for QseBC regulation of motility and virulence was proposed by Guckes et al [25] involving cross - regulation with the PmrAB TCS. PmrAB detects extracellular iron [26] and is involved in resistance to polymyxin ...
and Photobacterium (Supplementary Table S1). Fifty-one genomes were obtained from isolates from two different aquatic systems within CCB, Churince and Pozas Rojas in Los Hundidos system (Fig. 1). Four Pseudomonas ...
as a transcriptional regulator . (B) A Gram-negative two-component QS system . Autoinducer molecules are produced by the AI synthase, released into the extracellular environment, and are then detected by a transmembrane ...
Abstract Many bacteria acquire dissemination and virulence traits in G1-phase. CtrA, an essential and conserved cell cycle transcriptional regulator identified in the dimorphic alpha-proteobacterium ...
and toxins, the production of adhesins and biofilm matrix components, the regulation of different forms of cell motility , as well as cell cycle progression [2], [4]. Receptor affinities were reported from ...
successful colonization of host plants (Peyraud et al., 2019). QS between pathogenic microbes leads to an increase in virulence and pathogenicity in the host plant. QS-based systems of the Pseudomonas ...
such as Pseudomonas aeruginosa or Stenothrophomonas maltophilia or two-component regulators , with special relevance in Aeromonas spp., along with other pathways. Likewise, the multiple mutational mechanisms leading ...
, as host cells are damaged they release iron in the form of haem and haemoglobin, from which P. aeruginosa can sequester iron using the haem assimilation system (Has) and Phu ( Pseudomonas haem uptake ...
from the adventitious cross -talk between two transcription factors. One of these factors, the C protein of the incoming R–M system reduced expression of RacR, the essential regulator of the cryptic Rac ...
environmental inputs and controlling the motile –sessile transition in both directions, it seems highly likely that c-di-GMP signalling is important in these mixed-species biofilms colonising cooling water systems ...
