Figure 7
Evolution of the coronin protein family with respect to the species evolution. Schematic representation of the most widely accepted eukaryotic tree of life. Branch lengths are arbitrary. The coronin inventories of certain taxa and specific species have been plotted to the tree with class numbers given in colour-coded boxes. "O" stands for "Orphan", the unclassified short coronins. The numbers on the arrows refer to alternative placing of the respective taxa: 1: The independence of the Diplomonadida (instead of grouping them to the superkingdom Excavata) is supported by [51]. 2: The monophyly of the Rhodophyta is supported by [28, 55]. 3: Grouping the Haptophyceae and Cryptophyta to the SAR is supported by [55–57].
