-values for type I-C, PAM GAA, and genus Streptococcus . Main plot: Each line shows one phage genome and is colored according to host species (Additional file 1: Figure S1). Median of rPAM for CRISPR + is given as a red line and for CRISPR - as a green line. Inserted plot: Distributions of rPAM for CRISPR + (gray) and CRISPR - (white). Strains are ordered by rPAM of the resampling method (bottom to top): 315.5, phiNJ2, 315.4, 315.1, phi3396, 315.2, 315.3, P9, 315.6, LYGO9, JX01, MM1, MM1_1998, M102AD, YMC-2011, 2167, Abc2, M102, Sfi21, 34117, PH15, DT1, Cp-1, O1205, 2972, V22, 8140, Sfi11, SMP, ALQ13.2, TP-J34, Sfi19, 7201, 858, 5093, SM1, EJ-1, PH10, 11865, phi-SsUD.1, 23782, phi-m46.1, 040922, Dp-1.
