Complete genome sequence of a cylindrospermopsin-producing cyanobacterium, Cylindrospermopsis raciborskii CS505, containing a circular chromosome and a single extrachromosomal element

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.
