Dolichospermum Flos-aquae

	Dolichospermum Flos-aquae ''Dolichospermum flos-aquae'' is a species of cyanobacteria belonging to the family Aphanizomenonaceae. Type locality: Sweden, Denmark, Scotland, France, Germany, USA. Taxonomy It was originally described as ''Anabaena flos-aquae''. ''Dolichospermum'' was created in 2009, bringing in a well-defined group from ''Anabaena''. The similarly-named ''Aphanizomenon flos-aquae'' falls into the clade, but was not renamed. Genomes As of 2025, 4 genomes of ''D. flos-aquae'' are available on NCBI. As of 2025 (Release 10-RS226), GTDB's genome-based taxonomy assigns the genomes sequenced as ''D. flos-aquae'' as: * ''Dolichospermum flos-aquae'' LEGE 04289, assigned to ''Dolichospermum planctonicum'' * ''Dolichospermum flos-aquae'' CCAP 1403/13F, assigned to ''Dolichospermum lemmermannii'' as species-representative * ''Dolichospermum flos-aquae'' UHCC 0037, assigned to ''Dolichospermum heterosporum ''Dolichospermum'' is a genus of cyanobacteria belonging to the family Nostocaceae.

picture info	Cyanobacteria Cyanobacteria ( ) are a group of autotrophic gram-negative bacteria that can obtain biological energy via oxygenic photosynthesis. The name "cyanobacteria" () refers to their bluish green (cyan) color, which forms the basis of cyanobacteria's informal common name, blue-green algae. Cyanobacteria are probably the most numerous taxon to have ever existed on Earth and the first organisms known to have produced oxygen, having appeared in the middle Archean eon and apparently originated in a freshwater or terrestrial environment. Their photopigments can absorb the red- and blue-spectrum frequencies of sunlight (thus reflecting a greenish color) to split water molecules into hydrogen ions and oxygen. The hydrogen ions are used to react with carbon dioxide to produce complex organic compounds such as carbohydrates (a process known as carbon fixation), and the oxygen is released as a byproduct. By continuously producing and releasing oxygen over billions of years, cyanobacte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

	GTDB The Genome Taxonomy Database (GTDB) is an online database that maintains information on a proposed nomenclature of prokaryotes, following a phylogenomic approach based on a set of conserved single-copy proteins. In addition to resolving paraphyletic groups, this method also reassigns taxonomic ranks algorithmically, updating names in both cases. Information for archaea was added in 2020, along with a species classification based on average nucleotide identity. Each update incorporates new genomes as well as automated and manual curation of the taxonomy. An open-source tool called GTDB-Tk is available to classify draft genomes into the GTDB hierarchy. The GTDB system, via GTDB-Tk, has been used to catalogue not-yet-named bacteria in the human gut microbiome and other metagenomic sources. The GTDB is incorporated into the ''Bergey's Manual of Systematics of Archaea and Bacteria'' in 2019 as its phylogenomic resource. Methodology The genomes used to construct the phylogeny ar ...

	Dolichospermum Planctonicum ''Dolichospermum'' is a genus of cyanobacteria belonging to the family Nostocaceae. It was created by splitting from ''Anabaena'' using molecular evidence. It is paraphyletic as the author intends: the genera ''Aphanizomenon'' and ''Cuspidothrix'', though cladistically included, have "distinct and unique" morphological features that set them apart. The genus has cosmopolitan distribution. Many of the morphospecies in ''Anabaena'', ''Dolichospermum'', and ''Aphanizomenon'' (ADA clade) are not monophyletic. Work is underway to sequence more genomes from these genera to produce a species classification based on genetic branching. Species As accepted by the GBIF: ''Dolichospermum affine'' ''Dolichospermum berezowskii'' ''Dolichospermum circinale'' ''Dolichospermum compactum'' ''Dolichospermum crassum'' ''Dolichospermum curvum'' ''Dolichospermum danicum'' ''Dolichospermum delicatulum'' ''Dolichospermum ellipsoides'' ''Dolichospermum farciminiforme'' ''Dolichosper ...
