The effect of DNA extraction kits on the community composition. (A) Heat map of 20 most abundant OTUs in bacterial and eukaryotic plankton dataset. (B) Variation of main high-rank taxa of bacterial and eukaryotic plankton within each of DNA extraction kit. Statistical analysis is non-parametric Kruskal-Wallis test. P < 0.05. Each OTU or high-rank taxon is in a row, and color intensity indicates its average relative abundance of each DNA extraction kit (n = 3).
