A 240 KB Excel dataset from figshare, authored by Christy R. Handel and last updated in April 2026. It contains findings from an investigation into N-acyl-homoserine lactone-based quorum sensing systems in underexplored bacterial lineages and environments, including newly described species from Hawai'i and the Bahamas. The data likely includes results from genomic analyses, hidden Markov model searches, and liquid chromatography-mass spectrometry.
Use Cases
- Comparative genomic analysis of luxI/R homologs based on the described phylogenetic and domain architecture findings.
- Studying the ecological role of AHL signaling in underexplored environments like lava caves and hypersaline mats mentioned in the description.
- Modeling the regulatory frameworks of AHL production in Gram-positive Actinomycetota, which the description suggests may differ from canonical systems.
Strengths
- Data is openly licensed under CC-BY-4.0.
- Focus on underexplored environments and bacterial lineages, including newly described species.
- Analysis integrates multiple methods: custom HMMs, phylogenetics, genomics, and LC-MRM-MS.
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 (240 KB), indicating a limited scope of observations.
