This result is similar to van der Waals epitaxial growth of MoS2 on graphene [21] and perhaps originates from the higher boundary effect of the Evofosfamide ic50 narrower graphene belt after mechanical exfoliation [25]. Besides, the triangular h-BN nanosheets on graphene showed different in-plane orientations from each other. Raman spectroscopy provided a useful means of gleaning

information about the lattice vibration modes of graphene and h-BN. After being transferred to SiO2/Si by the Scotch tape mechanical exfoliation method, the graphene was generally aligned with the (002) lattice plane parallel to the surface of the SiO2/Si wafer [1, 2]. The existence of graphene was shown by Raman spectra in Figure 3, in which the I 2D/I G ratio of graphene was less than 0.5, indicating the multilayer structure of the graphene. Moreover, a weak D peak of graphene at 1,350 cm-1 was observed from the Raman spectra (Figure 3), indicating a small number of defects in the graphene, which may have originated from the original HOPG or the mechanical exfoliation process. For the sample examined after CVD, a peak much stronger than the D peak of graphene appeared at 1,367 cm-1, indicating the E 2g vibration mode of h-BN, which was consistent with the reported values [5, 6, 13–19]. Interestingly, the 2D and G

peaks for graphene diminished in intensity after CVD, and this may have originated from the partial buy Staurosporine coverage of the graphene by h-BN. As shown in Figure 3b,c, the G peaks of graphene for the graphene substrate and h-BN/graphene were fitted with Lorentz curves (solid lines). The fitting data were well fitted with the raw data, while the Raman frequency and full width at half maximum (FWHMs) for G bands were almost equal to each other. These results are comparable with the reported values of graphene [26] and graphite [27, 28], showing the high quality

of graphene Selleck BIBW2992 before and after CVD and indicating that the synthesis of h-BN nanosheets on graphene in our Phosphatidylinositol diacylglycerol-lyase manuscript does not cause a degradation of graphene. Figure 3 Raman spectra. (a) Raman spectra of graphene before CVD (lower plot) and h-BN/graphene after CVD (upper plot). G peaks fitting with Lorentz curves (solid lines) for graphene substrate (b) and h-BN/graphene (c) are shown with their FWHMs, respectively. According to previous reports [29], the gas-phase nucleation for h-BN was absent at growth temperatures lower than 1,000°C; hence, the growth of h-BN nanosheets on graphene was dominated by the surface nucleation during our CVD process at 900°C. Moreover, the surface topography of the substrate is vital to the surface nucleation [30]. Consequently, the nucleation of the h-BN nanosheets on the graphene substrate was regulated by the surface morphology of graphene in our work.

Due to low abundance, some spots could not be identified unambiguously, revealing a drawback of working with gel-based proteomics. Phase 2 flagellin was downregulated in the luxS mutant, corresponding to what was previously reported by Karavolos et al. [12]. An intriguing observation was the fact that two distinct protein spots, NVP-BSK805 chemical structure absent MEK inhibitor cancer in the luxS mutant as compared to wildtype, were identified by mass spectrometry as being LuxS. This

result led us to investigate the LuxS protein itself in more detail. Figure 1 Image of the master gel used in the 2D-DIGE analysis comparing the proteome of wildtype S. Typhimurium with that of a luxS mutant. Spots with white spot boundaries were differentially expressed. The numbers indicated, correspond to the spot numbers in Table 1.

Efforts to identify the nature of this modification by tandem mass spectrometry were unsuccessful. Phosphorylation

is a common posttranslational modification that induces a protein shift to the acidic side of 2D gels due to the negative charge of the phosphate group. Moreover, LuxS proteins from several Gram-negative bacteria contain a semi-conserved tyrosine phosphorylation site motif [21]. This led us to investigate whether the modification of LuxS in S. Typhimurium corresponds to a tyrosine phosphorylation. First, we attempted to detect a phosphorylated form of LuxS using the phosphospecific ProQ-Diamond stain (Invitrogen) on a 2D gel. However, no LuxS spot could be detected in this way (data not shown). Secondly, Western blotting using anti-phosphotyrosine antibodies was performed on an immunoprecipitated LuxS protein fraction. This immunoprecipitation step increases the LuxS concentration to facilitate detection of a putative phosphorylated form. Yet, LuxS could not be detected by these antibodies, making a tyrosine phosphorylation unlikely (data not shown).

The PCR-DGGE was carried out using a semi-nested NVP-HSP990 order approach, as the bacterial primers targeting the V3-region are known to amplify eukaryotic DNA [52]. Three bands corresponding to these three endosymbionts recurred in all studied M. pygmaeus populations. The DGGE-profile of bacteria in the M. caliginosus populations were similar to those of M. pygmaeus, confirming the presence of Wolbachia and the Rickettsia strain from the ‘Limoniae’ group, but the bellii-like Rickettsia was not found (Fig. 2). A PCR using specific primers for each endosymbiont confirmed this result. The bands with lower density present in some populations corresponded to the Gamma-proteobacteria and Firmicutes. Most of these bands were attributed

to Serratia species of the Enterobacteriaceae family, which have been found in the gut of various insect orders, including Hymenoptera, Lepidoptera, Neuroptera and Hemiptera [53–56]. One band however (Fig. 2, no. 7), has been amplified in five wild Macrolophus populations. This band corresponded to an uncultured Gamma-proteobacterium, the role of which is unknown. The low bacterial diversity in the gut of M. pygmaeus may be attributed to its natural diet. A more diverse bacterial community is mostly detected in insects that consume nutritionally poor diets [57],

