Evolutionary Relationships through Genome Comparisons

5.8K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

Phylogenetic Trees

41.6K
Phylogenetic trees come in many forms. It matters in which sequence the organisms are arranged from the bottom to the top of the tree, but the branches can rotate at their nodes without altering the information. The lines connecting individual nodes can be straight, angled, or even curved.

Phylogeny

47.2K
Phylogeny is concerned with the evolutionary diversification of organisms or groups of organisms. A group of organisms with a name is called a taxon (singular). Taxa (plural) can span different levels of the evolutionary hierarchy. For instance, the group containing all birds is a taxon (comprising the class Aves), and the group of all species of daisies (the genus Bellis) is a taxon. Phylogenies can likewise include just one genus (i.e., depict species relationships) or span an entire kingdom.

Microbial Phylogeny

Understanding the evolutionary relationships among microorganisms is fundamental to microbial ecology and taxonomy. Phylogenetic trees are essential tools for inferring these relationships, relying primarily on comparative analyses of molecular sequences such as DNA, RNA, or proteins. In microbial studies, these trees typically depict the evolutionary paths of diverse bacterial and archaeal species by mapping genetic differences accumulated over time.Phylogenetic trees are composed of tips,...

Gene Duplication and Divergence

6.8K
The seminal work of Ohno in 1970 popularized the idea of gene duplication and divergence. DNA sequence comparison studies reveal that a large portion of the genes in bacteria, archaebacteria, and eukaryotes was  generated by gene duplication and divergence, indicating its critical role in evolution.
The duplicated copies of the gene are called Paralogs. Paralogs with similar sequences and functions form a gene family. Across several species, a large number of gene families are...

Area of Science:

  • Bioinformatics
  • Computational Biology
  • Evolutionary Biology

Background:

  • Phylogenetic analysis relies on specialized file formats for DNA and amino acid sequences.
  • Existing software struggles to simultaneously handle insertion/deletion (indel) events and data set concatenation.

Purpose of the Study:

  • To develop a novel computational tool for efficient phylogenetic data preparation.
  • To address limitations in current software for coding indels and concatenating sequence alignments.

Main Methods:

  • A Perl script named 2matrix was developed.
  • The script concatenates matrices of non-molecular characters and/or aligned sequences.
  • It also codes inferred insertion/deletion (indel) events within sequence alignments.

Main Results:

  • 2matrix successfully concatenates diverse data types, including molecular sequences and non-molecular characters.
  • The script efficiently codes indel events, a crucial but often challenging aspect of sequence alignment.
  • Output files are compatible with a wide range of popular phylogenetic analysis programs.

Conclusions:

  • 2matrix provides an efficient solution for coding indels and concatenating data matrices.
  • The script enhances the workflow for phylogenetic analyses.
  • 2matrix is freely available as open-source software under the GPL license.
