The Prokaryotic Code: Introduction

The nomenclature of prokaryotes is regulated by the International Code of Nomenclature of Prokaryotes (The Prokaryotic Code) (1 ), which codifies the rules and recommendations governing how the names of prokaryotes are to be proposed and accepted. The Prokaryotic Code outlines the requirements for valid publication of new names of prokaryotes in the International Journal of Systematic and Evolutionary Microbiology (IJSEM) for priority, legitimacy and standing in nomenclature.

On January 05, 2020, the Chair of the International Committee on Systematics of Prokaryotes (ICSP) proposed rules to be adopted to emend The International Code of Prokaryotes (The Code), regarding the nature of nomenclatural type material acceptable under the Rules of The Code.

In keeping with Article 4 of the ICSP Statutes, the Editorial Board of the International Code of Nomenclature of Prokaryotes (ICNP) is conducting an open electronic meeting concerning proposals for changes in The Code.

The first phase of the meeting will take place from January 05, 2020, until March 01, 2020. It is intended to allow open discussion of the proposals as an e-mail chain among the members of the ICSP and other interested parties. Comments may be made by the ‘reply-all’ option on your email server. The second phase of the meeting will take place from March 01 to March 31, 2020 and will consist of voting on the proposed rules changes. Only members of the ICSP may vote.

20200229: The open discussion phase will continue until March 31, 2020.

The Comments and Responses of the open discussion are compiled as a pdf file for review.