AZD9291 cell line whereas the main food of Macrolophus bugs consists of nutrient-rich arthropod prey. Also, the microbial diversity of the investigated Macrolophus spp. may have been underestimated by the dominance of the endosymbionts in its host. Samples of the wild Macrolophus populations were collected in ethanol and DNA-extraction was performed on Ureohydrolase whole adults; gut dissections were thus only AR-13324 feasible for the two laboratory reared populations. The faint bands in the DGGE-profile of the wild populations of Macrolophus may originate from prey remnants in the gut. A PCR-DGGE profile of the gut of the laboratory populations of M. pymaeus and M. caliginosus established the presence of the Gamma-proteobacteria and the Rickettsia endosymbionts in M. pygmaeus (Fig. 3), whereas the gut of M. caliginosus was

only infected by R. limoniae. In both species, Wolbachia was virtually absent in the gastro-intestinal tract. The DGGE profile of the ovaries only indicated an infection by the Wolbachia and Rickettsia endosymbionts, suggesting that no other bacteria infected the reproductive tissues. A diagnostic PCR on adults and ovaries of M. pygmaeus and M. caliginosus confirmed that all individuals are multiple infected and that the endosymbionts are vertically transmitted, implying that the infections are fixed. A FISH analysis confirmed high densities of both Wolbachia and Rickettsia in the ovarioles of M. pygmaeus (Fig. 4 and 5), suggesting a high rate of vertical transmission to the progeny [58]. Wolbachia is the only endosymbiont infecting the studied Macrolophus spp. which is known to cause CI in its insect host [7].

Our study shows a down-regulation of antioxidant enzymes only in the ovaries. This result agrees with those obtained in Drosophila S2 cell line infected by Wolbachia [66] and in A. tabida – Wolbachia symbiosis [24] but not with those from the Ae. albopictus Aa23 cell line IWR1 [22]. In parallel, we show an up-regulation of the thioredoxin gene that could be a response to down-regulation of other genes encoding antioxidant proteins. An alternative hypothesis is that this last gene could be induced by Wolbachia

to reduce apoptosis and accelerate multiplication of gonadic cells. Indeed, in mice, this electron donor protein reduces the process of oxidant molecules but also increases cell proliferation and the inhibition of apoptosis [67]. There was a significant over-expression of Ferritins A and C in symbiotic ovaries. Ferritins are important iron sequestration proteins and play a crucial role in the iron-withholding defence system [68]. The up-regulation of ferritin genes could be an active high throughput screening assay cellular reaction for starving Wolbachia of iron, BGB324 which would lead to bacterial growth limitation. Besides, this over-expression could be the result of the under-expression of the detoxification enzymes (Peroxiredoxin B and C and Glutathione peroxidase). As intracellular free iron produces ROS by the

Fenton reaction in presence of H2O2, iron sequestration could reduce ROS production and thus avoid deleterious effects in the cell. Regardless, this

result contrasts with that obtained in A. tabida-Wolbachia system [24, 69] where the ferritin genes were under-expressed in symbiotic condition. This down-regulation could be due to the dependence phenotype of A. tabida – Wolbachia association for the oocyte maturation, whereas our model is a facultative Wolbachia symbiosis that is not involved in host oogenesis. Autophagy was initially reported as a bulk self-degradation Rho mechanism for the turnover of proteins and organelles. Autophagy can be induced via PGRP-LE, which is essential in the innate bacterial recognition in Drosophila resistance against Listeria monocytogenes [70] suggesting that this biological process is involved in the innate immune response against intracellular bacteria, viruses, and parasites [70, 71]. In our study, the atg7 and atg12 genes involved in autophagy were down-regulated in ovaries. Autophagy-associated genes were down-regulated also in A. tabida-Wolbachia and S. oryzae-SPE symbioses [24, 25], which suggests that this process is critical in bacterial symbiosis. We may hypothesize that this down-regulation was an active strategy of Wolbachia to reduce their elimination by their host. In Wolbachia-infected whole animals, three AMP genes were under-expressed (i.e., armadillidin, crustin 3, and i-type lyzozyme). Armadillidin and crustin are two Gram-positive AMPs [44, 72].

Evaluation of the physical properties of the conidial surface The conidial cell surface electrostatic charge was assessed by microelectrophoresis with a Zetasizer and the cell surface hydrophobiCity (CSH) was assessed by two-phase partitioning with hexadecane as the hydrocarbon phase or using a two-aqueous phase system. Results showed that the electronegative charge of the conidial surface for mutant isolates was much lower than that of the wild-type strains (Table 5). Likewise, two-phase partitioning showed a decrease in CSH for conidia of pigmentless or brownish isolates. This decreased hydrophobiCity

is consistent with the increased wettability observed during the preparation of conidial suspensions. Table 5 Physical properties of the conidial surface Strain or isolate number Zeta potential (mV) Water/hexadecane (%)1 PEG/dextran2 Reference strains          CBS 113.26

Conidia from reference strains CBS 113.26 (A) and IHEM 18963 (B and C) cultivated in the presence (C) or not (A and B) of pyroquilon 20 μg/mL, or of mutant isolates (D and E: pigmentless isolates IHEM 2508 and 9860; F: brownish isolate IHEM 15998) were processed for ultrastructural examination of their cell wall. Note the smooth surface of the conidia of reference strains cultivated in the presence (C) of pyroquilon and mutant isolates (D, E, F) and the lack of the outermost cell wall layer (arrowheads) which sometimes appears free in the surrounding medium (arrows). Bars correspond to 500 nm. Visualisation of the hydrophobic rodlet layer by atomic force microscopy We also investigated the presence of a hydrophobic rodlet layer on the conidial surface, to provide support for our hypothesis. This protein film is usually composed of about 10-nm thick rodlets of varying length organized into bundles or fascicles, in which individual rodlets lie parallel within a single fascicle.
