Figure 3. Maximum-likelihood (ML) phylogenetic tree was reconstructed based on the concatenated 13 protein-coding genes of R. szechuanensis and other 22 Gobionellinae fishes. Accession numbers were indicated after the species names. Numbers at the nodes indicated bootstrap support values from 1000 replicates.
