Phylogenetic Trees

Phylogenetic Trees

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.The length of the branches can depict time or the relative amount of change among organisms. For instance, the branch length might indicate the number of amino acid changes in the sequence that underlies the...

Microbial Phylogeny

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,...

Evolutionary Relationships through Genome Comparisons

Evolutionary Relationships through Genome Comparisons

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...

Phylogeny

Phylogeny

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...

The Tree of Life - Bacteria, Archaea, Eukaryotes

The Tree of Life - Bacteria, Archaea, Eukaryotes

The “tree of life” describes the evolution of life and the evolutionary relationships between organisms. The root of the tree is the common ancestor to all life on Earth. All other species radiate from this point, much like the branches of a tree. The numerous tips of these branches on the tree of life represent every living, or extant, species. Extinct species, which are species that no longer exist, can be found towards the center of the tree. Currently, these organisms, both extant and...

Background:

The exponential growth of phylogenetic data necessitates advanced bioinformatic tools for efficient storage and retrieval.
Existing tools lack the capability to identify specific taxa within phylogenetic trees or compare phylogenetic hypotheses.

Purpose of the Study:

To develop an intelligent search engine for phylogenetic databases.
To enable users to perform both taxonomic and phylogenetic queries on existing tree data.

Main Methods:

Implementation of PhyloFinder as an intelligent search engine utilizing TreeBASE.
Development of taxonomic query functions, including exact name matching, synonym handling, and spelling suggestions.
Integration of phylogenetic query capabilities to identify trees containing query trees or similar topologies.

Main Results:

PhyloFinder successfully identifies trees containing specified taxa, including synonyms, ancestors, and descendants.
The tool performs phylogenetic queries, locating trees with matching or similar topologies to the input hypothesis.
Visualization tools highlight query results and provide links to external databases like NCBI and TBMap.

Conclusions:

PhyloFinder significantly enhances the utility of tree databases through comprehensive taxonomic and phylogenetic search functionalities.
The tool offers valuable visualization features for improved data exploration and interpretation.
An accessible web client application of PhyloFinder, using TreeBASE data, is available for public use.
