Fig. 3: Top 50 differentially expressed genes of the pelagophyte CCMP2097.

Heatmap of clustered results based on normalized and transformed read counts. The functional annotation of each gene is on the right of the heatmap, indicated by diamonds, with each category having a separate color. Note that unknown function genes are indicated as black diamonds. Genes with signal peptides are indicated by filled black circles. The variance stabilizing transformation (vst) is calculated with the vst() function within the DeSeq2 package on R and transforms the count data to normalize the read count. Size factor corresponds to the sequencing depths of each transcriptome. Acronyms: IBP ice-binding protein, Signal P. signal peptide, and SM secondary metabolites.
