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:Background: The soil environment is responsible for sustaining most terrestrial plant life on earth, yet we know surprisingly little about the important functions carried out by diverse microbial communities in soil. Soil microbes that inhabit the channels of decaying root systems, the detritusphere, are likely to be essential for plant growth and health, as these channels are the preferred locations of new root growth. Understanding the microbial metagenome of the detritusphere and how it responds to agricultural management such as crop rotations and soil tillage will be vital for improving global food production. Methods: The rhizosphere soils of wheat and chickpea growing under + and - decaying root were collected for metagenomics sequencing. A gene catalogue was established by de novo assembling metagenomic sequencing. Genes abundance was compared between bulk soil and rhizosphere soils under different treatments. Conclusions: The study describes the diversity and functional capacity of a high-quality soil microbial metagenome. The results demonstrate the contribution of the microbiome from decaying root in determining the metagenome of developing root systems, which is fundamental to plant growth, since roots preferentially inhabit previous root channels. Modifications in root microbial function through soil management, can ultimately govern plant health, productivity and food security.

Project description:To test the hypothesis that gene expression by the fungal partner in this beneficial interaction is modulated by the plant host, Trichoderma virens was co-cultured with maize or tomato in a hydroponic system allowing interaction with the roots. The transcriptomes for T. virens alone were compared with fungus-inoculated tomato or maize roots by hybridization on oligonucleotide microarrays Based on the relevant role of Trichoderma virens as a biological control agent this study provides a better knowledge of its crosstalk with plants in a host-specific manner. Trichoderma virens was co-cultured for three days with maize or tomato in a hydroponic system allowing interaction with the roots. 3 experiments were performed for each treatment, and compared to 5 experiments with T. virens grown under the same conditions without plants.

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 13,443 EST-derived transcripts (Trichochip-1) and the genomes of T. atroviride (11,100 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 (VizcaÃno et al., 2006). The Trichochip1 EST database was generated in the TrichoEST project funded by the EU (QLK3-CT-2002-02032). Confrontations were carried out between the T. harzianum T34 or nox1 overexpressed transformant Tnox5 and P. ultimum. Agar plugs cut from the growing edge of a 4-day colony of Trichoderma and Pythium were placed 2 cm from the border on the opposite side of the same petri plates containing PDA covered with sterile cellophane sheets. Dual cultures were allowed to grow at 25 ºC and mycelia were collected from the interaction zone in confrontations between P. ultimum and T. harzianum T34 or Tnox5 strains. Seven PDA plates were used for each condition considered and RNAs were extracted and the corresponding cDNAs were use to hybridize by triplicate the Trichoderma HDO microarray.

Project description:Marine microbial communities are critical for biogeochemical cycles and the productivity of ocean ecosystems. Primary productivity, at the base of marine food webs, is constrained by nutrient availability in the surface ocean, and nutrient advection from deeper waters can fuel photosynthesis. In this study, we compared the transcriptional responses by surface microbial communities after experimental deep water mixing to the transcriptional patterns of in situ microbial communities collected with high-resolution automated sampling during a bloom in the North Pacific Subtropical Gyre. Transcriptional responses were assayed with the MicroTOOLs (Microbiological Targets for Ocean Observing Laboratories) marine environmental microarray, which targets all three domains of life and viruses. The experiments showed that mixing of deep and surface waters substantially affects the transcription of photosystem and nutrient response genes among photosynthetic taxa within 24 hours, and that there are specific responses associated with the addition of deep water containing particles (organisms and detritus) compared to filtered deep water. In situ gene transcription was most similar to that in surface water experiments with deep water additions, showing that in situ populations were affected by mixing of nutrients at the six sampling sites. Together, these results show the value of targeted metatranscriptomes for assessing the physiological status of complex microbial communities.

Project description:Trichoderma harzianum T34 is a fungal strain able to promote the plant growth and to increase plant defense responses. Trichoderma harzianum transformants expressing the amdS gene, encoding an acetamidase, of Aspergillus nidulans produce a higher plant development than the wild type T34. We used microarrays to analyze the physiological and biochemical changes in tomato plants produced as consequence of interaction with Trichoderma harzianum T34 and amdS transformants

The Trichochip1 EST database was generated in the TrichoEST project funded by the EU (QLK3-CT-2002-02032) T. atroviride P1 mycelium grown (approximately for 24h) at 25ºC on a cellophane sheet on PDA (Difco) plates before contact (at a distance of 5 mm) a R. solani colony grown under identical conditions in the same plate was compared with T. atroviride P1 mycelium after contact (5 mm) the above R. solani colony (mycoparasitic interaction). RNAs from both conditions were extracted and the corresponding cDNAs were use to hybridize by triplicate the Trichoderma HDO microarray.

Project description:Although the nose, as a gateway for organism-environment interactions, may have a key role in asthmatic exacerbation, the rhinobiome of exacerbated children with asthma was widely neglected to date. Deep nasopharyngeal swab specimens, nasal epithelial spheroid cultures (NAEsp), and blood samples of acute exacerbated wheezers (WH), asthmatics (AB), and healthy controls (HC) were used for culture (n=146), 16 S-rRNA gene amplicon sequencing (n=64), proteomic and cytokine analyses. Interestingly, Proteobacteria were over-represented in WH (WH to AB: p=0.005; WH to HC: p=0.021), whereas Firmicutes and Bacterioidetes were associated with AB. In contrast, Actinobacteria commonly colonized HCs (PermANOVA p=0.005). Moreover, Staphylococcaceae (p<0.05), Enterobacteriaceae (p<0.05), Burkholderiaceae (p<0.05), Xanthobacteraceae (p<0.05), and Sphingomonadaceae (p<0.05) were significantly more abundant in AB compared to WH and HC. The α‐diversity analyses demonstrated an increase of bacterial abundance levels in atopic AB and a decrease in WH samples. Microbiome profiles of atopic WH differed significantly from atopic AB. The NAEsp bacterial exposure with M. catarrhalis, S. aureus and H. influenzae experiments provided a disrupted epithelial cell integrity, a cytokine release and cohort specific proteomic differences especially for M. catarrhalis cultures. Our comprehensive dataset contributes to a deeper insight into the poorly understood plasticity of the nasal microbiota, and, in particular, may enforce our understanding in the pathogenesis of asthma exacerbation in childhood.
