Increased variability of microbial communities in restored salt marshes nearly 30 years after tidal flow restoration [PDF]

, 2012
We analyzed microbial diversity and community composition from four salt marsh sites that were impounded for 40–50 years and subsequently restored and four unimpounded sites in southeastern Connecticut over one growing season.

Diversity and biosynthetic potential of culturable microbes associated with toxic marine animals [PDF]

, 2013
Tetrodotoxin (TTX) is a neurotoxin that has been reported from taxonomically diverse organisms across 14 different phyla. The biogenic origin of tetrodotoxin is still disputed, however, TTX biosynthesis by host-associated bacteria has been reported.

Time series genome-centric analysis unveils bacterial response to operational disturbance in activated sludge [PDF]

, 2019
Understanding ecosystem response to disturbances and identifying the most critical traits for the maintenance of ecosystem functioning are important goals for microbial community ecology.

Taxonomic Resolutions Based on 18S rRNA Genes: A Case Study of Subclass Copepoda

PLoS ONE, 2015
Biodiversity studies are commonly conducted using 18S rRNA genes. In this study, we compared the inter-species divergence of variable regions (V1–9) within the copepod 18S rRNA gene, and tested their taxonomic resolutions at different taxonomic levels ...

Unbalanced rRNA gene dosage and its effects on rRNA and ribosomal-protein synthesis [PDF]

Journal of Bacteriology, 1985
The synthesis of rRNA was unbalanced by the introduction of plasmids containing rRNA operons with large internal deletions. Significant unbalanced synthesis was achieved only when the deletions affected both 16S and 23S RNA genes or when the deletions affected the 23S RNA gene alone.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Characterisation of dairy strains of Geobacillus stearothermophilus and a genomics insight into its growth and survival during dairy manufacture : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Microbiology at Massey University, Palmerston North, New Zealand [PDF]

, 2016
The thermophilic bacilli, such as G. stearothermophilus, are an important group of contaminants in the dairy industry. Although these bacilli are generally not pathogenic, their presence in dairy products is an indicator of poor hygiene and high numbers ...

Complete genome sequence of Meiothermus silvanus type strain (VI-R2). [PDF]

, 2010
Meiothermus silvanus (Tenreiro et al. 1995) Nobre et al. 1996 belongs to a thermophilic genus whose members share relatively low degrees of 16S rRNA gene sequence similarity.

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Variable rRNA gene copies in extreme halobacteria

Nucleic Acids Research, 1988
Using PFG electrophoresis techniques, we have examined the organization of rRNA gene in halobacterium species. The results show that the organization of rRNA genes among closely related halobacteria is quite heterogeneous. This contrasts with the high degree of conservation of rRNA sequence (1).
