Amplification of taste receptor T2R1 gene of Takifugu fasciatus.

Fig 2

Relative expression of T2R1 in different tissues of Takifugu fasciatus, A, gill; B, spleen; C, heart; D, lips; E, skin; F, tongue.

Fig 3

The similarities of T2R1 amino acid sequences between T. fasciatus with other animals. Note: the amino acids are numbered along the left and right margin. The transmembrane domains are underlined.

Fig 4

Phylogenetic tree revealing the relationship of T2R1 in T. fasciatus relative to other T2Rs family members of other species. Note: the horizontal branch length is proportional to amino acid substitution rate per site. The numbers represent the frequencies (%) with the tree topology presented was replicated after 1000 iterations.
