Whole-Proteome Tree of Insects: An Information-Theory-Based “Alignment-Free” Phylogeny and Grouping
of “Proteome Books”
Author(s): JaeJin Choi, Byung-Ju Kim and Sung-Hou Kim*
Background: An “organism tree” of insects, the largest and most species-diverse group of all living animals, can be considered as a metaphorical and conceptual tree to capture a simplified narrative of the complex and unpredictable evolutionary courses of the extant insects. Currently, the most common approach has been to construct a “gene tree”, as a surrogate for the organism tree, by selecting a group of highly alignable regions of each of the select genes/proteins to represent each organism. However, such selected regions account for a small fraction of all genes/ proteins and even smaller fraction of whole genome of an organism. During last decades, whole-genome sequences of many extant insects became available, providing an opportunity to construct a “whole-genome or whole-proteome tree” of insects using Information Theory wit..
