Recruitment plot of Lactococcus phage 1706 for 6 human gut datasets. Only the 6 viromes with more than 200 reads recruited by this genome were included, i.e. reads having their best BLAST hit with this genome. Stacked histograms represent the total number of reads similar to each 500-nt long genome part, with a different color for each virome. Each gene is plotted as a rectangle on the genome map of the Lactococcus phage 1706 at the bottom, with hypothetical proteins in blue, and characterized genes in red. A black frame highlights the three genes involved in host specificity.
