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

ABSTRACT We announce here the draft genome sequence of Nostoc piscinale CENA21, a diazotrophic heterocyst-forming cyanobacterium isolated from the Solimoes 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.
