The importance of detailed epigenomic profiling of different cell types within organs. [PDF]

, 2016
The human body consists of hundreds of kinds of cells specified from a single genome overlaid with cell type-specific epigenetic information. Comprehensively profiling the body's distinct epigenetic landscapes will allow researchers to verify cell types ...

The Role of Methylation of DNA in Environmental Adaptation [PDF]

Integrative and Comparative Biology, 2013
Methylation of DNA is an epigenetic mechanism that influences patterns of gene expression. DNA methylation marks contribute to adaptive phenotypic variation but are erased during development. The role of DNA methylation in adaptive evolution is therefore unclear.

The complete mitochondrial genome of the Mekong Giant Salmon Carp (Aaptosyax grypus): a tool to conserve an emblematic and elusive megafish

Knowledge and Management of Aquatic Ecosystems
The giant salmon carp is a Critically Endangered megafish from the Mekong River. Despite its emblematic species status, it is rarely observed, and less than 30 confirmed specimens have been recorded since the original species description in 1991.

Persistence of Environmental DNA in Freshwater Ecosystems

PLoS ONE, 2011
The precise knowledge of species distribution is a key step in conservation biology. However, species detection can be extremely difficult in many environments, specific life stages and in populations at very low density. The aim of this study was to improve the knowledge on DNA persistence in water in order to confirm the presence of the focus species

Blinking statistics of a molecular beacon triggered by end-denaturation of DNA

, 2005
We use a master equation approach based on the Poland-Scheraga free energy for DNA denaturation to investigate the (un)zipping dynamics of a denaturation wedge in a stretch of DNA, that is clamped at one end.

Self-reported pregnancy exposures and placental DNA methylation in the MARBLES prospective autism sibling study. [PDF]

, 2016
Human placenta is a fetal-derived tissue that offers a unique sample of epigenetic and environmental exposures present in utero. In the MARBLES prospective pregnancy study of high-risk younger siblings of children with autism spectrum disorder (ASD ...

Preliminary survey of Aphanomyces sp. associated with native and invasive crayfish in the Lower Susquehanna watershed of South Central Pennsylvania

Journal of Freshwater Ecology, 2020
The oomycete species, Aphanomyces astaci, is well known as the devastating causal agent of European crayfish plague. Despite assumptions of a North American origin, the prevalence and distribution of A. astaci in its presumed native range is unknown.

Mitogenomic Insights into Orthocladiinae (Diptera: Chironomidae): Structural Diversity and Phylogenetic Implications

Biology
Mitochondrial genomes are powerful tools for taxonomic delimitation and species identification, yet they remain scarce for Chironomidae (Diptera). In this study, we assembled and annotated 63 new mitochondrial genomes, encompassing 63 species within 39 ...

Candida albicans repetitive elements display epigenetic diversity and plasticity [PDF]

, 2016
Transcriptionally silent heterochromatin is associated with repetitive DNA. It is poorly understood whether and how heterochromatin differs between different organisms and whether its structure can be remodelled in response to environmental signals. Here,

Analysis of environmental transcriptomes by DNA microarrays

Environmental Microbiology, 2006
SummaryIn this work we investigated the correlations between global gene expression patterns and environmental parameters in natural ecosystems. We studied the preferential gene expression of the iron oxidizer bacterium Leptospirillum ferrooxidans to adapt its physiology to changes in the physicochemical parameters in its natural medium.
