Project description:In order to study the inhibition mechanism of volatile organic compounds produced by Xenorhabdus bovienii on Fusarium solani (NK-NH1), we selected the inhibited and uninhibited Fusarium solani mycelia for transcriptome sequencing, and tried to find the corresponding inhibition mechanism at the gene level.

Project description:Fusarium spp. are fungal pathogens of humans and plants. Fusarium oxysporum and Fusarium solani are important species isolated from infections such as onychomycosis, fungal keratitis, invasive infections, and disseminated diseases. These pathologies have a very difficult therapeutic management and poor therapeutic responses, especially in patients with disseminated infection. Little information is available regarding the molecular mechanisms responsible for antifungal resistance in these fungi. methods: In this study, we performed a quantitative analysis of the transcriptional profile of F. oxysporum and F. solani, challenged with amphotericin B (AMB) and posaconazole (PSC) using RNA-seq. Quantitative real-time reverse transcription PCR (qRT-PCR) was used to validate the results results: Several genes related to mechanisms of antifungal resistance such as efflux pumps, ergosterol pathway synthesis, and responses to oxidative stress were found. Genes such as ERG11, ERG5, the Major Facilitator Superfamily (MFS), thioredoxin, and different dehydrogenase genes may explain the reduced susceptibility of Fusarium spp. against azoles and the possible mechanisms that may play an important role in induced resistance against polyenes. conclusions: Important differences in the levels of transcriptional expression were found between F. oxysporum and F. solani exposed to the two different antifungal treatments. Knowledge on the gene expression profiles and gene regulatory networks in Fusarium spp. during exposure to antifungal compounds, may help to identify possible molecular targets for the development of novel, better, and more specific therapeutic compounds. profile transcriptional of Fusarium spp changed to antifungal treatments in vitro

Project description:We present the first results of a high coverage Dual RNA-Seq experiment of an R. solani AG1-IB 7/3/14 and L. sativa interaction model with focus on the R. solani transcriptome. With this experiment it is our goal to expand the knowledge regarding the pathosystem L. sativa R. solani AG1-IB through the determination of genes, of pivotal importance for this interaction and who can therefore be seen as putative pathogenicity determinants of R. solani infection within this specific host species.

Project description:Allyl isothiocyanate (AITC) is a natural product used as a food additive. Due to its strong volatility and broad biological activity, AITC is being considered as a bio-fumigant to control soil-borne fungal diseases in agriculture, creating an urgent need for evaluation of the antifungal activity of AITC. Here, AITC-trigged growth inhibition, sensing, and related molecular mechanisms were analyzed in Fusarium solani by employing morphological, genetic, and transcriptional profiling analysis. The results indicated that AITC causes rapid inhibition of F. solani after 5 min, hyphal deformity, and electrolyte leakage. A yeast-like vacuolar transient receptor potential channel regulator (FsYvc1, a STRPC family member) was identified in F. solani that is play a switch role for sensing AITC. Genetic evidence suggests the gene FsYvc1 involved in growth, development, and pathogenicity. Loss of FsYvc1 resulted in hypersensitivity of F. solani to AITC and high levels of reactive oxygen species with weak responses to CaCl2, NaCl, KCl, SDS, and Congo red as well as triadimefon, triadimenol, chlorothalonil, and azoxystrobin. Transcription profiling and qRT-PCR showed that three transcripts were up-regulated in the wild type (WT) but down-regulated in the FsYvc1 mutants (∆FsYvc1), which were involved in TRP ion channel expression, biosynthetic process, and oxidoreductase activity. Three transcripts down-regulated in WT but up-regulated in the ∆FsYvc1 were involved in metabolic process, proper enzyme folding (GrpB protein), and the response to abiotic stress (WD40 repeat). This study provides novel insights into the toxicity mechanisms of AITC. Considering the key role of FsYvc1, it could act as a new molecular target for future fungicide development.

Project description:Rhizoctonia solani is a nectrotrophic fungal pathogen that causes billions of dollars of damage to agriculture worldwide and infects a broad host range including wheat, rice, potato and legumes. In this study we identify wheat genes that are differentially expressed in response to the R. solani isolate, AG8-1, using microarray technology. A significant number of wheat genes identified in this screen were involved in ROS production and redox regulation. Levels of ROS species were increased in wheat root tissue following R. solani infection as determined by NBT, DAB and titanium sulphate measurements/stainings. Pathogen/ROS related genes from R. solani were also tested for expression patterns upon wheat infection. TmpL, a R. solani gene homologous to a gene associated with ROS regulation in Alternaria brassicicola, and OAH, a R. solani gene homologous to oxaloacetate acetylhydrolase which has been shown to produce oxalic acid in Sclerotinia sclerotiorum, were highly induced in R.solani when infecting wheat. We speculate that the wheat germin-like protein (GLP) is induced to inactivate the oxalic acid that is produced by the R. solani OAH.
