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...

Area of Science:

Bioinformatics
Computational Biology
Ecology

Background:

Next-generation sequencing (NGS) offers high output and reduced costs for genomic analyses.
The 454 GS-FLX platform is increasingly used for biodiversity surveys via amplicon sequencing.
A lack of user-friendly software hinders NGS application in biodiversity research.

Purpose of the Study:

To develop an integrated, user-friendly software utility for processing amplicon sequencing data in biodiversity surveys.
To address the need for automated quality control, primer removal, and data preparation for downstream analysis.

Main Methods:

Developed CANGS (Cleaning and Analyzing Next Generation Sequences), a Perl-based software utility.
Implemented modules for filtering low-quality sequences and removing PCR primers.
Integrated functions for singleton filtering, barcode identification, and generating input files for analyses.

Main Results:

CANGS automates critical steps in next-generation sequencing data processing for biodiversity studies.
The software links sequence data to the closest taxonomic references in the NCBI database.
It generates analysis-ready files for common tools like rarefaction analyses.

Conclusions:

CANGS provides a flexible and user-friendly solution for amplicon-based biodiversity surveys.
The software facilitates taxonomic assignment and sequence divergence analysis.
It is adaptable to various amplicon sizes, primer sequences, and quality thresholds, benefiting non-bioinformaticians.
