90(6):e0076024.
PMID: 38775579
Motile plant-associated bacteria use chemotaxis and dedicated chemoreceptors to navigate gradients in their surroundings and to colonize host plant surfaces. Here, we characterize a chemoreceptor that we named Tlp2 in...

Plant Direct
. 2023 Nov;
7(11):e544.
PMID: 38028650
Poplar is a short-rotation woody crop frequently studied for its significance as a sustainable bioenergy source. The successful establishment of a poplar plantation partially depends on its rhizosphere-a dynamic zone...

J Bacteriol
. 2023 May;
205(6):e0048422.
PMID: 37255486
Chemotaxis in and depends on the presence of hexagonal polar arrays composed of membrane-bound chemoreceptors that interact with rings of baseplate signaling proteins. In the alphaproteobacterium Azospirillum brasilense, chemotaxis is...

Mol Microbiol
. 2022 Jul;
118(3):223-243.
PMID: 35808893
The bacterial flagellum is a complex macromolecular machine that drives bacteria through diverse fluid environments. Although many components of the flagellar motor are conserved across species, the roles of FliL...

Melchionna M, Gullett J, Bouveret E, Shrestha H, Abraham P, Hettich R, et al.
J Bacteriol
. 2022 Mar;
204(4):e0058321.
PMID: 35285724
Membrane potential homeostasis is essential for cell survival. Defects in membrane potential lead to pleiotropic phenotypes, consistent with the central role of membrane energetics in cell physiology. Homologs of the...

Ganusova E, Vo L, Mukherjee T, Alexandre G
Front Microbiol
. 2021 May;
12:664826.
PMID: 33968002
Bacterial chemotaxis is the directed movement of motile bacteria in gradients of chemoeffectors. This behavior is mediated by dedicated signal transduction pathways that couple environment sensing with changes in the...

mSystems
. 2021 Feb;
6(1).
PMID: 33594007
Bacterial chemotaxis affords motile bacteria the ability to navigate the environment to locate niches for growth and survival. At the molecular level, chemotaxis depends on chemoreceptor signaling arrays that interact...
