Expression of organelle genes. Heatmap of the expression of polypeptide 1 of cytochrome c oxidase (COX1) and the large subunit of ribulose-1,5-bisphosphate carboxylase oxygenase (rbcL) across the transect. Reads to each gene within the taxonomic categories are normalized for the total number of reads (for a given gene) across the entire transect. Note the log scale (reads (taxonomic lineage rbcL at one site)/reads (all rbcL)).
