The ArcB kinase sensor participates in the phagocyte-mediated stress response in Salmonella Typhimurium [PDF]

Frontiers in Microbiology
The ArcAB two-component system includes a histidine kinase sensor (ArcB) and a regulator (ArcA) that respond to changes in cell oxygen availability. The ArcA transcription factor activates genes related to metabolism, membrane permeability, and virulence,

Divergent litter traits of riparian plant species between humid and drier biomes within the tropics

Ecography, Volume 2023, Issue 2, February 2023., 2023
Riparian forests provide abundant plant litter – mostly in the form of dead leaves (hereafter litter) – for both forest soils and adjacent stream ecosystems, supporting terrestrial and aquatic detritus‐based food webs. Although the fate of litter is predominantly dependent on its chemical and physical traits, there is limited availability of data on ...
