Figure 2
Plot visualising shared and unique orthologous protein groups across four species of crustose coralline algae, Lithophyllum, Sporolithon, Porolithon, and Lithothamnion, and two species of noncalcified red algae, G. chorda and C. crispus. Plot at the top shows the number of orthogroups found in the species indicated in the schematic below. Shared orthogroups across all red algae species are highlighted in purple, across only CCA species in red, and across only the noncalcifying red algal species in blue. Orthologous proteins were identified with Orthofinder and plotted using the R package, UpsetR75. Any relationships with <15 orthogroups were omitted.
