emendation accompanied by the proposal of 3 new species in the genus.
    • 🧍 According to the Judicial Commission [2], further taxonomic studies have shown that there is reason to consider the names Sinorhizobium Chen et al. 1988 and Ensifer Casida 1982 to be synonyms, and the Rules of the Bacteriological Code indicate that the principle of priority would result in the members of the genus Sinorhizobium being transferred to the genus Ensifer, as proposed by J.M. Young 2003 [1].

• Notes:
  • 🚂 For the type species of this genus another name is in use, which is affiliated with the genus Ensifer Casida 1982. Publication: Young JM. The genus name Ensifer Casida 1982 takes priority over Sinorhizobium Chen et al. 1988, and Sinorhizobium morelense Wang et al. 2002 is a later synonym of Ensifer adhaerens Casida 1982.

  • 💁 Taxonomists who have recently focused on this group are the corresponding authors of Rincon-Rosales et al. (2009), Yan et al. (2016). Editors in search of reviewers are advised to consider additional criteria such as whether a taxon is covered by one of the ICSP subcommittees.
  • ❗ Sinorhizobium 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).
