Fig. 4
Summary of infection dependent increases. Different groups of viruses show different timings in their infection dependent rank increases. The tails (indicated by circles) and heads (indicated by triangles) of arrows indicate the two time points in comparisons. Colors of sampling times represent sample groups (blue: oceanic, orange: coastal, gray: mixed). Orange and blue arrows correspond to coastal/mixed and oceanic/mixed waters. For each pair of different time points, it was investigated whether rank increased viruses show higher transcriptional activity compared with rank decreased viruses. Significance was detected by the Mann–Whitney U-tests for each predicted host group (asterisks). The statistical tests were performed on OBV viral genomes whose FPKM values in the virome at the first time point were >10
