Genomics of Clinal Local Adaptation in Pinus sylvestris Under Continuous Environmental and Spatial Genetic Setting

open access: yesG3: Genes, Genomes, Genetics, 2020
Understanding the consequences of local adaptation at the genomic diversity is a central goal in evolutionary genetics of natural populations. In species with large continuous geographical distributions the phenotypic signal of local adaptation is ...

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Numerical treatment of seismic accelerograms and of inelastic seismic structural responses using harmonic wavelets [PDF]

open access: yes, 2007
The harmonic wavelet transform is employed to analyze various kinds of nonstationary signals common in aseismic design. The effectiveness of the harmonic wavelets for capturing the temporal evolution of the frequency content of strong ground motions is ...

Large-Scale Structural Variation Detection in Subterranean Clover Subtypes Using Optical Mapping

open access: yesFrontiers in Plant Science, 2018
We selected two genetically diverse subspecies of the Trifolium model species, subterranean clover cvs. Daliak and Yarloop. The structural variations (SVs) discovered by Bionano optical mapping (BOM) were validated using Illumina short reads.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

open access: yesFEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Genetic variation affecting exon skipping contributes to brain structural atrophy in Alzheimer's disease [PDF]

open access: yes, 2018
Genetic variation in cis-regulatory elements related to splicing machinery and splicing regulatory elements (SREs) results in exon skipping and undesired protein products.

Investigating structural variant, indel and single nucleotide polymorphism differentiation between locally adapted Atlantic salmon populations

open access: yesEvolutionary Applications
Genomic structural variants (SVs) are now recognized as an integral component of intraspecific polymorphism and are known to contribute to evolutionary processes in various organisms.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

open access: yesFEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Anatomical characteristics of leaves from Teak (Tectona grandis L.f.)

open access: yesEvidência, 2009
The in vitro culture promotes changes anatomical, physiological and morphological in plants. The objective of this work was to compare the structural characteristics of leaves of Tectona grandis in in vitro culture and ex vitro.

STRUCTURAL VARIATIONS IN PEAT [PDF]

open access: yesNew Phytologist, 1969
SummaryThe macro‐ and microscopic structure of an upland bog in north‐east Scotland was examined at two sites, where four main horizons were recognized according to dominant botanical constituents, degree of decomposition and texture after weathering. The botanical composition varied most markedly in the first and second horizons, decomposition in the ...
