Analysis of DNA samples from known eukaryotes. (a) 18S rRNA gene amplicons. (b) ITS rRNA gene amplicons. The sample tested is listed along the x-axis. The y-axis shows the level of taxonomic placement of each OTU in each sample relative to the correct taxon indicated on the x-axis. The numbers of sequence reads are shown by the size of the point. Thus, large circles high up on the y-axis indicate correct placement of the major taxa.
