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...

Multi-species Conserved Sequences

Multi-species Conserved Sequences

Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale studies have provided new insights into the evolutionary relationship between organisms.
Although the genome of each species varies greatly from each other, a few sequences are highly conserved. Such conserved DNA...

Maxam-Gilbert Sequencing

Maxam-Gilbert Sequencing

In the same year as the discovery of the Sanger sequencing method, another group of scientists, Allan Maxam and Walter Gilbert, demonstrated their chemical-cleavage method for DNA sequencing. The Maxam-Gilbert method relies on using different chemicals that can cleave the DNA sequence at specific sites, the separation of resulting DNA fragments of variable size using electrophoresis, and deciphering the DNA sequence from the resulting gel bands.

Area of Science:

Bioinformatics
Computational Biology
Environmental Science

Background:

Data integration is a significant hurdle in analyzing environmental sequences.
A unified approach is needed for taxonomic and functional analysis of diverse data types.

Purpose of the Study:

To extend the widely used MEGAN (MEtroGENome ANalyzer) program for integrated analysis.
To introduce MEGAN4, a tool supporting taxonomic and functional analysis of metagenomic, metatranscriptomic, metaproteomic, and rRNA data.

Main Methods:

Utilized NCBI taxonomy for taxonomic analysis.
Employed SEED classification (subsystems, functional roles) and KEGG classification (pathways, enzymes) for functional analysis.
Enabled import and comparison of classification results from other tools.

Main Results:

MEGAN4 provides a unified framework for analyzing multiple environmental sequencing data types.
Demonstrated the capability to perform integrated taxonomic and functional analyses.
Showcased the flexibility to incorporate external analysis results.

Conclusions:

MEGAN4 offers a comprehensive solution for the integrated analysis of environmental sequence data.
The tool facilitates a deeper understanding of microbial community composition and function.
MEGAN4 is freely available for academic use across major operating systems.
