Figure 4

Heat map with RAxML tree of dominant OTUs (rbcL gene sequences) within benthic Mesodinium cells from coastal beaches of Korea. The upper phylogeny was constructed based on chloroplast rbcL gene sequences of cryptophytes at the top of the heatmap. Colored branches indicate different cryptophyte genera. Color ranges for the heatmap represent the relative percentage of each OTU in each cell (upper left). The number on the left side of the heatmap means total number of detected OTUs in a single cell.
