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) 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.

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 (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).
