N.L. gen. n. stanieri, named to honour Roger Y. Stanier, who pioneered the study of cyanobacteria in axenic cultures
Nomenclatural type
Strain: PCC 7202 = ATCC 29140

Taxonomy

Description
Oren et al., 2022:
Cells solitary or in pairs, rarely aggregated within very fine, formless mucilage, cylindrical or subcylindrical, blue-green, more or less with homogeneous content, cell width 1.7–3 µm, cell length 2.6–5.2 µm (up to 12 µm in cells with delayed divisions), dividing transversely, symmetrically or asymmetrically. The cells contain thylakoids arranged densely and more or less in parallel over the whole cell protoplast. Non-motile euryhaline photoautotroph, not capable of facultative photoheterotrophic growth, nitrogenase activity not observed even under anaerobic conditions, insensitive to cyanophage ASM-1, C-phycoerythrin and phycoerythrocyanin not synthesized.

The genome of strain PCC 7202 consists of a chromosome of 3163381 bp with G+C content of 38.7 mol%, encoding 2837 proteins, 43 tRNAs, with three of each 5S, 16S and 23S rRNA genes, and three non-coding RNAs.

Holotype: Exsiccatum no. A-127–1, derived from the axenic strain PCC 7202; stored in the herbarium CBFS at the University of South Bohemia

Reference strain: the genus is represented by the euryhaline strain C. stanieri PCC 7202 (also deposited as strain ATCC 29140), isolated in 1963 by M. Lefèvre from an alkaline pond in Chad (genome: GCA_000317655.1; CP003940.1); 16S rRNA gene sequence accession number: AF132782.
Notes
Oren et al., 2022: The descriptions of Cyanobacterium gen. nov. and C. stanieri sp. nov. are hereby ascribed to the authors R. Rippka and G. Cohen-Bazire who first provided a detailed description of this taxon (Rippka, Cohen-Bazire, 1983). An emended description taking into account later studies is provided in this article, approved by one of the original authors (R. Rippka, co-author of this study). According to previously published phylogenetic inference based on sequence analyses of the 16S rRNA genes, the genus Cyanobacterium can be assigned to the family Geminocystaceae Tuji et al. 2021, validly published under the ICN, and not to the Cyanobacteriaceae Komárek et al. 2014, which at the time was based on the invalid genus name Cyanobacterium, and thus has no nomenclatural standing under the ICN.
