Figure 2.

Phylogeny of algal genes identified in Ciona. Numbers above branches show bootstrap values for maximum likelihood and distance analyses respectively. Asterisks indicate values lower than 50%. Other bootstrap values below 50% in both methods are not shown. Red: tunicates; green: Plantae; blue: cyanobacteria; pink: other plastid-containing eukaryotes. (A) Taurine dioxygenase; (B) cytidine monophospho-N-acetylneuraminic acid synthetase; (C) arginine N-methyltransferase 7; and (D) peptidylglycine alpha-hydroxylating monooxygenase.
