Fig. 6.

Phylogenetic relationships and chromosomal clustering of mouse Tas2r genes. Gene symbols are colored in red, green or blue to indicate whether their expression pattern is broad, intermediate or restricted, respectively, as assessed in the qRT-PCR profiling. Unlabelled gene symbols indicate that no expression was detected for these genes. The phylogenetic tree (a) was generated from the coding sequences of the 35 mouse Tas2r genes with the program AlignX of the software package Vector NTI using the Kimura correction option. The chromosomal position (b) of each gene in the corresponding band was assessed with www.ncbi.nlm.nih.gov/gene. Pictures of mouse chromosomes were taken from www.pathology.washington.edu
