a Nucleotide diversity and average SNV frequencies (per 1000 base pairs) of viruses at different cyanobacterial blooming stages. b Spearman correlation between viral nucleotide diversity or SNV and environmental factors. Asterisks indicate statistically significant differences between sampling stages (*p < 0.05; **p < 0.01; ***p < 0.001; ns: p > 0.05). c Linear regression between viral nucleotide diversity and host abundance. Host genera infected by viruses with nucleotide diversity above the 95% quantile threshold are specifically labeled. d Proportion of viral genes under positive selection (pN/pS > 1) or under purifying selection (pN/pS < 1). e Number of positively selected genes encoded by viruses that infect specific bacterial genera.
