Three alternative proposals to emend the Rules of the International Code of Nomenclature of Prokaryotes to resolve the status of the Cyanobacteria in the prokaryotic nomenclature.

Three alternative proposals to emend the Rules of the International Code of Nomenclature of Prokaryotes are presented to resolve the status of the Cyanobacteria in the prokaryotic nomenclature. Two were earlier published (Oren and Garrity, Int J Syst Evol Microbiol 2014;64 : 309-310; Pinevich, Int J Syst Evol Microbiol 2015;65 : 1070-1074). The third proposal is based on reciprocation of Article 45.1 of the International Code of Nomenclature for algae, fungi, and plants. According to Article 13b of the Statutes of the International Committee on Systematics of Prokaryotes, a decision on these proposals must be reached within 11 months from the date of this publication.
