A heatmap of gene expression (fragment per kilobase of transcript per million reads (FPKM)) for enzymes involved in tetrapyrrole synthesis in Ochromonas sp. in different treatments. Expression for each treatment was the average between the 3 replicates. Blue letters indicate enzyme abbreviations (Refer to Additional file 7: Table S5 for the full name of each enzyme). An asterisk next to the enzyme abbreviation indicates that there were multiple paralogs for the enzyme, in which case the expression value was calculated as the geometric mean of expression for all paralogs (Refer to Additional file 6: Table S4 for the expression values of each paralog)
