A Circularized genome map of vB_OliS_GJ44. The outer circle represents genes. Putative functional categories were defined according to annotation and are represented by different colors. The second circle shows the length of the genome, the green arc represents the length of the tail-related genes, and the third circle is a tetranucleotides correlation. The weaker correlations are circled by a red ellipse. B Cumulative GC skew analysis of the phage genome sequence. The global minimum and maximum are displayed in the cumulative graph were calculated by using a window size of 1,00 bp and a step size of 100 bp. The GC-skew and the cumulative GC-skew are represented by blue and red lines, respectively. The minimum and maximum of a GC-skew can be used to predict the origin of replication (500 nt) and the terminus location (33,500 nt)
