Rhizobium Quorum-Sensing System Diversity and Evolution from 142 Genomes

A research paper analyzing the diversity and evolution of quorum-sensing systems in Rhizobium bacteria. The study examined 142 complete Rhizobium genomes using comparative genomics, phylogenetic reconstruction, and genomic context analysis. The work was authored by Ivana Blancas-Nava and last updated in April 2026.

Use Cases

• Study the distribution of LuxI/LuxR homologs across bacterial genomes based on the comparative genomics analysis
• Analyze the coevolution of LuxI/LuxR pairs using the described cophylogenetic approaches
• Investigate the role of plasmids in horizontal gene transfer of quorum-sensing systems as highlighted in the findings
• Examine genomic contexts associated with chromosomal quorum-sensing systems, supporting at least seven independent acquisition events

Strengths

• Analysis is based on 142 complete Rhizobium genomes, providing a substantial genomic sample
• Study identifies at least seven independent acquisition events for chromosomal quorum-sensing systems
• Findings are detailed in a formal research paper, suggesting peer-reviewed methodology

Limitations

• The dataset is a 210.3 KB PDF, which is a small research document rather than a primary data repository
• Row count and column-level documentation for underlying genomic data are unknown
• Description metadata is limited; actual data quality requires manual inspection after download
