Bioinformatics tools for quantitative and functional metagenome and metatranscriptome data analysis in microbes

Area of Science:

• Microbiology
• Bioinformatics
• Genomics

Background:

• Metagenomic and metatranscriptomic sequencing are increasingly used to associate microbiota with diseases and ecological shifts.
• Current analyses often focus on species-level profiling, but strain-level analysis offers deeper insights into specific microbial relationships.
• Metatranscriptomics reveals gene expression, providing crucial information on microbial activity.

Purpose of the Study:

• To review existing bioinformatics tools for metagenomic and metatranscriptomic data analysis.
• To guide researchers in selecting appropriate tools for their microbiome studies.
• To introduce an Integrated Meta-Function mapping pipeline for accelerated functional gene analysis.

Main Methods:

• Literature review of current bioinformatics tools for microbiome data analysis.
• Development of an Integrated Meta-Function mapping pipeline.
• Evaluation of the pipeline's efficiency in incorporating reference databases and accelerating gene mapping.

Main Results:

• A comprehensive summary of available bioinformatics tools for analyzing metagenomic and metatranscriptomic data.
• The proposed Integrated Meta-Function pipeline effectively integrates diverse reference databases.
• The pipeline significantly accelerates functional gene mapping for both metagenomic and metatranscriptomic datasets.

Conclusions:

• Combining metagenomic and metatranscriptomic analyses is vital for understanding microbial gene activity, such as drug resistance.
• The developed pipeline offers a valuable resource for researchers to efficiently map functional genes in microbiome studies.
• This work aids in advancing the understanding of host-microbe interactions and their role in health and disease.
