Amplification for Whole Genome Sequencing of Bacteriophages from Single Isolated Plaques Using SISPA.

Genomics has greatly transformed our understanding of phage biology; however, traditional methods of DNA isolation for whole genome sequencing have required phages to be grown to high titers in large-scale preparations, potentially selecting for only those phages that can grow efficiently under laboratory conditions. This may also select for mutations or deletions that enable more efficient growth in culture. The ability to sequence a bacteriophage genome from a single isolated plaque reduces these risks while decreasing the time and complexity of bacteriophage genome sequencing. A method of amplification and library preparation is described, utilizing Sequence Independent Single Primer Amplification (SISPA), that can be used for whole genome shotgun sequencing of bacteriophages from a single isolated plaque.
