Abstract
Cylindrospermopsis raciborskii is a freshwater cyanobacterium producing bloom events and toxicity in drinking water source reservoirs. We present the first genome sequence for C. raciborskii CS505 (Australia), containing one 4.1-Mbp chromosome and one 110-Kbp plasmid having G+C contents of 40.3% (3933 genes) and 39.3% (111 genes), respectively.
Highlights
Cylindrospermopsis raciborskii is a freshwater cyanobacterium producing bloom events and toxicity in drinking water source reservoirs
In 2010, the draft genome of this strain was analyzed by a combination of 454 and Sanger sequencing, yielding 95 scaffolds with a total length of 3,879,017 bp (4)
The cluster associated with the synthesis of CYL toxin was identified, as it had been previously described (5)
Summary
Cylindrospermopsis raciborskii is a freshwater cyanobacterium producing bloom events and toxicity in drinking water source reservoirs. Cylindrospermopsis raciborskii is defined as a planktonic nitrogen-fixing freshwater cyanobacterium (1). Strain CS505 (CSIRO culture collection) was isolated from Solomon Dam, North Queensland, Australia (2) and characterized based on its production of the hepatotoxin cylindrospermopsin (CYL), a potent protein synthesis inhibitor (3).
