Draft Genome Sequence of the N2-Fixing Cyanobacterium Nostoc piscinale CENA21, Isolated from the Brazilian Amazon Floodplain.

We announce here the draft genome sequence ofNostoc piscinaleCENA21, a diazotrophic heterocyst-forming cyanobacterium isolated from the Solimões River, Amazon Basin, Brazil. It consists of one circular chromosome scaffold with 11 contigs and total size of 7,094,556 bp. Secondary metabolite annotations indicate a good source for the discovery of novel natural products.

Draft Genome Sequence of the Picocyanobacterium Synechococcus sp. Strain GFB01, Isolated from a Freshwater Lagoon in the Brazilian Amazon.

We present the draft genome of the cyanobacterium strain Synechococcus sp. GFB01, the first genome sequencing of this genus isolated from South America. This draft genome consists of 125 contigs with a total size of 2,339,812 bp. Automatic annotation identified several genes involved with heavy metal resistance and natural transformation.
