Characterization of swimming motility in a marine unicellular cyanobacterium
… and functional significance of the unique swimming motility displayed by some oceanic isolates of the cyanobacterium Synechococcus was investigated. A variety of analytical techniques confirmed that these strains swam through liquids without flagella or flagellar-like appendages. No …

Silver Nanoparticles and the Plant-Associating Abilities of Rhizobiaceae Bacteria
… being the most susceptible. Additionally, swimming motility assays using B. japonicum showed a significant decrease in colony diameter when treated with AgNPs (50 ppm). A significant decrease in root colonization of Triticum aestivum roots by A. brasilense was observed as AgNP treatment …

Antigenic and functional differences between the polar and lateral flagella of Azospirillum brasilense
… the polar flagellum was responsible for free-swimming motility.

Bacterial transport and horizontal gene transfer in subsurface: multiple-scale experimental studies
… affect the dynamics of bacterial deposition and swimming motility reduces bacterial deposition; 3) natural transformation kinetics depend on availability of transforming DNA; 4) extracellular DNA transforms both swimming and swimming-impaired A. vinelandii cells similarly. This work provided …

The role of post-transcriptional regulators in pathogenesis and secondary metabolite production in Serratia sp. ATCC 39006.
… and CarR. Additionally, exoenzyme production and swimming motility were decreased in the ∆hfq mutant, and virulence was attenuated in potato and C. elegans. It was also shown that the phenotype of an hfq mutant is independent of its role in regulating the stationary phase sigma factor, rpoS. In …

Novel regulators of antibiotic biosynthesis in Serratia sp. ATCC 39006
… was also pleiotropic, affecting features such as swimming motility and virulence. Pleiotropy was also found in the intergenic mutant: exhibiting enhanced antibiotic synthesis, and modified motility and virulence capacity. This intergenic insertion then led to the study of VfmE, an AraC-family …

DISCLOSING THE ROLE OF ROOT EXUDATES IN MODULATING THE INTERACTION BETWEEN PLANT AND XENOBIOTIC DEGRADING BACTERIA
… potential and increased biofilm formation, swimming motility and chemoattraction, features overall implicated in the early root colonization. However, other non-flavonoids molecules seemed to be involved in later stages of colonization and supported the plant growth promotion effect induced …

The interplay between pathogenic bacteria and bacteriophage Chi: New directions in motility and phage-host interactions in Enterobacterales
… motile bacteria through their surroundings via swimming motility, or on surfaces via swarming motility. The flagellum is a key virulence factor for motile pathogenic bacteria. Viruses that infect bacteria via this appendage are known as flagellotropic or flagellum-dependent bacteriophages. Much …

The little engine that could: Characterization of noncanonical components in the speed-variable flagellar motor of the symbiotic soil bacterium Sinorhizobium meliloti
… and uses its coupled chemotaxis and flagellar motility systems to search for host plant roots to colonize. Following root colonization, the bacterium converts to a nitrogen-fixing factory for the plant and the combined influences of this symbiosis can quadruple the yields of the host. This …

Novel pleiotropic regulators of gas vesicle biogenesis in Serratia
… (car) and prodigiosin. It displays different motility mechanisms, such as swimming and swarming aided by flagellar rotation and biosurfactant production. In addition, S39006 produces gas vesicles to float in aqueous environments and enable colonization of air-liquid interfaces. Gas vesicles …
