AI-2 Production in Fusobacterium nucleatum Is Subspecies-Specific and Uncoupled from Quorum Sensing

This study shows AI-2 production in Fusobacterium nucleatum is subspecies-specific and not linked to quorum sensing.

The Gene Encoding Ornithine Decarboxylase for Putrescine Biosynthesis Is Essential for the Viability of Fusobacterium nucleatum

This study shows that the oda gene, which encodes ornithine decarboxylase for putrescine biosynthesis, is essential for the viability of Fusobacterium nucleatum under anaerobic conditions.

The CarSR Two-Component System Directly Controls radD Expression as a Global Regulator that Senses Bacterial Coaggregation in Fusobacterium nucleatum

This study identifies the CarSR two-component system as a direct regulator of radD in Fusobacterium nucleatum, revealing its role in sensing coaggregation and regulating adhesion.

Development of a Conditional Plasmid for Gene Deletion in Non-Model Fusobacterium nucleatum strains

This paper develops a conditional plasmid system for gene deletion in non-model Fusobacterium nucleatum strains, successfully generating mutants in multiple subspecies and related species.

Development of SacB-based Counterselection for Efficient Allelic Exchange in Fusobacterium nucleatum

This paper develops a SacB-based counterselection method for efficient allelic exchange in Fusobacterium nucleatum, enabling unmarked gene mutations without requiring a modified host.
