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...

Comparing Mitochondrial, Chloroplast, and Prokaryotic Genomes

Comparing Mitochondrial, Chloroplast, and Prokaryotic Genomes

The present-day mitochondrial and chloroplast genomes have retained some of the characteristics of their ancestral prokaryotes and also have acquired new attributes during their evolution within eukaryotic cells. Like prokaryotic genomes, mitochondrial and chloroplast genomes neither bind with histone-like proteins nor show complex packaging into chromosome-like structures, as observed in eukaryotes. Unlike mitotic cell divisions observed in eukaryotic cells, mitochondria and chloroplasts...

Genomic DNA in Eukaryotes

Genomic DNA in Eukaryotes

Eukaryotes have large genomes compared to prokaryotes. To fit their genomes into a cell, eukaryotic DNA is packaged extraordinarily tightly inside the nucleus. To achieve this, DNA is tightly wound around proteins called histones, which are packaged into nucleosomes that are joined by linker DNA and coil into chromatin fibers. Additional fibrous proteins further compact the chromatin, which is recognizable as chromosomes during certain phases of cell division.

Genomics

Genomics

Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Genomic DNA in Prokaryotes

Genomic DNA in Prokaryotes

The genome of most prokaryotic organisms consists of double-stranded DNA organized into one circular chromosome in a region of cytoplasm called the nucleoid. The chromosome is tightly wound, or supercoiled, for efficient storage. Prokaryotes also contain other circular pieces of DNA called plasmids. These plasmids are smaller than the chromosome and often carry genes that confer adaptive functions, such as antibiotic resistance.

Evolution of Microbial Genome

Evolution of Microbial Genome

Microbial genome evolution is a highly dynamic process shaped by continual gene gain and loss across species and strains. This genomic flexibility allows microorganisms to adapt rapidly to environmental pressures and interactions with other organisms. Central to understanding this diversity is the distinction between the core and pan genomes.The core genome comprises the genes shared by all sampled strains of a species, representing essential functions needed for fundamental cellular processes.

Area of Science:

Comparative Genomics
Evolutionary Biology
Bioinformatics

Background:

Comparative genomic visualization is crucial for understanding gene organization and genome evolution.
Existing tools often lack broad taxonomic coverage or detailed evolutionary analysis features.
The Genomicus database previously focused on vertebrates, limiting its scope.

Purpose of the Study:

To extend the Genomicus database to include four new eukaryotic clades: plants, non-vertebrate metazoa, protists, and fungi.
To enhance comparative genomic visualization capabilities for evolutionary phylogenomics.
To provide tools for analyzing gene gain/loss, duplications, and locus evolution.

Main Methods:

Expansion of the Genomicus database to incorporate genomic data from plants, non-vertebrate metazoa, protists, and fungi.
Development and description of graphical modules for visualizing comparative genomic information.
Utilizing homology relationships to reconstruct ancestral gene orders and analyze evolutionary events.

Main Results:

The Genomicus database now supports comparative genomic visualization across >150 eukaryote genomes.
The tool effectively reveals differential gene loss and gain events.
Segmental and whole-genome duplications, as well as locus evolution, can be studied through the graphical modules.

Conclusions:

The extended Genomicus database provides a powerful, user-friendly platform for evolutionary phylogenomics.
It facilitates the exploration of gene organization and genome evolution across a wide range of eukaryotes.
Genomicus is a valuable resource for discovering evolutionary patterns such as gene duplication and loss.
