Fig. 6. Viral enrichment in slick versus non-slick SML, and auxiliary metabolic genes.

Fig. 6

Enrichment of viruses in slick SML and non-slick SML across different filtered fractions. Shown are coverage ratios >1 indicating enrichment of a virus in the SML compared to the corresponding reference subsurface water sample. Black areas indicate depletion of a virus (ratio <1), while white areas show absence of the virus in the nominator or denominator of the ratio. Values and VCs of the heatmap’s y-axis are given in Table S8a (a). Coverage of vOTUs carrying an auxiliary metabolic gene (AMG), sorted by KEGG category (b). Only vOTUs being present in a sample based on read mapping were considered for this analysis. Full information on involved AMGs is given in Table S8b. FL free-living fraction (5–0.2 µm), PA particle-associated fraction (>5 µm), SML sea-surface microlayer, SSW subsurface water, Vir viral fraction (<0.2 µm).
