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

“…We discussed the recent paper published by Ma et al [3], who reported an extensive genome-based taxonomic revision of the family Rhizobiaceae with proposals at two levels (species and genus) that will presumably be submitted to the IJSEM for validation. The research and results cover much of the ground of Action Point 8.1 (Minute 8) of our previous meeting [1], which was implemented by P. Young, G.C. diCenzo and N. Kuzmanović.…”

“…The Executive Board of the ICSP (EB-ICSP) asked us, in a letter from the Secretary for Subcommittees, Professor Stephen On, dated 26 September 2023 and Minute 9 of EB-ICSP meeting on 31 August 2023 (www.the-icsp.org/images/minutes/20230928_ EB-ICSP_Meeting-20230831%20-%20Minutes.pdf), to clarify some aspects of Minute 10 of the 2022 Subcommittee meeting [1]. After discussion, the following statements were approved.…”

“…11. 1 The main results of two recent papers [4,5] were presented by P. Young. In these papers, four new species were described to accommodate strains that were previously assigned to the Rhizobium leguminosarum complex.…”

“…Last year (Action Point 13.1 [1]), E. Martinez-Romero agreed to prepare a list of symbiovars, with a small group of Subcommittee members. The list of symbiovars in the genera Bradyrhizobium, Ensifer, Mesorhizobium and Rhizobium was prepared by E. Martinez-Romero and A. Peix, and uploaded in our Subcommittee blog (https://sites.google.com/view/taxonomyagrorhizo/ home/blog).…”
