A plane wave source is simulated at normal incidence to the structure. The computational domain (400 nm × 400 nm × 1,000 nm) has a perfectly matched layer (PML), absorbing boundaries in the z direction and periodic boundaries in the x-y plane [36]. A uniform FDTD mesh size is adopted. The mesh size is the same along all Cartesian axes: ∆x = ∆y = ∆z = 2 nm, which is sufficient to minimize the numerical errors arising from the FDTD method. Figure 1 Schematic of the proposed structure. (a) Schematic of the MDM structure consisting of

a 60-nm-thick Bi2Se3 dielectric layer between two 30-nm-thick Au films perforated with a square array of elliptical holes suspended in air. The lattice constant is L = 400 nm, and hole diameters are d 1 = 240 nm and d 2 = 120 nm. (b) Illustration of the square lattice of ENA. The topological

insulator material Bi2Se3 was selected NVP-BGJ398 price due to its significantly different optical properties between the trigonal and orthorhombic phases. The real (ϵ 1) and imaginary (ϵ 2) parts of the dielectric function for the different structural phases of Bi2Se3 were obtained from the published data in [28]; the NIR spectral region is shown in Figure  2. A large change in the dielectric function across the NIR is obtained after switching Bi2Se3 from trigonal to its orthorhombic phase. Figure 2 Dielectric constant of the Bi 2 Se 3 . (a) Real part of dielectric function ϵ 1(ω) for trigonal and orthorhombic phases of Bi2Se3. (b) Imaginary part of dielectric function ϵ 2(ω) for trigonal and orthorhombic all phases of Bi2Se3. After the complex coefficients of selleck transmission and reflection are obtained by the 3D EM Explorer Studio, in which T a is the amplitude and φ a is the phase of the transmission coefficient, and R a is the amplitude and φ ra is the phase of the reflection coefficient, the effective

optical parameters can be extracted using the Fresnel formula [37]. For an equivalent isotropic homogenous slab of thickness h surrounded by semi-infinite media with refractive index n 1 and n 3 under normal incidence, we have (1) (2) The so-called material parameters ϵ eff and μ eff of a single layer of a double-fishnet negative-index metamaterial are extracted using the well-known Nicholson-Ross-Weir (NRW) method [38–40]. Therefore, once n eff and η are evaluated, the effective permittivity and permeability are calculated using (3) where n eff is the effective refractive index, η is the impedance, h is the thickness of the structure, k = ω/c, c is the speed of light, m is an arbitrary integer, and n 1 = n 3 = 1 since the structure is suspended in a vacuum. The signs of n eff and η and the value of m are resolved by the passivity of the metamaterial that requires the signs of the real part of impedance η and imaginary part of effective index n eff to be positive, i.e., Real(η) > 0, Imag(n eff) > 0 which is consistent with the study described in [39, 40].

Overall the observed induction of exo genes is in agreement with

Overall the observed induction of exo genes is in agreement with the mucoid phenotype observed for S. meliloti after growing on low pH plates (data not shown). In low pH soils this response could be a strategy of the cell to establish a more VX-680 manufacturer favourable microenvironment by secreting succinoglycan. It was shown that an EPS I overproduction results in a reduced nodulation efficiency [54], therefore PRI-724 molecular weight the induction of EPS I biosynthesis genes could also be one of the reasons for the observed limited nodulation efficiency of rhizobia in low pH soils [2]. Figure 4 Map of genes in the EPS I biosynthesis region on pSymB and their expression in response

to acidic pH. The EPS I biosynthesis gene region on pSymB is schematically displayed with its genes given by open arrows coloured according to the K-means cluster distribution. Gene names are given below. Black arrows indicate known operon structures in this region. The graph above shows on the Y-axis the time after pH-shift and on the Z-axis for each time point the expression of the corresponding genes by the M value. Whereas the exo gene expression was increased, several MRT67307 supplier genes of chemotaxis and flagellar biosynthesis (flgB, flgG, flgL, flgF, flgC, flgE, fliE, flbT, motA, mcpU) were decreased in their expression levels. After 63 minutes of low pH treatment

the genes have reached the highest level of repression. VisR is the main activator of the flagellar genes and forms together with VisN the top layer of a hierarchy of three expression classes. Since the visN gene expression was decreased early in the time course experiment (therefore visN was grouped into cluster E) the other flagellar genes follow the repression of their activator [55]. The gene coding for the subordinated regulator Rem [56] was also decreasingly expressed with time, but did not reach the threshold for clustering. A detailed

