In the second paper of the series, we describe the genome of a siphovirus that infects Halorubrum coriense. It was isolated from Lake Hardy way back in 1998, and the genome shows it is quite distinct from other reported caudoviruses of haloarchaea. The graphical abstract above shows a picture of Hardy Lake in the background, and a map of the Hardycor1 genome in the foreground. We also observed a number of active proviruses occurred in our stocks of this virus and other haloviruses, highlighting the dynamic nature of proviruses in haloarchaea.
