Fig. 3: The global distribution of cyanopodovirus clades.
From: Abundant and cosmopolitan lineage of cyanopodoviruses lacking a DNA polymerase gene
A. Relative abundances of the four cyanopodovirus clades in surface waters. Cyanophages in the MPP-A, -B, and -C clades were indicated in pink, blue, and orange, respectively. P-RSP2–like cyanophages were indicated in grey. The size of a pie chart represented the overall recruitment frequency of the cyanopodovirus population in a sampling site, expressed as the total recruited nucleotides of reads (kb) per kb of viral genome per Gb of virome dataset (KPKG). B. The proportions of different cyanopodovirus clades in sampling sites from surface (SRF, 46 sites), deep chlorophyll maximum and the bottom of mixed layer when no deep chlorophyll maximum (DCM + Mix, 33 sites in total). C. Comparison of recruitment frequency of cyanopodovirus clades in the SRF and DCM + Mix sites. Analyses were performed for the 29 sites where both SRF and DCM/Mix waters were sampled. Recruitment frequency was displayed as log10(KPKG + 1). Paired t-tests were applied to compare SRF and DCM + Mix samples: * for p < 0.05, ** for p < 0.01, *** for p < 0.001, and ns for no significance.
