Isolation and characterization of a novel Lambda-like phage infecting the bloom-forming cyanobacteria Cylindrospermopsis raciborskii.

ABSTRACT: Cylindrospermopsis raciborskii is a central bloom-forming cyanobacteria. However, despite its ecological significance, little is known of its interactions with the phages that infect it. Currently, only a single sequenced genome of a Cylindrospermopsis-infecting phage is publicly available. Here we describe the isolation and characterization of Cr-LKS3, a second phage infecting Cylindrospermopsis. Cr-LKS3 is a siphovirus with a higher genome similarity to prophages within heterotrophic bacteria genomes than to any other cyanophage/cyano-prophage, suggesting that it represents a novel cyanophage group. The function, order and orientation of the 72 genes in the Cr-LKS3 genome are highly similar to those of Escherichia virus Lambda (hereafter Lambda), despite the very low sequence similarity
