Revision and expansion of the genus Spirirestis (Tolypothrichaceae, Cyanobacteria)
Abstract Recent phylogenetic analyses of members of the Tolypothrichaceae (Nostocales, Cyanobacteria) based on 16S rRNA gene sequence data have demonstrated that the soil‐inhabiting members of the family belong to a clade separate from the aquatic and subaerial members of the family.

Galactose Metabolism Plays a Crucial Role in Biofilm Formation by Bacillus subtilis [PDF]
Galactose is a common monosaccharide that can be utilized by all living organisms via the activities of three main enzymes that make up the Leloir pathway: GalK, GalT, and GalE.

COL is an unusual “model” strain of Staphylococcus aureus that exhibits slow growth and multidrug antibiotic tolerance. This phenotype is primarily due to a mutation in Prs, which synthesizes the core metabolite phosphoribosyl pyrophosphate (PRPP). Introduction of the COL Prs allele into the antibiotic‐susceptible strain Newman confers tolerance, while

Regulatory activity revealed by dynamic correlations in gene expression noise [PDF]
Gene regulatory interactions are context dependent, active in some cellular states but not in others. Stochastic fluctuations, or 'noise', in gene expression propagate through active, but not inactive, regulatory links^(1,2).

DASH: a versatile and high‐capacity gene stacking system for plant synthetic biology
Summary DNA assembly systems based on the Golden Gate method are popular in synthetic biology but have several limitations: small insert size, incompatibility with other cloning platforms, DNA domestication requirement, generation of fusion scars, and lack of post‐assembly modification.

Molecular Distributions in Gene Regulatory Dynamics [PDF]
We show how one may analytically compute the stationary density of the distribution of molecular constituents in populations of cells in the presence of noise arising from either bursting transcription or translation, or noise in degradation rates ...

ABSTRACT Rhizorhabdus wittichii RW1 is known for its ability to degrade polycyclic aromatic hydrocarbons, such as dibenzo‐p‐dioxin (DD) and dibenzofuran (DF). We hypothesized that the R. wittichii RW1 benzoate 1,2‐dioxygenase shares electron transfer components with the DD/DF angular dioxygenase (DxnA1A2), similar to many aromatic hydrocarbon degrading

Unraveling the molecular basis of subunit specificity in P pilus assembly by mass spectrometry [PDF]
P pili are multisubunit fibers essential for the attachment of uropathogenic Escherichia coli to the kidney. These fibers are formed by the noncovalent assembly of six different homologous subunit types in an array that is strictly defined in terms of ...

A novel TetR‐like regulator (EppR) has been identified to repress genes encoding DNA polymerase V in Acinetobacter baumannii through the direct binding of a conserved EppR motif in their promoters. EppR works with previously identified regulator UmuDAb to serve as co‐regulators of these genes. In response to DNA damage and/or environmental stress, both

We show that a sucrose gene cluster enhances the fitness and pathogenicity of Pseudomonas syringae pv. aesculi on horse chestnut, highlighting sucrose metabolism as important for tree colonisation. ABSTRACT Pseudomonas syringae pathovar aesculi (E‐Pae) causes bleeding canker disease in the woody tissue of European horse chestnut (HC).
