Control of Biofilm Formation by an Agrobacterium tumefaciens Pterin-Binding Periplasmic Protein Conserved Among Pathogenic Bacteria

This paper identifies a pterin-responsive regulatory mechanism in Agrobacterium tumefaciens that controls biofilm formation through interactions between PruR, DcpA, and pterins.

An Inducible T7 Polymerase System for High-Level Protein Expression in Diverse Gram-Negative Bacteria

The paper develops a broad host range inducible T7 RNA Polymerase system for high-level protein expression in diverse gram-negative bacteria using IPTG induction.

Motility control through an anti-activation mechanism in Agrobacterium tumefaciens

This study identifies MirA as a protein that blocks flagellar motility in Agrobacterium tumefaciens by sequestering Rem, revealing an anti-activation mechanism regulated by the ExoR-ChvG-ChvI pathway.

Dual adhesive unipolar polysaccharides synthesized by overlapping biosynthetic pathways in Agrobacterium tumefaciens

The paper identifies genes involved in the synthesis of two distinct polysaccharides in Agrobacterium tumefaciens, essential for surface attachment.

Co-Dependent and Interdigitated: Dual Quorum Sensing Systems Regulate Conjugative Transfer of the Ti Plasmid and the At Megaplasmid in Agrobacterium tumefaciens 15955

This study shows that two quorum sensing systems in Agrobacterium tumefaciens co-regulate conjugative transfer of the Ti plasmid and the At megaplasmid through cross-activation and shared regulatory elements.

Destabilization of the tumor-inducing plasmid from an octopine-type Agrobacterium tumefaciens lineage drives a large deletion in the co-resident At megaplasmid

The paper shows that curing a tumor-inducing plasmid in Agrobacterium tumefaciens causes a large deletion in a co-resident megaplasmid, revealing cross-replicon interactions and co-evolution.

Multiple Flagellin Proteins Have Distinct and Synergistic Roles in Agrobacterium tumefaciens Motility

This study investigates the distinct and synergistic roles of multiple flagellin proteins in Agrobacterium tumefaciens motility, showing that FlaA requires other flagellins for functional filament formation.

Reciprocal control of motility and biofilm formation by the PdhS2 two-component sensor kinase of Agrobacterium tumefaciens

This paper investigates how the PdhS2 sensor kinase in Agrobacterium tumefaciens regulates biofilm formation and motility through interactions with DivK and CtrA, affecting cdGMP levels and adhesive polysaccharide production.
