Project description:We report the application of RNA sequencing technology for transcriptome profiling of Trichoderma asperellum challenged with Organophosphorus Pesticide Dichlorvos. Based on RNA-seq analysis, in T. asperellum TJ01 treated with 100 μg/mL, 500 μg/mL, and 1000 μg/mL dichlorvos, 204, 490, and 872 genes were significantly upregulated, respectively, while 37, 177, and 383 genes were significantly downregulated, respectively. This study provides a framework for the application of transcriptome profiling towards characterization of trichoderma under stress of Organophosphorus Pesticide.
Project description:<p><em>Phytophthora nicotianae</em> is an oomycete pathogen of global significance threatening many important crops. It is mainly controlled by chemosynthetic fungicides, which endangers ecosystem and human health; thus, there is an urgent need to explore alternatives for these fungicides. In this study, a new anti-oomycete aliphatic compound was obtained through co-culture of <em>Bacillus subtilis</em> and <em>Trichoderma asperellum</em>. The action mode of this natural product on <em>P. nicotianae</em> was preliminarily explored by using transcriptome, metabolome and physiological index detection.</p>
Project description:A self-designed Trichoderma high density oligonuclotide (HDO) microarray (Roche-NimbleGen, Inc., Madison, WI, USA) was constructed in a similar way than a previous Trichoderma HDO microarray (Samolski et al., 2009). The microarray was composed of 392,779 60-mer probes designed against 14,081 EST-derived transcripts (Trichochip-1) and the genomes of T. reesei (9,129 genes) and T. virens (11,643 genes). The Trichochip-1 ESTs were obtained from 28 cDNA libraries from eight different species (representing the biodiversity of this genus: T. harzianum, T. atroviride, T. asperellum, T. viride, T. longibrachiatum, T. virens, T. stromaticum and T. aggresivum), under a wide range of growth conditions, including biocontrol-related conditions and different nutritional situations (Vizcaíno et al., 2006). This HDO microarray was used to analyze Trichoderma spp. transcriptomes after 20 h incubation in the presence of tomato plants. The Trichochip1 EST database was generated in the TrichoEST project funded by the EU (QLK3-CT-2002-02032).
