Phylogenetic tree genes

For selected GPCR gene sequences the phylogenetic trees were constructed by using ClustalW (13) and TreeView (14) programs. 

Clicking the phylogenetic map button links the user to the phylogenetic tree viewer of all GPCR genes of Level A. The branch color can be selected according to subfamily or chromosomal number. 

By clicking submit bottun, after the AND combinations of several conditions, the content search area retrieve the selected GPCR genes that again appear on the chromosomal viewer, the phylogenetic tree viewer, and the lower scroll list page. 

So much gene transfer between organisms has occurred that it is difficult to establish the earliest parts of a phylogenetic tree of the type shown in Fig. 1-5. Another factor that confuses our study of bacteria is that less than 1% of all living microorganisms have been grown in pure cultures.355 356... 

Fig. (7). Phylogenetic relationship of tomato subtilases. An unrooted phylogenetic tree is shown based on the amino acid sequences deduced from tomato subtilase genes and cDNAs. Numbers indicate PAM distances (accepted point mutations per 100 residues) between sequences. The figure was modified after (8).
