Project description:We characterized and compared hemolymph proteome of Royal Jelly bees (RJbs), a stock selected for increasing RJ output from Italian bees (ITbs) and ITbs across the larval and adult ages. Unprecedented depth of proteome was attained by identifying 3394 hemolymph proteins in both bee lines. The proteome supports the general function of hemolymph to drive development and immunity across different phases in both bees. However, age-specific proteome settings have adapted to prime the distinct physiology for larvae and adult bees. In larvae, proteome are thought to drive the temporal immunity, rapid organogenesis, and reorganization of larval structures. In adults, proteome play key roles to prompt tissues development and immune defense in NEBs, glands maturity in NBs and carbohydrate energy production in FBs. Comparing the proteome between the same aged larval and adult samples, RJbs and ITbs have tailored distinct hemolymph proteome programs to drive their physiology. Particularly, in day 4 larvae and NBs, a large number of highly abundant proteins enriched in protein synthesis and energy metabolism in RJbs relative to ITbs imply that RJb larvae and NBs have reprogrammed their proteome to initiate different developmental trajectory and high RJ secretion in response to the enhanced RJ production by selection. Our hitherto depth of proteome coverage gains novel sight on molecular details in driving hemolymph function and high RJ production by RJbs.

Project description:The innate immune response of insects relies on several humoral and cellular mechanisms that require the activation of circulating proteases in the hemolymph to be functional. Here, we analyzed the gelatinase and caseinase activities of Drosophila larval hemolymph under normal and pathogenic conditions (bacterial lipopolysaccharides or endoparasitoid Leptopilina boulardi) using in gel zymography. Gelatinase activity was more intense than caseinase activity and qualitative and quantitative variations were observed between D. melanogaster strains and Drosophila species. Mass spectrometry identified a large number of serine proteases in gel bands equivalent to the major gelatinase and caseinase bands and of these, the most abundant and redundant were Tequila and members of the Jonah and Trypsin protease families. However, hemolymph from Tequila null mutant larvae showed no obvious changes in zymographic bands. Nor did we observe any significant changes in hemolymph gelatinases activity 24 h after injection of bacterial lipopolysaccharides or after oviposition by endoparasitoid wasps. These data confirmed that many serine proteases are present in Drosophila larval hemolymph but those with gelatinase and caseinase activity may not change drastically during the immune response.

Project description:This study assessed the development of disseminated candidiasis within Galleria mellonella larvae and characterised the proteomic responses of Candida albicans to larval hemolymph. Infection of larvae with an inoculum of 1 × 106 yeast cell reduced larval viability 24 (53.33 ± 3.33%), 48 (33.33 ± 3.33%) and 72 (6.66 ± 3.33%) hour post infection. C. albicans infection quickly disseminated from the site of inoculation and the presence of yeast and hyphal forms were found in nodules extracted from infected larvae at 6 and 24 hours. A range of proteins secreted during infection of G. mellonella were detected in larval hemolymph and these were enriched for biological processes such as interaction with host and pathogenesis. The candicidal activity of hemolymph after immediate incubation of yeast cells resulted in a decrease in yeast cell viability (0.23 ± 0.03 × 106, p < 0.05) as compared to control (0.99 ± 0.01 × 106). extracellular (in vivo) proteome of C. albicans in larval hemolymph were assessed. C. albicans responds to incubation in hemolymph ex vivo by the induction of an oxidative stress response, a decrease in proteins associated with protein synthesis and an increase in glycolytic proteins.

Project description:Using artificial Parafilm™ dummies, we explored the nutrition of V. destructor females and assessed their survival when fed on hemolymph from bee larvae, pupae or adults. We compared the results to fully synthetic solutions and to filtered larval plasma. The results showed that the parasites could survive for several days or weeks on our different diets. Hemolymph from larva yielded the highest survival rates and filtered cell-free hemolymph was sufficient to maintain the mites for 14 days or more. This cell free solution thus theoretically contains all necessary nutrients for the mite survival. A proteomic analysis on the larval plasma outlined a list of 54 proteins among which several energy metabolism proteins such as vitellogenin, hexamerin or transferrin. These molecules represent key candidate nutrients that could be crucial for V. destructor survival.

