There have been a number of recent attempts to develop methodologies that do not require sequence alignment for deriving species phylogeny based on overall similarities of the complete genomes. The mitochondrial genomes have provided much information on the evolution of this organelle and have been used for phylogenetic reconstruction by various methods with or without sequence alignment. In this paper we introduce three fast algorithms, namely, dynamical language model with correlation distance, Fourier transform with Kullback-Leibler divergence distance, log-correlation distance, for deriving vertebrate phylogeny based on mitochondrial genomes. The distance-based analyses show that the mitochondrial genomes are separated into three major clusters corresponding to mammals, fish, and Archosauria (including birds and reptiles)respectively. The interrelationships among the mitochondrial genomes are roughly in agreement with the current understanding on the phylogeny of vertebrates revealed by the traditional approaches.
Impact and interest:
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
