Project description:Endophytic bacteria influence plant growth and development and therefore are an attractive resource for applications in agriculture. However, little is known about the impact of these microorganisms on secondary metabolite (SM) production by medicinal plants. Here we assessed, for the first time, the effects of root endophytic bacteria on the modulation of SMs in the medicinal plant Lithospermum officinale (Boraginaceae family), with a focus on the naphthoquinones alkannin/shikonin (A/S). The study was conducted using a newly developed in vitro system as well as in the greenhouse. Targeted and non-targeted metabolomics approaches were used and supported by expression analysis of the gene PGT, encoding a key enzyme in the A/S biosynthesis pathway. Three bacterial strains, Chitinophaga sp. R-73072, Xanthomonas sp. R-73098 and Pseudomonas sp. R-71838 induced a significant increase of diverse SMs, including A/S, in L. officinale in both systems, demonstrating the strength of our approach for screening A/S derivative-inducing bacteria. Our results highlight the impact of root-endophytic bacteria on secondary metabolism in plants and indicate that production of A/S derivatives in planta likely involves cross-modulation of different metabolic pathways that can be manipulated by bacterial endophytes.

Project description:Xylem sap proteome studies on susceptible or resistant tomato (Solanum lycopersicum) inoculated with endophytic and/or pathogenic strains of Fusarium oxysporum f.sp. lycopersici were conducted to get insights into the molecular differences between endophyte- and R-gene-mediated resistance (EMR and RMR). The EMR and RMR proteomes were compared to each other and to the mock control. Interestingly, specific PR-5 isoforms were found to exclusively accumulate during endophyte or genetic resistance, providing excellent markers to distinguish both resistance types at the molecular level.

Project description:Conidial germination marks the beginning of the fungal life cycle, and understanding the genes associated with conidial germination provides insights into fungal pathogenicity and host interactions. Here, we use comparative transcriptomics to demonstrate the transcriptional similarities and differences during conidial germination and initial colony establishment in a plant pathogenic and an endophytic fungus, Fusarium graminearum and M. anisopliae, respectively. We compared the transcriptomes of F. graminearum and M. anisopliae across four stages of conidial germination: fresh conidia, polar growth, hyphal extension, and either first hyphal branching (on medium) or appressorium formation (on barley). F. graminearum exhibited a higher upregulation of CAZyme, specialized metabolite and effector genes compared to M. anisopliae during interaction with the host, particularly in the appressorium stage, reflecting its pathogenic nature. The appressorium structures formed when M. anisopliae conidia germinated on the host. The transcriptome analysis revealed that the fungus produced reduced transcript levels of CAZyme and specialized metabolite genes reflecting a less aggressive host penetration approach. The candidate genes associated with IAA synthesis were upregulated in M. anisopliae during the appressorium stage, supporting its endophytic lifestyle and suggests that the fungus uses a phytohormone based strategy to interact with plant hosts. Collectively, our findings expand the transcriptome resources and provide valuable insights into the gene networks involved in conidial germination and initiation of infection in pathogenic versus endophytic fungus.

Project description:Investigation of whole genome gene expression of the Fusarium fujikuroi wild type IMI58289 under gibberellin-inducing and -repressing conditions. Fusarium fujikuroi is a biotechnologically important fungus due to its almost unique ability to produce gibberellic acids (GAs), a family of phytohormones. The fungus was already described about 100 years ago as the causative agent of Bakanae (foolish seedling) disease of rice. Beside GAs, the fungus is known to produce some pigments and mycotoxins, but for only eight products the biosynthetic genes are known. Here we present a high-quality genome sequence of the first member of the Gibberella fujikuroi species complex (GFC), that allowed de novo genome assembly with 12 scaffolds corresponding to the 12 chromosomes. In this work, we focused on identification of all potential secondary metabolism-related gene clusters and their regulation in response to nitrogen availability by transcriptome, proteome, HPLC-FLPC and ChIP-seq analyses. We show that most of the cluster genes are regulated in a nitrogen-dependent manner, and that expression profiles fit to proteome and ChIP-seq data for some but not all clusters. Comparison with genomes of all available Fusarium species, including the recently sequenced F. mangiferae and F. circinatum, showed only a small number of common gene clusters and provides new insights into the divergence of secondary metabolism in the genus Fusarium. Phylogenetic analyses suggest that some gene clusters were acquired by horizontal gene transfer, while others were present in ancient Fusarim species and have evolved differently by gene duplications and losses. One PKS and one NRPS gene cluster are unique for F. fujikuroi. Their products were identified by combining overexpression of cluster genes with HPLC-FLPC -based product analyses. In planta, expression studies suggest a specific role of the PKS19 product in rice infection. Our results indicate that comparative genomics together with the used genome-wide experimental approaches is a powerful tool to uncover new secondary metabolites and to understand their regulation on the transcript, protein and epigenetic levels.

In this study, we hybridized in total 15 microarrays using total RNA recovered from wild-type cultures of F. fujikuroi IMI58289. Two cultures were grown on a 6 mM Gln medium. Additionally, two technical replicates were created. Four cultures were grown on a 60 mM Gln medium. Again, two technical replicates were created. On a 6 mM NO3 medium, three cultures were grown, and two cultures on a 120 mM NO3 medium, with no technical replicates. Each chip measures the expression level of 14,397 genes from F. fujikuroi IMI58289 with eight 60-mer probes.
