MicrobesOnline offers a comprehensive resource for microbial genomics, featuring over 1000 genomes and expression data. Future updates will include comparative metagenomic analysis for enhanced microbial genome exploration.
Area of Science:
- Microbial Genomics
- Bioinformatics
- Comparative Genomics
Background:
- MicrobesOnline has served as a community resource for comparative and functional genome analysis since 2003.
- The portal hosts over 1000 complete microbial genomes (bacteria, archaea, fungi) and thousands of expression microarrays.
Purpose of the Study:
- To provide a centralized platform for analyzing microbial genome data.
- To facilitate gene annotation, evolutionary history reconstruction, and identification of co-regulated genes.
- To offer tools for phylogenetic analysis, metabolic pathway comparison, and sequence analysis.
Main Methods:
- Comparative genome browsing based on phylogenetic trees.
- Gene searching by expression profile.
- Identification and conservation analysis of regulatory motifs.
- Phylogenetic profile searches and comparative pathway views.
Main Results:
- The platform integrates diverse microbial genomic data, including genomes and expression data.
- Tools are available for phylogenetic analysis, gene co-regulation identification, and metabolic pathway comparison.
- The resource supports sequence analysis and integrates with other microbial genome databases.
Conclusions:
- MicrobesOnline is a valuable resource for researchers in microbial genomics and bioinformatics.
- The platform facilitates comparative genome analysis and functional genomics studies.
- Upcoming updates will enhance capabilities with metagenomic data analysis.
