Sticking together: building a biofilm the Bacillus subtilis way
Biofilms are ubiquitous communities of tightly associated bacteria encased in an extracellular matrix. Bacillus subtilis has long served as a robust model organism to examine the molecular mechanismsExpand

Bacillus subtilis biofilm induction by plant polysaccharides
Significance The plant growth-promoting bacterium Bacillus subtilis is frequently found associated with plant roots where it protects plants from infection. Here, we demonstrate that B. subtilis rootExpand

Bistability and biofilm formation in Bacillus subtilis
Biofilms of Bacillus subtilis consist of long chains of cells that are held together in bundles by an extracellular matrix of exopolysaccharide and the protein TasA. The exopolysaccharide is producedExpand

Agrobacterium Bioassay Strain for Ultrasensitive Detection of N-Acylhomoserine Lactone-Type Quorum-Sensing Molecules: Detection of Autoinducers in Mesorhizobium huakuii
ABSTRACT An ultrasensitive bioassay system for the detection of N-acylhomoserine lactones (AHLs) was constructed in Agrobacterium tumefaciens by using the T7 expression system to overproduce the AHLExpand

An epigenetic switch governing daughter cell separation in Bacillus subtilis.
Growing cells of Bacillus subtilis are a bistable mixture of individual motile cells in which genes for daughter cell separation and motility are ON, and chains of sessile cells in which these genesExpand

A novel regulatory protein governing biofilm formation in Bacillus subtilis
Production of an extracellular matrix is a hallmark of biofilm formation. In the spore‐forming bacterium Bacillus subtilis, the matrix consists of an exopolysaccharide, which is specified by theExpand

A combination of glycerol and manganese promotes biofilm formation in Bacillus subtilis via histidine kinase KinD signaling.
The spore-forming bacterium Bacillus subtilis forms matrix-enclosed biofilms in response to environmental cues that to date remain poorly defined. Biofilm formation depends on the synthesis of anExpand

Biocontrol of tomato wilt disease by Bacillus subtilis isolates from natural environments depends on conserved genes mediating biofilm formation.
Bacillus subtilis and other Bacilli have long been used as biological control agents against plant bacterial diseases but the mechanisms by which the bacteria confer protection are not wellExpand

Evidence for cyclic Di-GMP-mediated signaling in Bacillus subtilis.
Cyclic di-GMP (c-di-GMP) is a second messenger that regulates diverse cellular processes in bacteria, including motility, biofilm formation, cell-cell signaling, and host colonization. Studies ofExpand

TrlR, a defective TraR‐like protein of Agrobacterium tumefaciens, blocks TraR function in vitro by forming inactive TrlR:TraR dimers
Octopine‐type Ti plasmids of Agrobacterium tumefaciens require the quorum‐sensing proteins TraR and TraI and the diffusible pheromone 3‐oxooctanoyl homoserine lactone (AAI) to regulate genes requiredExpand
