Intergeneric and interspecific relationships in tribe Ricineae revealed by phylogenomics of the plastome and transcriptome.

Introduction: The taxonomy of Euphorbiaceae is extremely difficult, especially the phylogeny of closely related genera. In , which embraces an important non-food oil-seed crop worldwide, and are closely related genera based on molecular evidence (tribe Ricineae), however the intergeneric and interspecific relationship of the tribe is not well-resolved.

Methods: Plastome and transcriptome were sequenced and assembled before maximum likelihood and Bayesian inference phylogenetic trees were reconstructed.

Incorporating genetic load contributes to predicting Arabidopsis thaliana's response to climate change.

Understanding how species respond to climate change can facilitate species conservation and crop breeding. Current prediction frameworks about population vulnerability focused on predicting range shifts or local adaptation but ignored genetic load, which is also crucial for adaptation. By analyzing 1115 globally distributed Arabidopsis thaliana natural accessions, we find that effective population size (N) is the major contributor of genetic load variation, both along genome and among populations, and can explain 74-94% genetic load variation in natural populations.

Identification of Serum Oxylipins Associated with the Development of Coronary Artery Disease: A Nested Case-Control Study.

Coronary artery disease (CAD) is among the leading causes of death globally. The American Heart Association recommends that people should consume more PUFA-rich plant foods to replace SFA-rich ones to lower serum cholesterol and prevent CAD. However, PUFA may be susceptible to oxidation and generate oxidized products such as oxylipins.

Protective Effect of Cordycepin on Impairment of Endothelial Function in Type 2 Diabetes Mellitus.

Type 2 diabetes mellitus (T2DM) is a major risk factor for cardiovascular diseases. The reduction of mitochondrial protein sirtuin protein 3 (SIRT3) has been reported to contribute to the development of T2DM by impacting mitochondrial respiration. Cordycepin is an adenosine derivative and is isolated from the culture filtrate of Cordyceps militaris.

Self-Assembly Anisotropic Magnetic Nanowire Films Induced by External Magnetic Field.

Self-assembly generated materials induced by an external magnetic field have attracted considerable interest following the development of nanodevices. However, the fabrication of macroscopic and anisotropic magnetic films at the nanoscale remains a challenge. Here, anisotropic magnetic films are successfully prepared using a solution-based nanowire assembly strategy under a magnetic field.

Temperature-Invariant Superelastic and Fatigue Resistant Carbon Nanofiber Aerogels.

Superelastic and fatigue-resistant materials that can work over a wide temperature range are highly desired for diverse applications. A morphology-retained and scalable carbonization method is reported to thermally convert a structural biological material (i.e.

Transposable elements drive rapid phenotypic variation in .

Rapid phenotypic changes in traits of adaptive significance are crucial for organisms to thrive in changing environments. How such phenotypic variation is achieved rapidly, despite limited genetic variation in species that experience a genetic bottleneck is unknown. , an annual and inbreeding forb (Brassicaceae), is a great system for studying this basic question.

Transposable Elements Contribute to the Adaptation of Arabidopsis thaliana.

Transposable elements (TEs) are mobile genetic elements with very high mutation rates that play important roles in shaping genome architecture and regulating phenotypic variation. However, the extent to which TEs influence the adaptation of organisms in their natural habitats is largely unknown. Here, we scanned 201 representative resequenced genomes from the model plant Arabidopsis thaliana and identified 2,311 polymorphic TEs from noncentromeric regions.

Ultrathin Tungsten Oxide Nanowires/Reduced Graphene Oxide Composites for Toluene Sensing.

Graphene-based composites have gained great attention in the field of gas sensor fabrication due to their higher surface area with additional functional groups. Decorating one-dimensional (1D) semiconductor nanomaterials on graphene also show potential benefits in gas sensing applications. Here we demonstrate the one-pot and low cost synthesis of WO NWs/rGO composites with different amount of reduced graphene oxide (rGO) which show excellent gas-sensing properties towards toluene and strong dependence on their chemical composition.

Photothermal poly(N-isopropylacrylamide)/Fe3O4 nanocomposite hydrogel as a movable position heating source under remote control.

Multifunctional nanocomposite hydrogel: swelling-shrink transition of the magnetic sensitive poly(N-isopropylacrylamide)/Fe3O4 (PNIPAM/Fe3O4) nanocomposite hydrogel can be controlled via near-infrared (NIR) laser exposure or non-exposure, which shows potential as a movable position heating source manipulated by combination of an external magnet and near-infrared laser irradiation.

Carbon nanofiber aerogels for emergent cleanup of oil spillage and chemical leakage under harsh conditions.

To address oil spillage and chemical leakage accidents, the development of efficient sorbent materials is of global importance for environment and water source protection. Here we report on a new type of carbon nanofiber (CNF) aerogels as efficient sorbents for oil uptake with high sorption capacity and excellent recyclability. Importantly, the oil uptake ability of the CNF aerogels can be maintained over a wide temperature range, from liquid nitrogen temperature up to ca.

Selective synthesis of Zn(1 - x)Mn(x)Se nanobelts and nanotubes from [Zn(1 - x)Mn(x)Se](DETA)0.5 nanbelts in solution (x = 0-0.15) and their EPR and optical properties.

Zn(1 - x)Mn(x)Se (x = 0-0.15) nanobelts and nanotubes can be synthesized via the removal of diethylenetriamine (DETA) in 1-octadecene (ODE) and ethylene glycol (EG), respectively, using [Zn(1 - x)Mn(x)Se](DETA)(0.5) nanobelts as a template.
