Quorum-Sensing System Diversity in 142 Rhizobium Genomes

142 complete Rhizobium genomes were analyzed to understand the distribution and evolution of quorum-sensing systems. The study by Ivana Blancas-Nava, published in 2026, used comparative genomics and phylogenetic reconstruction. It found plasmid-encoded systems exhibit substantially greater diversity and act as major reservoirs for horizontal gene transfer.

Use Cases

• Phylogenetic analysis of LuxI/LuxR homologs based on sequence similarity and domain architecture mentioned in the description
• Comparative genomics to study the heterogeneous distribution of quorum-sensing systems across bacterial replicons
• Cophylogenetic approaches to assess coevolution and partner recruitment among LuxI/LuxR pairs
• Genomic context analysis to identify at least seven independent acquisition events of chromosomal systems

Strengths

• Analysis is based on 142 complete Rhizobium genomes, providing a broad genomic sample
• Findings detail at least seven independent acquisition events for chromosomal quorum-sensing systems
• Dataset is associated with a detailed scientific study employing multiple methods like phylogenetic reconstruction and genomic context analysis

Limitations

• The primary data file is an 81.3 KB PDF; underlying genomic data tables are not directly provided
• Row count and column-level documentation for any underlying data are unknown
• Freshness should be verified as the last update is dated 2026-04-17
