FIG. 4.
Confocal laser scanning micrographs of a mat section (consistent with the mat sample shown in Fig. 3A, C, and E) hybridized with horseradish peroxidase-labeled probes specific for methanotrophic ANME-1 (green) and ANME-2c (blue) archaea. (A) Profile through the mat. The depth below the mat surface is indicated on the left. (B to G) Close-ups of ANME-1 and ANME-2c distributions and aggregations at different depths of the mat. Scale bars = 10 μm.
