Project description:We perform a self hybridisation comprative genomic hybridization (CGH) in order to validate the probe tiling design we done on Trichoderma reesei. This hybridization was done using QM6a wild type strain.

Project description:In this study, the recombinant Trichoderma reesei strain HJ48 was employed to investigate the differences between anaerobic and aerobic fermentation of glucose, through genome-wide transcription analysis.Analysis of the genes induced under fermentation condition has revealed novel features in T. reesei. Our results how that many genes related to ribosome were expressed more highly under aerobic condition in HJ48.
Project description:Trichoderma reesei is the main industrial producer of cellulases and hemicellulases used to depolymerize biomass in many biotechnical applications. Many production strains in use have been generated by classical mutagenesis. In this study we characterized genomic alterations in hyperproducing mutants of T. reesei by high-resolution comparative genomic hybridisation tiling array. We carried out aCGH analysis of four hyperproducing strains (QM9123, QM9414, NG14 and RutC-30) using QM6a genome as a reference. ArrayCGH analysis identified dozens of mutations in each strain analyzed.

ArrayCGH analysis identified dozens of mutations in each strain analyzed. 2.1 million oligonucleotide probe custom aCGH (HD2 format, RocheNimblegen) was designed according to T. reesei strain QM6a genome v2.0 (http://genome.jgi-psf.org/Trire2/Trire2.home.html). 14 samples are included in this set; 3 replicates of each strain (except two replicates of QM9123) were analyzed (four mutant strains and QM6a control strain for self-hybridization)
Project description:Investigation of whole genome gene expression level changes in response to different light conditions of the T. reesei QM9414 parental strain and the deletion strains delta-phlp1, delta-gnb1 and delta gng1, cultivated on 1 % microcrystalline cellulose. The mutants analyzed in this study are further described in Tisch et al. 2011: Carbohydrate degradation is significantly regulated by light and the phosducin like protein PhLP1 in Trichoderma reesei (Hypocrea jecorina).
Project description:We investigated the function of the G-protein coupled receptor 72004 in Trichoderma reesei and found that it is involved in methionine response and gene expression in light and darkness

The mutants analyzed in this study are further described in Tisch et al. 2011: Carbohydrate degradation is significantly regulated by light and the phosducin like protein PhLP1 in Trichoderma reesei (Hypocrea jecorina). We used two biological replicates of four T. reesei strains (QM9414, delta-phlp1, delta-gnb1 and delta-gng1), cultivated in constant light (LL, 1800 lux) or constant darkness (DD) on microcrystalline cellulose.
