Programmed heterogeneity: Epigenetic mechanisms in bacteria
(Elsevier, 2013)
Contrary to the traditional view that bacterial populations are clonal, single-cell analysis reveals that phenotypic heterogeneity is common in bacteria. Formation of distinct bacterial lineages appears to be frequent ...

The Prefoldin Complex Regulates Chromatin Dynamics during Transcription Elongation
(Public Library of Science, 2013)
Transcriptional elongation requires the concerted action of several factors that allow RNA polymerase II to advance through chromatin in a highly processive manner. In order to identify novel elongation factors, we performed ...

The role of flagella and chemotaxis genes in host pathogen interaction of the host adapted Salmonella enterica serovar Dublin compared to the broad host range serovar S. Typhimurium
(BioMed Central, 2013)
Background The importance of flagella and chemotaxis genes in host pathogen interaction in Salmonella enterica is mainly based on studies of the broad host range serovar, S. Typhimurium, while little is known on the ...

The oxygenase CAO-1 of Neurospora crassa is a resveratrol cleavage enzyme.
(American Society for Microbiology, 2013)
The genome of the ascomycete Neurospora crassa encodes CAO-1 and CAO-2, two members of the carotenoid cleavage oxygenase family that target double bonds in different substrates. Previous studies demonstrated the role of ...

DsbA and MgrB regulate steA expression through the two-component system PhoQ/PhoP in Salmonella enterica.
(American Society for Microbiology, 2013)
SteA is a protein that can be translocated into host cells through the two virulence-related type III secretion systems that are present in Salmonella enterica. We used the T-POP system to carry out general screens for ...

Cell-Type–Specific Transcriptional Profiles of the Dimorphic Pathogen Penicillium marneffei Reflect Distinct Reproductive, Morphological, and Environmental Demands
(Genetics Society of America:, 2013)
Penicillium marneffei is an opportunistic human pathogen endemic to Southeast Asia. At 25° P. marneffei grows in a filamentous hyphal form and can undergo asexual development (conidiation) to produce spores (conidia), the ...

Light-dependent functions of the Fusarium fujikuroi CryD DASH cryptochrome in development and secondary metabolism
(American Society for Microbiology, 2013)
DASH (Drosophila, Arabidopsis, Synechocystis, human) cryptochromes (cry-DASHs) constitute a subgroup of the photolyase cryptochrome family with diverse light-sensing roles, found in most taxonomical groups. The genome of ...
