Overview of phylogenetic expression profiling approach and data. a 18S-based cladogram of the species in this study. b Overview of our approach for inferring ortholog groups from RNA-seq transcripts (see also Methods and Supplementary Figure 1). c Heatmap of expression levels of the 4219 genes and 657 samples analyzed in this study. Samples and genes are clustered hierarchically. Color bar near the top shows the phylum of each sample, matching the colors in a