Project description:Human utilization of the mulberry-silkworm interaction started at least 5,000 years ago and greatly influenced world history through the Silk Road. Complementing the silkworm genome sequence, here we describe the genome of a mulberry species (Morus notabilis C. K. Schneider). In the 330 Mb genome assembly of M. notabilis, we identified 128 Mb of repetitive sequences and 29,338 genes, 60.8% of which were supported by transcriptome sequencing. Mulberry gene sequences appear to evolve ~3 times faster than other Rosales, perhaps facilitating its spread to Europe, Africa, and America. It is among few eudicots but several Rosales not preserving genome duplications in more than 100 million years – however neopolyploid series in mulberry and several others suggest that new duplications may confer benefits. Strikingly, five predicted mulberry miRNAs were found in the hemolymph and silkglands of silkworm, suggesting profound molecular level interactions that promise to expand knowledge of plant-herbivore relationship which constitute key elements of most terrestrial habitats. In addition, we investigated the characters of hemolymph small RNA. small mRNA profiles of silkworm hemolymph in the fifth instar day-5 silkworm were generated by deep sequencing, in twice, using Illumina Hiseq 2000.

Project description:We aimed to exemplify early and late transcriptional response of M. galloprovincialis to live Vibrio cells. Hemolymph was collected at 3 and 48 hours after the injection of 10 to 7 cells Vibrio splendidus LGP32 into the posterior adductor muscle. Hemolymph samples were similarly collected from paired control mussels injected with PBS-NaCl. The purified RNAs were successfully amplified, labelled and competitively hybridized to the new mussel oligoarray Immunochip 1.0.

Project description:Citrus greening disease, also known as Huanglongbing (HLB), is the most serious disease of citrus plants. It is associated with the Gram-negative bacterium ‘Candidatus Liberibacter asiaticus’ (CLas), which is transmitted between host plants by the hemipteran insect vector Diaphorina citri in a circulative, propagative manner involving specific interactions with various insect tissues, including the hemolymph, fluid that occupies the body cavity akin to insect blood. High resolution quantitative mass spectrometry was performed to investigate the effect of CLas exposure on D. citri hemolymph at the proteome level. In contrast to the broad proteome effects on hundreds of proteins and a diverse array of metabolic pathways previously reported in gut and whole insect proteome analyses, the effect of CLas on the hemolymph was observed to be highly specific, restricted to key immunity and metabolism pathways, and lower in magnitude than that previously observed in the whole insect body and gut. Vitellogenins were abundantly expressed and CLas-responsive. Gene-specific RNA expression analysis suggests that these proteins are expressed in both male and female insects, and may have roles outside of reproductive vitellogenesis. Proteins for fatty acid synthesis were found to be up-regulated, along with metabolic proteins associated with energy production, supported at the organismal level by the previously published observation that D. citri individuals experience a higher level of hunger when reared on CLas-infected plants. Prediction of post-translational modifications identified hemolymph proteins with phosphorylation and acetylation upon CLas exposure. Proteins derived from the three most prominent bacterial endosymbionts of the psyllid were also detected in the hemolymph, and several of these have predicted secretion signals. A DNAK protein, the bacterial HSP70, detected in the hemolymph expressed from Wolbachia pipientis was predicted to encode a eukaryotic nuclear localization signal. Taken together, these data show specific changes to immunity and metabolism in D. citri hemolymph involving host and endosymbiont proteins. These data provide a novel context for proteomic changes seen in other D. citri tissues in response to CLas and align with organismal data on the effects of CLas on D. citri metabolism and reproduction.

Project description:Purpose: With the advent of next generation sequencing technologies, several researches have been focused on the molecular mechanism underlying the innate immunity of insects based on the changes of gene expression profiles in hemolymph. The goal of this study is to detect the differences in transcript levels in A. pernyi hemolymph in response to ApNPV. Methods:The A. pernyi hemolymph infected by ApNPV and normal samples were generated by deep sequencing, in triplicate, using Illumina Hiseq 4000. The high-quality reads were obtained by removing the reads that contained adaptor contamination, low quality bases and undetermined bases.The transcriptome were de novo assembly. Results:We constructed six cDNA libraries using RNA samples from the hemolymph in ApNPV-infected and non-infected A. pernyi larvae with three replicates for each group. A total of 50459962, 49797542, 54402474 and 56342454, 56036432, 55471402 raw reads in ApNPV-infected and control groups were generated. After filtering, 48009732, 47241848, 51319586 and 53555764, 53364108, 53077540 clean reads were obtained. All short-read sequences were assembled into 49966 transcripts and 37498 unigenes. Conclusions: The transcriptome sequences were de novo assembled. The differentially expressed genes (DEGs) including both up- and down-regulated genes were obtained. We focused on the innate immunity related DEGs, and screened numerous of DEGs involved in cellular and humoral immune related pathways via bioinformatic analysis. The results of this study lay the foundation for a better understanding of the molecular mechanisms of cellular and humoral immunity of A. pernyi.