consideration of the expression levels of the flagellar biosynthesis genes on the chromosome (Fig. 5) reveals a repression of the complete region, with some parts responding stronger than others. The decreased expression level of motA, flgF and flgE is likely to be a result of their first position in an operon. It is noticeable that among the 10 down-regulated and strongly responding SPTBN5 flagellar genes in cluster F five are coding for parts of the rod (flgF, flgB, flgC, fliE and flgG) and two for parts of the hook (flgE and flgL) of the flagellum. The genes motA, fliM, fliN and fliG are proposed to form an operon [55]. While the expression of motA, which is coding for a transmembrane proton channel protein, was decreased in the time course experiment, the other three genes which encode flagellar switch proteins did not respond to the shift to acidic pH. If this behaviour is caused by a specific regulation or is due to mRNA degradation processes cannot be answered.

3, indicative of negative or purifying selection operating on these orthologs. A one-way ANOVA demonstrated that the distributions of ω among the four R. sphaeroides strains were

not significantly different from one another (p = 0.920). For the four strains, the mean ω value varied between 0.131 and 0.137 and the standard deviation of ω varied LY2606368 mw between 0.030 and 0.037 (pooled S.D. = 0.033). Figure 10 K a -K s correlation of 28 common gene pairs in four R. sphaeroides strains (2.4.1, ATCC 17025, ATCC 17029, and KD131). Ka and Ks values were estimated using MYN (Modified Yang-Nielsen algorithm). ω = 0.3, 1, and 3 were used for negative, neutral, and positive selection, respectively. Horizontal Gene Transfer For R. sphaeroides 2.4.1, the putative HGT I-BET151 manufacturer regions were found both in CI and CII. The non-optimized coordinates for these regions are not shown. The CI HGT regions sum to 65,005 nucleotides, which spans over 60 genes and which ZD1839 mw comprises 2.04% of the total CI replicon. The CII HGT regions sum to 110,009 nucleotides,

containing 99 genes, and comprises 11.66% of the total CII replicon. Of the 60 HT genes in CI, 5 are among the duplicate gene pairs, while of the 99 HT genes in CII, 8 are among the duplicate gene pairs. The distribution of HGT regions on both chromosomes revealed that most of the duplicated genes are outside of these HGT regions. Discussion Extent of gene duplication and horizontal gene transfer in R.

sphaeroides A systematic genome analysis of the R. sphaeroides, which possess multiple chromosomes, has shown approximately the same level of gene duplication (~28%) as reported in many other bacterial genomes that possess only one chromosome [22, 42–44] and eukaryotes [22, 45–47]. Thus, similar levels of gene AZD9291 price duplication in the genomes of eubacteria, archeae, and eukarya suggest that genome size or genome complexity and the levels of gene duplication present in their genomes are not correlated. Gene duplication can occur on two different scales: large-scale duplication (whole-genome duplication, WGD) and smaller-scale duplications, which consists of tandem duplication of short DNA sequence within a gene, duplication of the entire gene or duplication of large genomic segments [48–50]. The majority of gene duplications in R. sphaeroides exist in the form of small DNA segments (one or few genes), but a few duplications span over a large segment of genomic segments. For example, chemotaxis-related genes are located at four major loci, chemotaxis operon I (RSP2432-RSP2444), chemotaxis operon II (RSP1582-RSP1589), chemotaxis operon III (RSP0042-RSP0049), and chemotaxis operon IV is a part of a 56 kb- flagella biosynthesis gene cluster (RSP0032-RSP0088). Three copies are present on CI and one copy is present on CII.

Initially, specific shapes (triangle or hexagonal) were obtained

Initially, specific shapes (triangle or hexagonal) were obtained when lower DMAB molar (0.066 or 0.16 mM, respectively) was added (Figure 7a,b). However, these shapes and the resultant color dramatically changed (brown or orange color) when higher DMAB molar (0.66 and 3.33 mM) was added to the solution. The final position of their maximum absorption bands (UV–vis spectroscopy) was at 410 nm, and the resultant FGFR inhibitor orange color indicates the excitation of the LSPR of selleck inhibitor spherical shapes (Figure 7d). Figure 7 TEM micrographs that show the formation of

