Extended Data Fig. 5: Recurrent patterns in the infection of Prochlorococcus by different cyanophage lineages.
From: Viruses affect picocyanobacterial abundance and biogeography in the North Pacific Ocean

Prochlorococcus abundances are shown in green (top row: a, e, i). Infection levels by all cyanophages combined (black: a, e, i), T4-like (orange: b, f, j), T7-like clade B (blue: c, g, k), and T7-like clade A (red: d, h, l) cyanophages are plotted against the latitudinal position of the cruise track. Northbound and southbound legs of the transects in 2016 and 2017, indicated below the axis, are unfolded on the x-axis as they overlap, and dashed lines indicate the switch in direction between the two transect legs. Date of sample collection is shown as a secondary x-axis. Infection levels are averages determined from 10,000 bootstrapping and resamplings of the cell-to-polony conversion efficiencies (see Methods). The maximum and minimum bounds of infection are represented by error bars. The limit of accurate detection of infection using this assay is <0.05% infection. The location of the hotspot is indicated by yellow shading, sampling occurring northward of the hotspot is indicated by blue shading.
