Project description:Many Trichoderma spp. are successful plant beneficial microbial inoculants due to their ability to act as biocontrol agents with direct antagonistic activities to phytopathogens, and as biostimulants capable of promoting plant growth. This work investigates the effects of treatments with three selected Trichoderma (strains T22, TH1 and GV41) to strawberry plants on the productivity and proteome of the formed fruit. Proteomic analysis of fruits,harvested from the plants previously treated with Trichoderma and control plants was performed by using a TMT-based protein quantification strategy. Bioinformatic analysis of the differential proteins accumulation in fruits, harvested from the treated plants, revealed a central network of interacting molecular species, that demonstrated the modulation of different plant physiological processes following the microbial inoculation.

Project description:Trichoderma spp. are versatile opportunistic plant symbionts which can colonize the apoplast of plant roots. Microarrays analysis of Arabidopsis thaliana roots inoculated with Trichoderma asperelloides T203, coupled with qPCR analysis of 137 stress-responsive genes and transcription factors, revealed wide gene transcript reprogramming, preceded by a transient repression of the plant immune responses supposedly to allow root colonization. Enhancement in the expression of WRKY18 and 40, which stimulate JA-signaling via suppression of JAZ repressors and negative-regulate the expression of the defense genes FMO1, PAD3 and CYP71A13, was detected in Arabidopsis roots upon Trichoderma colonization. Reduced root colonization was observed in the wrky18/wrky40 double mutant line, while partial phenotypic complementation was achieved by over-expressing WRKY40 in the wrky18 wrky40 background. On the other hand, an increased colonization rate was found in roots of the FMO1 knockout mutant. Two-condition experiment: Roots treated with Trichoderma vs. Control untreated roots. Biological replicates: 2 control replicates, 2 treated replicates. 1 dye-swap.

Project description:Combating the action of plant pathogenic microorganisms by antagonistic or mycoparasitic fungi has been announced as an attractive biological alternative to the use of chemical fungicides since more than 20 years, and gains additional importance in current trends to environmentally friendly agriculture. Taxa of the fungal genus Hypocrea/Trichoderma (Ascomycota, Hypocreales, Hypocreaceae) contain prominent examples of such biocontrol agents, because they not only antagonize plant-pathogenic fungi, but are also often rhizosphere competent and can enhance plant growth. Identification of the primary factors that regulate the mycoparasitic behaviour and metabolic activities related to it will therefore allow the full ecological significance of this trait to be explored. We performed the analysis of the genome sequence from two mycoparasitic and rhizosphere competent Trichoderma spp. – T. atroviride and T. virens – and compare it to that of the saprophyte T. reesei. The predicted gene inventory of the T. atroviride and T.virens genome, therefore, points to previously unknown mechanisms operating during biocontrol of plant pathogens. The availability of these genomes provides a unique opportunity to develop a deeper understanding of the processes fundamental to mycoparasitism and its application for the breeding of improved biocontrol strains for plant protection. To investigate the potential role in mycoparasitism, microarrays were used to examine T. virens transcript levels when confronted with a potential prey (the plant pathogen Rhizoctonia solani) before contact, during first physical contact and during overgrowth of the host. The study presented here is the result of this analysis.

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).

Project description:Trichoderma spp. are ubiquitous soil-borne ascomycetous fungi that have been used widely in the biological control of plant diseases. Certain strains also exhibit growth promotion of plants, but the mechanism for this phenomenon has not yet been elucidated. We have recently identified an isolate of T. hamatum that causes significant increases in the development of Arabidopsis root systems. The aim of this work is to elucidate the mechanism of root growth promotion. One approach is to analyse the transcriptome of plants grown in the presence and absence of the fungus.
