Metabolomics of the interaction between a consortium of entomopathogenic fungi and their target insect: mechanisms of attack and survival

ABSTRACT: One of the most concerning pests that attack strawberries in Brazil is Duponchelia fovealis, a non-native moth with no registered control methods to date. Our group recently observed that a fungal consortium formed by two strains of Beauveria bassiana increased the mortality of D. fovealis more than inoculation with each strain on its own. However, the molecular interaction between the fungal consortium and the caterpillars is unknown, raising several questions about the enhanced pest control observed. Furthermore, concerns over the emergency of resistance and the selection for resistance to chemical and biological products that are constantly applied in agriculture highlight the need for careful examination of novel pest control methods. Thus, in this work, we sought to pioneer the evaluation of the molecular interaction between a fungal consortium of B. bassiana and D. fovealis caterpillars. We aimed to understand the biocontrol process involved in this interaction and the defense system of the caterpillar. Therefore, seven days after D. fovealis caterpillars were inoculated with the B. bassiana consortium, the dead and surviving caterpillars were analyzed using GC-MS and LC-MS/MS.

Project description:Fusarium oxysporum is one of the most common species causing soybean root rot and seedling blight in the U.S. In a recent study, significant variation in aggressiveness was observed among isolates of F. oxysporum collected from roots in Iowa, ranging from highly pathogenic to weakly or non-pathogenic isolates. In the present work, a RNA-seq-based analysis was used for the first time to investigate the molecular aspect of the interaction of a partially resistant soybean genotype with non-pathogenic/pathogenic isolates of F. oxysporum at 72 and 96 hours post inoculation (hpi). Markedly different gene expression profiles were observed in compatible and incompatible host-pathogen combinations. A peak of differentially expressed genes (DEGs) was observed at 72 hpi in soybean roots in response to both isolates, although the number of DEGs was about eight times higher for the pathogenic isolate compared to the non-pathogenic one (1,659 vs. 203 DEGs, respectively). Furthermore, not only the number of genes, but also the magnitude of induction was much greater in response to the pathogenic isolate. This response included a stronger activation of many well-known defense-related genes, and several genes involved in ethylene biosynthesis and signalling, transcription factors, secondary and sugar metabolism. In addition, 1130 fungal genes were differentially expressed between the F. oxysporum isolates in planta during the infection process. Interestingly, 10% of these genes encode plant cell-wall degrading enzymes, reactive oxygen species-related enzymes and fungal proteins involved in primary metabolic pathways. Such information may be useful in the development of new methods of broadening resistance of soybean to F. oxysporum, including the silencing of important fungal genes, and also to understand the molecular basis of soybean-F. oxysporum interactions. Soybean seedlings mRNA profiles inoculated with a non-pathogenic and pathogenic isolates of F. oxysporum and collected at 72 and 96 hpi, were generated using Illumina HiSeq 2500. Control seedlings were also included for each time of inoculation. Three biological replicates were considered for each condition, 18 samples in total.

Project description:Candida albicans is the major invasive fungal pathogen of humans, causing diseases ranging from superficial mucosal infections to disseminated, systemic infections which are often life threatening. Hematogenously disseminated candidiasis (HDC) has a 47% mortality rate despite current antifungal therapy. An increase in prevalence, as well as an increasing resistance to most of the clinically important antifungal therapies, provides a strong impetus to understand the molecular mechanisms of pathogenesis and the acquisition of drug resistance. This information holds promise to identify novel therapeutic targets. A complete and accurate characterization of how the transcriptome of C. albicans responds to its interaction with cells from the host is an absolute necessity to accomplish this goal. RNA-seq (deep-sequencing of cDNA) provides an unbiased method to define comprehensively and systematically the transcriptome of an organism. We propose a comprehensive characterization of the C. albicans transcriptome in two different human tissue culture models, using RNA-seq. Such a characterization will shed unprecedented light on how fungal pathogens sense and respond to the host environment and how the host tissue responds to fungal invasion. We performed a comprehensive characterization of the C. albicans transcriptome in two different murine models of candidiasis (HDC and oropharyngeal candidiasis (OPC)), and two different human tissue culture models, using RNA-seq. Because the two murine models accurately recapitulate the pathology that is observed in clinical cases of candidiasis, we are confident that gene expression levels will provide an accurate representation of what occurs during the course of an infection in humans. Such a characterization of the in vivo transcriptome will shed unprecedented light on how fungal pathogens sense and respond to the host environment and how the host tissue responds to fungal invasion. PRJNA86065 Two different strains of C. albicans (SC5314 or WO-1) were used to infect two different types of human tissue culture monolayers (HUVECs or OKF6-TERT2). RNA from the infection mixtures were harvested at 90 minutes, 5 hours and 8 hours post infection. Experiments were performed in biological duplicate.
