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.

Project description:Insect gut microbiota plays important roles in acquiring nutrition, preventing pathogens infection, immune responses, and communicating with the environment. Gut microbiota can be affected by some external factors such as foods, temperature, and antibiotics. Spodoptera frugiperda (Lepidoptera: Noctuidae) is an important destructive pest of grain crops all over the world. The function of gut microbiota in S. frugiperda remains to be investigated. In this study, we fed the S. frugiperda with the antibiotic mixture (penicillin, gentamicin, rifampicin, and streptomycin) to perturb the gut microbiota, and further examined the effect of dysbiosis in gut microbiota on the gene expression of S. frugiperda by RNA sequencing. We found the composition and diversity of the gut bacterial community were changed in S. frugiperda after antibiotics treatmen, and the expression of genes related to energy and metabolic process were affected after antibiotics exposure in S. frugiperda. Our work will help understand the role of gut microbiota in insects.

Project description:A genomic insight into how an insect pest responds to the infection of a fungal insect pathogen, such as Beauveria bassiana, is critical for alternative strategy of insect pest contol based on fungal insecticides but has not been well probed. Here we constructed three pairs of digital expression libraries (transcriptomes) of Plutella xylostella (global lepidopteran pest) larvae 24, 36 and 48 hours post treatment of infection (hptI) and control (hptC) to reveal the host response to B. bassiana infection at genomic level. The paired libraries comprised 2144, 3200 and 2967 differentially expressed genes (DEGs) of P. xylostella at 24, 36 and 48 hptI/hptC, respectively. These DEGs were enriched in various immune pathways activated by the fungal infection, such as the pathways of complement and coagulation cascades, protein digestion and absorption, and drug metabolism - cytochrome P450. We found that 24 hptI was critical either for the cuticular penetration of B. bassiana or for the initial activation of the host defense system. The host immune response peaked at 36 hptI so that multiple defense mechanisms were activated against the fungal entry into the host hemocoel. At 48 hptI, many host genes involved in immunity and metabolism were downregulated, suggesting a success of fungal localization in the host hemocoel by overcoming the host defense reaction. Finally, we revealed that several fungal pathways could play important roles in the host-pathogen interaction, such as antioxidant activity, peroxidase activity and proteolysis. Up to 1636 fungal genes were co-expressed at the three time points, and 116 of them encode putative secretion proteins. Our results provide a novel insight into the pathogen-insect interaction and help to probe molecular mechanisms involved in the control of P. xylostella by B. bassiana. Here we constructed three pairs of digital expression libraries (transcriptomes) of Plutella xylostella (global lepidopteran pest) larvae 24, 36 and 48 hours post treatment of infection (hptI) and control (hptC) to reveal the host response to B. bassiana infection at genomic level

Project description:Tomato leafminer (Tuta absoluta) is a major pest of solanaceous plant species and causes heavy economic losses to the tomato crop. T. absoluta have been developed resistance to many chemical insecticides and have serious impacts on human health as well as environment. To overcome the ill effects of insecticides, ecofriendly approachis needed and among various biological microbes, entomopathogenic fungi is reliable and cost effective. The entomopathogenic fungi, like Beauveria bassiana and Purpureocillium lilacinum have ability to control pest population. The present study was conducted to study the interaction of B. bassiana and P. lilacinum at proteomic level to understand post infection effects. The analysis showed that in fourth instar larvae of T. absoluta, and the 442 and 423 proteins were significantly dysregulated upon infection with P. lilacinum and B. bassiana respectively. The present study concluded entomopathogenic fungal infection decline the immune system of T. absoluta larvae and can be adopted in for control of T. absoluta insect pest.

Project description:The large pine weevil Hylobius abietis L. is a major forestry pest in 15 European countries, where it is a threat to 3.4 million hectares of forest. A cellular and proteomic analysis of the effect of culture filtrate of three entomopathogenic fungi (EPF) species on the immune system of H. abietis was performed. Injection with Metarhizium anisopliae or Beauvaria bassiana culture showed significantly increased mortality highlighting that EPF culture filtrate has the potential to modulate the insect immune system allowing a subsequent pathogen to proliferate. Injection with EPF culture filtrate was shown to alter the abundance of protease inhibitors, detoxification enzymes, antimicrobial peptides and proteins involved in reception/detection and development in H. abietis larvae. Larvae injected with B. caledonica culture filtrate displayed significant alterations in abundance of proteins involved in cellulytic and other metabolic processes in their haemolymph proteome.

Project description:Entomopathogenic nematodes, the beneficial soil-dwelling nematodes identified with noteworthy ecological services of insect pest management naturally, harbor and vector obligate bacterial symbionts which together cause rapid insect mortality. The tritrophism among the bacterium-nematode-insect host is a treasure box of biological, molecular and biochemical information that was examined to a limited extent. In this project, we intend to explore the time-course expression of proteins of test insect, Holotrichia serrata larvae, during the progression of larval mortality due to nematode-bacterium infection, more specifically, Heterorhabditis indica-
Photorhabdus luminescens, Steinernema spp. vs Xenorhabdus spp., respectively. The data submitted relates to the insect protein profiles (LC-MSMS) in healthy, infected and morbid, and dead larvae of Holotrichia serrata.

Project description:N-glycosylation is one of the most abundant and conserved protein modifications in eukaryotes. This modification serves various important functions, such as protein folding and cellular attachment, but also modulation of a protein’s function. Recently, it has been shown that N-glycosylation of proteins plays a vital role in insect development and survival, which makes it an interesting target for pest control. Despite the importance of protein N-glycosylation in insects, not much is known about insect N-glycoproteomes. Here, we report on the N-glycoproteomes of three major pest insects spanning different insect orders; Drosophila melanogaster (Diptera), Tribolium castaneum (Coleoptera) and Acyrthosiphon pisum (Hemiptera). The number of identified N-glycosylation sites ranged from 889 in T. castaneum, to 941 in D. melanogaster and 1,338 in A. pisum. Comparison between the different insect species revealed both conserved and species-specific glycoproteins. The functionality of the insect glycoproteins together with the conservation of the N-glycosites throughout evolution are discussed. This information can help in the elaboration of novel pest insect control strategies based on interference in insect glycosylation.

Project description:Plant growth promoting rhizobacteria (PGPR) induce positive effects in plants, such as increased growth or reduced stress susceptibility. The mechanisms behind PGPR/plant interaction are poorly understood, as most studies have described short- term responses on plants and only a few studies have analyzed plant molecular responses under PGPR colonization. Transcriptional profiles were determined by microarray analysis (Affymetrix ATH1 Genome Array) in Arabidopsis thaliana plants inoculated with the PGPR bacterial model Burkholderia phytofirmans PsJN Arabidopsis seeds were sown on square Petri dishes with half strength Murashige and Skoog medium (MS) 0.8% agar, and inoculated or not (control) with strain PsJN. To assess the effect of inactivated bacteria, an inoculum was heated at 95M-BM-0C for 20 min and then was used at the same dilution.Three biological replicates, consisting of ten plantlets of 13 days after sowing (DAS) each, for control and strain PsJN treatments, were used for global gene expression.
