Rhizobium Quorum-Sensing Systems Across 142 Genomes

142 complete Rhizobium genomes were analyzed using comparative genomics and phylogenetic reconstruction. The dataset details the distribution and evolution of quorum-sensing systems, including LuxI/LuxR homologs, across chromosomes and plasmids. It was authored by Ivana Blancas-Nava and last updated on 2026-04-17.

Use Cases

• Analyzing the heterogeneous distribution of quorum-sensing systems across bacterial genomes based on the described genomic survey.
• Studying the coevolution of LuxI/LuxR pairs based on the phylogenetic and cophylogenetic analyses mentioned.
• Investigating the role of plasmids as reservoirs for quorum-sensing systems based on the findings of higher diversity and mobility.
• Examining patterns of horizontal gene transfer and genomic rearrangement in bacterial regulatory systems based on the evolutionary framework.

Strengths

• Analysis is based on 142 complete Rhizobium genomes, providing a defined genomic scope.
• Identifies at least seven independent acquisition events for chromosomal quorum-sensing systems.
• Distinguishes between chromosomal and plasmid-encoded systems, highlighting their different evolutionary dynamics.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small (465.4 KB), indicating limited scope or summary-level data.
