Abstract
Three freshwater planktonic filamentous cyanobacterial strains, Dolichospermum planctonicum NIES-80, Planktothrix agardhii NIES-905, and Sphaerospermopsis reniformis NIES-1949, were sequenced. The genome sizes of NIES-80, NIES-905, and NIES-1949 were 4,571,002 bp, 5,512,454 bp, and 6,025,023 bp, and the number of protein-coding genes in each genome was 4,009, 4,925, and 5,408, respectively.
Highlights
Water blooms, called “cyanobacterial blooms” (1), are mainly formed by some planktonic cyanobacterial species in mesotrophic-eutrophic freshwater (2)
Some strains of Planktothrix agardhii produce a cyanotoxin, microcystin, that is synthesized by the mcy gene cluster (11)
The draft genome sequences of Dolichospermum planctonicum National Institute for Environmental Studies (NIES)-80, Planktothrix agardhii NIES-905 (ϭ CCAP 1459/11A), and Sphaerospermopsis reniformis NIES-1949 have been deposited in DDBJ/EMBL/GenBank under the accession numbers BJCF01000001 to BJCF01000201, BJCD01000001 to BJCD01000193, and BJCE01000001 to BJCE01000680, respectively
Summary
Called “cyanobacterial blooms” (1), are mainly formed by some planktonic cyanobacterial species in mesotrophic-eutrophic freshwater (2). The draft genome sizes of NIES-80, NIES-905, and NIES-1949 were 4,571,002 bp (GC content, 37.7%), 5,512,454 bp (GC content, 39.5%), and 6,025,023 bp (GC content, 37.5%), respectively (Table 1). The genome completeness rates were 99.22% (NIES-80), 100.00% (NIES-905), and 98.89% (NIES-1949), respectively, as evaluated by CheckM analysis (10).
