Members of the genus Cylindrospermopsis represent an important environmental and health concern. Strains CS-508 and MVCC14 of C. raciborskii were isolated from freshwater reservoirs located in Australia and Uruguay, respectively. While CS-508 has been reported as non-toxic, MVCC14 is a saxitoxin (STX) producer. We annotated the draft genomes of these C. raciborskii strains using the assembly of reads obtained from Illumina MiSeq sequencing. The final assemblies resulted in genome sizes close to 3.6 Mbp for both strains and included 3202 ORFs for CS-508 (in 163 contigs) and 3560 ORFs for MVCC14 (in 99 contigs). Finally, both the average nucleotide identity (ANI) and the similarity of gene content indicate that these two genomes should be considered as strains of the C. raciborskii species.

从澳大利亚和乌拉圭的淡水开花事件中分离出的拟南芥（Cylindrospermopsis raciborskii）菌株CS-508和MVCC14的基因组序列草案

圆柱精子属的成员代表着重要的环境和健康问题。从位于澳大利亚和乌拉圭的淡水水库中分别分离了拉美梭菌的CS-508和MVCC14菌株。虽然据报道CS-508是无毒的，但MVCC14却是毒素（STX）的生产商。我们使用从Illumina MiSeq测序获得的读段的集合注释了这些拉美梭菌菌株的基因组草图。最终的组装导致两个菌株的基因组大小均接近3.6 Mbp，并且包括CS-508的3202个ORF（163个重叠群）和MVCC14的3560个ORF（99个重叠群）。最后，平均核苷酸同一性（ANI）和基因含量的相似性都表明这两个基因组应被视为拉美梭菌的菌株。
