Method for filtering, evolving and classifying proteome and system thereof

Abstract

The invention discloses a method for filtering, evolving and classifying proteome and a system thereof. The method comprises the following steps of: an original data acquiring step: acquiring the genome data and the proteome data (S110) of species to be classified; a predicting step: predicting a transversal transfer gene (S120) in a genome sequence based on the genome data; a filtering step: filtering a proteome sequence (S130) corresponding to the transversal transfer gene in the proteome based on the proteome data and the transversal transfer gene; a calculating step: calculating the evolving distance (S140) between the species with the filtered proteome sequence; and an inferring step: inferring a phylogeny relation (S150) between the species by utilizing the evolving distance between the species. According to the invention, existing interference information which is caused by transversal gene transfer during deducing a biogenesis process can be eliminated so that the deduced biogenesis process is more accurate to provide a more reliable classification basis for biological evolution and classification.

Description

technical field [0001] The invention relates to a proteome filtering evolution classification method and a system thereof. Background technique [0002] At present, in the field of bioevolutionary research, there are techniques for predicting horizontally transferred genes in the genome, quantifying the distance of traits between biological species, and inferring overlay trees. There are many kinds of these three types of technologies at present, but they are relatively independent three types of technologies. In the current biological phylogenetic research and biological taxonomy research, the traditional methods of constructing phylogenetic relationships between species are to combine the latter two types of technologies. Combined, but did not see the internal relationship between the first type of technology and the latter two types of technology in the biological sense. In recent years, research on the phenomenon of horizontal gene transfer between species genomes has sh...

There are many kinds of these three types of technologies at present, but they are relatively independent three types of technologies. In the current biological phylogenetic research and biological taxonomy research, the traditional methods of constructing phylogenetic relationships between species are to combine the latter two types of technologies. Combined, but did not see the internal relationship between the first type of technology and the latter two types of technology in the biological sense. In recent years, research on the phenomenon of horizontal gene transfer between species genomes has shown that the existence of horizontally transferred genes has a significant impact on biological phylogenetic relationships. The reconstruction of phylogeny has obvious interfe
