It is proposed that TBDR overrepresentation and the presence of CUT loci designate the ability to scavenge carbohydrates, which might play a very important role in the biogeochemical cycling of plant-derived nutrients in marine environments.

This review summarizes the current understanding of the molecular basis of host specificity in the Xanthomonas genus, with a particular focus on the ecology, physiology, and pathogenicity of the bacterium.

An important role for TBDTs and xylan utilization systems for bacterial adaptation in the phyllosphere, oligotrophic environments and animal guts is supported.
Multistress Regulation in Escherichia coli: Expression of osmB Involves Two Independent Promoters Responding either to σS or to the RcsCDB His-Asp Phosphorelay

Escherichia coli osmB appears as another example of a multistress-responsive gene whose transcription involves both a sigma(S)-dependent promoter and a second one independent of s Sigma(S) but controlled by stress-specific transcription factors.

The results of transport experiments suggest that GlcNAc passively diffuses through the bacterial envelope, an observation that calls into question whether GlCNAc is a natural substrate for these TonB-dependent active transporters and consequently is the source of Glc NAc for this nonchitinolytic plant-associated bacterium.

The results provide the first direct evidence that levels of BVGA∼P in vivo correspond temporally to the expression of early and late BvgA‐regulated virulence genes, as well as a number of other aspects of Bvg a function predicted from previous studies and by analogy with other two‐component response regulators.

The results extend the range of sources of GlcNAc metabolized by this phytopathogenic bacterium during its life cycle to include chitooligosaccharides that could originate from fungi or insects present in the plant environment, muropeptides leached during peptidoglycan recycling and bacterial lysis, and N-glycans from plant N- glycosylated proteins present inThe plant cell wall as well as in xylem sap.

This study constitutes the first evidence suggesting N-glycopeptide degradation by a plant pathogen, a feature shared with human pathogenic bacteria.
Insights into the Extracytoplasmic Stress Response of Xanthomonas campestris pv. campestris: Role and Regulation of σE-Dependent Activity

The data suggest that RseP and DegS are not only dedicated to RseA cleavage and that the proteolytic cascade of Rse a could involve other proteases, and σ(E) activity is regulated by the putative regulated intramembrane proteolysis (RIP) proteases Rse P and Deg S, as previously described in many other bacteria.
Bordetella pertussis fim3 gene regulation by BvgA: Phosphorylation controls the formation of inactive vs. active transcription complexes

It is suggested that the presence of nonphosphorylated BvgA down-regulates Pfim3 activity when phosphorylatedBvgA is present and may allow the bacterium to quickly adapt to the loss of inducing conditions by rapidly eliminating Pfim 3 activation once the signal for BVGA phosphorylation is removed.
