Abstract
Sinorhiozbium bacteriophage HMSP1-Susan has a genome of 51,963 bp in size, with a GC content of 52.5%. It contains 97 putative coding sequences; 83% of these coding sequences (CDS) encode proteins classified as hypothetical or having unknown functions. HMSP1 has limited homology to previously reported viruses and likely represents a new phage that infects this nitrogen-fixing bacterium.
