[i] See Table 1 for abbreviations of species names.

[ii] Numbers in parentheses indicate the number of coding modules for that particular rRNA species.

[iii] Mitochondrially-encoded tRNAs unique toScenedesmus are in bold and marked with an asterisk; the codons they read and the amino acids they specify are also set in bold.

[iv] Transfer RNA coded for by a duplicated gene.