AgNP with different shapes for different DMAB concentrations. (a) Triangle shape with 0.066 mM DMAB. (b) Hexagonal shape with 0.16 mM DMAB. (c) Quasi-spherical shape with 0.66 mM DMAB. (d) Spherical shape with 3.33 mM DMAB. The PAA concentration was 25 mM. Finally, an important aspect observed in this study is the evolution of having the same shapes (rod,

triangle, hexagonal, Microbiology inhibitor and spherical) for different PAA concentrations when DMAB molar was gradually increased. Figure 8 shows a similar evolution in the resulting shapes as a function of DMAB molar added in the presence of 10 mM PAA. Initially, rod or triangle shapes were observed for lower DMAB molar (0.033 and 0.066 mM), but a change in the shape to hexagonal or spherical were observed when DMAB molar was increased (0.66 or 6.66 mM, respectively). In addition, UV–vis spectroscopy (not shown here) revealed identical spectral changes

in the maximum absorption band in both regions. Firstly, an absorption band is obtained in region 2 that PDK4 corresponds to rod, triangle, or hexagonal shapes (Figure 8a,b,c, respectively), and secondly, this absorption band was displaced to shorter wavelengths in region 1, appearing as an intense absorption band at 410 nm due to the synthesis of spherical nanoparticles (Figure 8d). Figure 8 TEM micrographs showing the formation of AgNP using 10 mM PAA and different DMAB concentrations. (a) Rod shape with 0.033 mM DMAB. (b) Triangle shape with 0.066 mM DMAB. (c) Hexagonal shape with 0.66 mM DMAB. (d) Spherical shape with 6.66 mM DMAB. Other considerations A relevant aspect of this work is the synthesis of silver reddish nanoparticles in the presence of 2.5 mM PAA because this color is not obtained with lower or higher PAA concentrations. In Figure 9 (left), it is possible to appreciate the evolution of the maximum absorption band (UV–vis spectroscopy) when variable DMAB molar is added to the solution. It is worth noting that the intensity of the peak corresponding to the red solution is broader than in the yellow or orange solution, indicating a considerable increase and aggregation in the number of synthesized silver nanoparticles.

“Background Debaryomyces hansenii is an ascomycetous salt- and high pH-tolerant yeast that has been defined as halotolerant or halophilic [1]. It was isolated from saline environments such as sea water [2] or concentrated brines [3], representing one of the most salt tolerant species of yeasts. This marine yeast can Semaxanib tolerate salinity levels up to 24% (4.11 M) of NaCl [2]. In contrast, growth of the Baker’s yeast Saccharomyces cerevisiae is severely Mizoribine clinical trial inhibited when salinity reaches 10% NaCl [3]. Thus, D. hansenii has become a model organism for the study of salt tolerance mechanisms in eukaryotic cells [4]. It is now well recognized that the mechanisms by which all organisms achieve osmotic and ionic equilibrium are mediated by orthologous

NVP-BEZ235 mechanisms based on conserved biochemical and/or physiological functions that are inherently necessary for essential metabolic processes [5]. Under saline conditions, D. hansenii accumulates large amounts of Na+ without being intoxicated even when K+ is present at low concentration in the environment [6]. In fact, Na+ improves growth and protects D. hansenii in the presence

of additional stress factors [1]. For example, at high or low temperature and extreme pH growth of the yeast Bay 11-7085 is improved by the presence of 1 M NaCl [7]. It has been clearly shown that sodium ions are less toxic for D. hansenii as compared with other organisms; therefore, it is considered a ‘sodium-includer’ organism [8]. The reduced toxic effect by Na+ and its accumulation at high levels under high salt is probably indicative of an adaptive strategy of D. hansenii for growth in hypersaline environments [9]. The organism must posses an array of advantageous characteristics that collectively confer its high halotolerance. Earlier studies have identified a number of salt-related genes in the extreme halophilic yeast D. hansenii, such as HOG1 (MAP kinase involved in high-osmolarity glycerol synthesis pathway) [10], ENA1 and ENA2 (plasmamembrane Na+-ATPase [11], GPD1 and GPP (NAD-glycerol-3-phosphate dehydrogenase and glycerol-3-phosphatase) [12], NHX1 (vacuolar Na+ antiporter) [13] and KHA1 (Na+/H+ antiporter) [14]. As expected, most of these salt-upregulated genes are involved in osmoregulation or transport of ions. However, the collective underlying mechanisms by which D. hansenii tolerates high levels of NaCl remain unkown. All aerobic organisms require oxygen for efficient production of energy, but at the same time the organisms are constantly exposed to oxidative stress. This can be caused by partially reduced forms of molecular oxygen (e.g.
