International Code of Nomenclature of Prokaryotes. Prokaryotic Code (2022 Revision)

• Fourteen years have passed since the International Committee on Systematics of Prokaryotes (ICSP) at its plenary meeting in Istanbul in 2008 approved the previous version of the International Code of Nomenclature of Prokaryotes (ICNP, the Prokaryotic Code, the Code), and we thank the Editors for overseeing its publication in 2019 [1]. Updating the Prokaryotic Code was long overdue in view of the large number of subsequent proposals to emend the General Considerations, Principles, Rules and Recom-mendations, and Appendices of the Code. In the period 2008-2020, 45 such proposals were published in the International Journal of Systematic and Evolutionary Microbiology [2]. Most of those were only recently discussed and voted on by the members of the ICSP, following the adoption of revised statutes in 2019 [3], which transferred responsibility for dealing with proposed emendations from the Judicial Commission to the Editorial Board of the ICNP. The current Editorial Board of the ICNP, appointed in 2020, has therefore prepared proposals for emendation of the Code, which were submitted for balloting among the full and co -opted members of the ICSP, in accordance with its statutes [3]. The ballot took place in April-June 2022 and we present here the 2022 revision of the Code, incorporating the changes approved by the voting members of the ICSP. To comply with Article 4(d) of the statutes of the ICSP that state that the business of the ICSP should be conducted publicly, the voting was preceded by a 6 -month period (July-December 2021), during which anyone interested could post comments via an online platform [4]. The editorial board of the ICSP is pleased with the lively discussions that developed on many issues relating to the Code. Numerous suggestions and ideas to improve the text of the Code were brought forward during this public discussion and many are incorporated in the current revision. Two previously approved major changes are also included in the new revision: (1) The rank of phylum was added to the ranks covered by the rules of the Code. This important change was approved by the ICSP in a separate ballot held in 2021 after a public discussion was held on this topic [5]. (2) The formal inclusion of the Cyanobacteria in the rules of the Code [6], a change that required modification of numerous rules to harmonize the treatment of the nomenclature of the Cyanobacteria with the relevant rules of the International Code of Nomenclature for algae, fungi, and plants [7]. This change was also approved by the ICSP in a separate ballot held in 2021, following a public discussion. Numerous minor modifications of the Code have been made that clarify its meaning, affecting topics such as notes, nomenclatural types, and effective publications, as well as valid publication, legitimacy, priority and orthography of names. The Judicial Commission of the ICSP issued numerous opinions in the past few years, and Appendix 5 - Opinions Relating to the Nomenclature of Prokaryotes - has been updated to include the latest opinions issued. Based on those opinions, Appendix 4 - Conserved and Rejected Names of Prokaryotic Taxa - has been updated, as well. Numerous additions have been made in Appendix 9 - Orthography. The new version of this Appendix should be useful for assisting authors in proposing correctly formed names that comply with the rules of the Code. We aimed to shorten and simplify the ICNP where possible. Therefore, we have not reprinted the prefaces to the earlier versions of the Code and have not included the extended information about the older versions of the different codes of nomenclature (Appendix 1), the recipients of the van Niel International Prize prior to 2014 (Appendix 12) and activities of the congresses prior to 2019 (Appendix 13). These changes were endorsed by the ICSP. The earlier information is available in the 2008 revision of the ICNP [1].
