Association between the abundance of Chlorobium and the abundance of its potential viruses. Line graph depicting the contig read depth of Chlorobium (black line) and the expanded CL1024 cluster (green circle), expanded SG14554 singleton (yellow triangle), CL248 (orange diamond), and CL400 (grey square) in the metagenomes from the three filter fractions (3, 0.8, and 0.1 μm) from the interface (I) and neighbouring depths (upper 3, U3; lower 1, L1). The metagenomes represent summer (Dec. 2006 and Dec. 2014), winter (Jul. 2014 and Aug. 2014; L1 was not sampled in winter), and spring (Nov. 2008, Nov. 2013, and Oct. 2014). Filter sizes: 3, 20–3 μm; 0.8, 3–0.8 μm; 0.1, 0.8–0.1 μm
