Project description:We report Illumina-generated RNASeq data of several populations of Tribolium castaneum larvae selected for higher or lower immune priming specificity as well as unselected control populations. From each of these populations, we injected groups of 20 larvae with either one of three bacteria species or left them untreated as controls. Whole body samples were taken 6h after injection and used for RNASeq Analysis.

Project description:This study examines gene expression differences between infected larvae from different maternal infection backgrounds to try to understand the immunological basis of invertebrate immune priming. Female Tribolium castaneum beetles were either jabbed with sterile saline, heat killed Bt, or left naïve. 15 Offspring from the first and second broods were infected with Bt and 24 hours later pooled by treatment and flash frozen Beetles from saline and primed maternal backgrounds are compared to naïve infected

Project description:Group-living individuals experience immense risk of disease transmission and parasite infection. In social and in some non-social insects, disease control with immunomodulation arises not only via individual immune defenses, but also via infochemicals such as contact cues and (defensive) volatiles to mount a group-level immunity. However, little is known about whether activation of the immune system elicits changes in chemical phenotypes, which may mediate these responses. We here asked whether individual immune experience resulting from wounding or injection of heat-killed Bacillus thuringiensis (priming) leads to changes in the chemical profiles of female and male adult red flour beetles, Tribolium castaneum, which are non-social but gregarious. We analyzed insect extracts using GC-FID to study the chemical composition of (1) cuticular hydrocarbons (CHCs) as candidates for the transfer of immunity-related information between individuals via contact, and (2) stink gland secretions, with analysis of benzoquinones as main active compounds regulating ‘external immunity’. Despite a pronounced sexual dimorphism in CHC profiles, wounding stimulation led to similar profile changes in males and females with increases in the proportion of methyl-branched alkanes compared to naïve beetles. While changes in the overall secretion profiles were less pronounced, absolute amounts of benzoquinones were transiently elevated in wounded compared to naïve females. Responses to priming were insignificant in CHCs and secretions. We suggest that changes in different infochemicals after wounding may mediate immune status signaling in the context of both internal and external immune responses in groups of this non-social insect, thus showing parallels to social immunity.

Project description:Using a tiled whole-genome microarray, we found that 58.2% of Tribolium castaneum genes are maternally loaded into eggs. Comparison of known Drosophila melanogaster maternal genes to our results showed widespread conservation of maternal function with T. castaneum. We also found many T. castaneum genes with previously identified gender or tissue specific expression were also maternally loaded into eggs. The microarray design also allowed the detection of 2315 and 4060 novel transcriptionally active regions greater in length than 100 bp in unfertilized and fertilized T. castaneum eggs, respectively. The primary objective of this study was to identify expressed regions of the Tribolium castaneum genome in unfertilized and fertilized eggs using a whole-genome tiled microarray. The whole RNA of 3 samples of virgin laid eggs and 3 samples of fertilized eggs were compaired.

Project description:Neuropeptides and neurohormones are among the more diverse and functionally important classes of cell-to-cell signaling molecules involved in animal development and behavior. Less is known about the hormones and neuropeptides of the red flour beetle, Tribolium castaneum, than many other insects. However, the genomic information becoming available from this organism presents an opportunity to identify multiple neuropeptide and hormone genes, and hence their associated protein precursors. Using similarity-based prediction, we report new neuropeptides and hormone precursors from T. castaneum, bringing the number of annotated precursors to 37. We identified one prohormone (SVDPIDGDLIG-containing) having little similarity to other insect prohormones. The conversion of the protein precursors into bioactive peptides requires a suite of processing enzymes and a number of enzymatic steps; using the web-based NeuroPred application and similarity-based bioinformatics approaches, we predict 132 likely peptides that may result from the enzymatic processing of these gene products.

Project description: Bacillus thuringiensis Cry toxin is used for insect pest management. When susceptible insect larvae ingest the Bt toxin it shows various physiological and cellular changes. We have employed Agilent One Color matrix based microarray to check the mid-gut gene expression upon Cry toxin exposure in Achaea janata (Castor semilooper). Microarray analysis shows significant variation in gene expression upon Cry toxin exposure.
