Expression array for Trichoderma atroviride in mycoparasitic interaction with Rhizoctonia solani

ABSTRACT: 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 (Vizcaíno et al., 2006). The Trichochip1 EST database was generated in the TrichoEST project funded by the EU (QLK3-CT-2002-02032)

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 25ÂºC 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.

Expression array for Trichoderma harzianum T34 and nox1 overexpressed transformant Tnox5 strains in dual culture with Pythium ultimum

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 ÂºC 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.

Comparative study of transcriptomes from four Trichoderma strains gene expression in early interaction with tomato 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 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 (VizcaM-CM--no 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). Eight samples were analyzed as follows: Strain T. reesei T6 grown in the presence or not of tomato plants, strain T. hamatum T7 grown in the presence or not of tomato plants, strain T. harzianum T34 grown in the presence or not of tomato plants and strain T. virens T87 grown in the presence or not of tomato plants. Three replicates for each samples were performed.

Gene expression response of the mycoparasite Trichoderma atroviride to confrontation with the host Rhizoctonia solani in the wild-type and tmk1 gene deletion mutants

Project description:Mycoparasitism is a key feature of Trichoderma biocontrol agents. Recent studies of intracellular signal transduction pathways of the potent mycoparasite Trichoderma atroviride revealed the involvement of Tmk1, a mitogen-activated protein kinase, in triggering the mycoparasitic response. We previously showed that mutants missing Tmk1 exhibit reduced mycoparasitic activity against several plant pathogenic fungi. In this study we identified the most robustly regulated targets governed by Tmk1 during mycoparasitism by whole transcriptome gene expression profiling using a custom microarray.
