Histone deacetylases (HDACs) play a key role in regulating plant growth, development and stress responses. However, functions of HDACs in woody plants are largely unknown. In this study, a novel gene encoding a RPD3/HDA1-type histone deacetylase was cloned from 84K poplar (Populus alba×Populus glandulosa) and designated as 84KHDA903. The 84KHDA903 encodes a protein composed of 500 amino acid residues, which contains a conserved HDAC domain. Transient expression of 84KHDA903 in onion epidermal cells suggested that it was exclusively localized in nucleus...

In this Letter, the use of two-coupled Mach-Zehnder interferometers for four π/2-phase shifting interferometry is introduced. A multi-camera arrangement using no more than beam splitters and mirrors is utilized to obtain in a single shot the needed phase-shifted interferograms in the different output channels of the setup. The simplicity of the setup makes it ideal for high-speed interferometry applications. This proposal is validated in digital holographic microscopy to visualize a biological sample of epidermal onion cells...

Emulsification-induced assembly is employed to allow structural diversity in nanoaggregates of a biocompatible amphiphilic polymer, poly(ethylene oxide)-block-poly(ε-caprolactone). Onion-like vesicles are efficiently produced by tuning the interfacial instability of the oil-in-water emulsion. The increase in the polymer concentration and use of the organic solvents with a low interfacial tension between water and the oil phase lead to a strong tendency of emulsion droplets to generate the onion-like vesicles...

Inspired by the experimentally synthesized Na12@[(UO2)(O2)1.5]208- ("Na12@U20") cluster, we have explored computationally the substitution of the Na cations by many other metals. 6 other M12@U20 systems are found to be stable (M = K+, Rb+, Cs+, Ag+, Mg2+, Fe2+). For 3 of these (Mg2+, Ag+ and Na+), the cluster can supporta group 16 dianion at its centre, forming a new type of Matryoshka ("Russian Doll") actinide nanocluster E@M12@U20 (E = S2-, Se2-, Te2- and Po2-). These systems have 3 shell, onion like geometries with nearly perfect Ih symmetry...

Carbon nanomaterials (CNMs) are increasingly employed in nanomedicine as carriers for intracellular transport of drugs, imaging probes, and therapeutics agents, thanks to their unique optical and physicochemical properties. However, a better understanding about the effects of CNMs on a vertebrate model at the whole animal level is required. In this study, we compare the toxicity of oxidized carbon nano-onions (oxi-CNOs), oxidized carbon nano-horns (oxi-CNHs) and graphene oxide (GO) in zebrafish (Danio rerio)...

Xyloglucan has been hypothesized to bind extensively to cellulose microfibril surfaces and to tether microfibrils into a load-bearing network, thereby playing a central role in wall mechanics and growth, but this view is challenged by newer results. Here we combined high-resolution imaging by Field-Emission Scanning Electron Microscopy (FESEM) with nanogold affinity tags and selective endoglucanase treatments to assess the spatial location and conformation of xyloglucan in onion cell walls. FESEM imaging of xyloglucanase-digested cell walls revealed an altered microfibril organization but did not yield clear evidence of xyloglucan conformations...

The onion maggot, Delia antiqua, is a worldwide subterranean pest and can enter diapause during summer and winter seasons. The molecular regulation of the ontogenesis transition remains largely unknown. Here we used high-throughput RNA-Seq to identify candidate genes and processes linked to summer diapause induction by comparing the transcriptome differences between the most sensitive larval developmental stage of summer-diapause (SD) and non-diapause (ND). Nine pair-wise comparisons were performed and significantly differentially regulated transcripts were identified...

Semiconductors with native ferromagnetism barely exist and defined nanostructures are almost unknown. This lack impedes the exploration of a new class of materials characterized by a direct combination of effects on the electronic system caused by quantum confinement effects with magnetism. A good example is EuO for which currently no reliable routes for nanoparticle synthesis can be established. Bottom-up approaches applicable to other oxides fail because of the labile oxidation state +II. Instead of targeting a direct synthesis, the two steps-"structure control" and "chemical transformation"-are separated...

Chloroform and Bromoform are two abundant trihalomethanes found in Algerian drinking water. The investigation of the mutagenic hazard of these disinfection by-products was studied by Ames test as prokaryotic bioassay to show their mutagenic effects. For this, Salmonella typhimurium TA98 and TA100 strains were employed. Both chloroform and bromoform showed a direct mutagenic effect since the number of revertant colonies gradually increase in dose-dependent manner with all concentrations tested with the two bacterial strains and these were both in the absence and presence of S9 metabolic activation...
