Phylogenetic tree of diatom γ-tubulins. A total of 40 sequences were used to build aMaximum Likelihood tree using the LG + F + I + G4 substitution model. The amino acids conserved in diatoms are on the left, characteristic amino acids of certain γ-tubulin groups are on the right. Large taxa are highlighted in color: green, Coscinodiscophyceae; red, Mediophyceae; blue, Bacillariophyceae, Fragilariophycidae; purple, Bacillariophyceae, Bacillariophycidae.
