mBio
. 2024 Sep;
15(10):e0100224.
PMID: 39230277
Importance: Complex communities attached to a surface, or biofilms, represent the major lifestyle of bacteria in the environment. Such a sessile state enables the inhabitants to be more resistant to...

bioRxiv
. 2024 Jan;
PMID: 38168291
Through its cell cycle, the bacterium switches from a motile, free-living state, to a sessile surface-attached cell. During this coordinated process, cells undergo irreversible morphological changes, such as shedding of...

PMID: 36475544
In their natural environment, most bacteria preferentially live as complex surface-attached multicellular colonies called biofilms. Biofilms begin with a few cells adhering to a surface, where they multiply to form...

Microb Genom
. 2017 Nov;
3(9):e000125.
PMID: 29114403
Anoxygenicphotosynthetic prokaryotes have simplified photosystems that represent ancient lineages that predate the more complex oxygen evolving photosystems present in cyanobacteria and chloroplasts. These organisms thrive under illuminated anaerobic photosynthetic conditions,...

Mol Microbiol
. 2013 Oct;
90(6):1277-92.
PMID: 24134691
The purple bacterium Rhodobacter capsulatus is unique among Rhodobacteriacae as it contains a putative iron response regulator (Irr) but does not possess a copy of the ferric uptake regulator (Fur)....

. 2007 Jun;
26(14):3322-31.
PMID: 17581629
Bacteriophytochromes are red/far-red photoreceptors that bacteria use to mediate sensory responses to their light environment. Here, we show that the photosynthetic bacterium Rhodopseudomonas palustris has two distinct types of bacteriophytochrome-related...

PMID: 16009707
Phytochromes are chromoproteins found in plants and bacteria that switch between two photointerconvertible forms via the photoisomerization of their chromophore. These two forms, Pr and Pfr, absorb red and far-red...

279(43):44407-16.
PMID: 15304477
The two closely related bacteria Bradyrhizobium and Rhodopseudomonas palustris show an unusual mechanism of regulation of photosystem formation by light thanks to a bacteriophytochrome that antirepresses the regulator PpsR. In...
