(Submitter supplied) Lactose (1,4-0-ß-d-galactopyranosyl-d-glucose), a by-product from cheese manufacture or whey processing industries, is known to induce the formation of plant biomass hydrolyzing enzymes needed for the biorefinery industry in the fungus Trichoderma reesei, but the reason for this induction and the underlying mechanism are not fully understood. Here, we used systems analysis of the Trichoderma reesei transcriptome during utilization of lactose. more...

(Submitter supplied) The filamentous fungus Trichoderma reesei is a saprophyte involved with polysaccharides cell wall depolymerization, being the most important industrial source of cellulases, which have been used for bioethanol production. The regulation of cellulase expression is controlled at the transcriptional level and in a carbon source-dependent manner. However, the signaling pathways and mechanisms involved in regulating the expression of these enzymes in T. more...

(Submitter supplied) The ascomycete Trichoderma reesei is an industrial producer of cellulolytic and hemicellulolytic enzymes and also serves as a model for investigations on these enzymes and their genes. Most of them are obligatorily dependent on the Zn(II)Cys(VI) transcriptional activator XYR1. XYR1 is constitutively expressed at a low basal, but induced in the presence of cellulase- and hemicellulose inducers, and transported into the nucleus. more...

(Submitter supplied) The mitosporic fungus Trichoderma reesei is an industrial producer of enzymes for degradation of lignocellulosic polysaccharides to soluble monomers that can be fermented to biofuels. The genes encoding these enzymes in T. reesei have recently been shown to be clustered in the genome. Here we will show that the expression of these genes is epigenetically controlled at the heterochromatin level by the protein methyltransferase LAE1. more...

(Submitter supplied) The ascomycete Trichoderma reesei is one of the most well studied cellulolytic fungi and widely used in the biotechnology industry, as in the production of second-generation bioethanol. Carbon catabolite repression (CCR) mechanism adopted by T. reesei is mediated by the transcription factor CRE1 and consists in the repression of genes related to the production of cellulase when a readily available carbon source is present in the medium. more...

(Submitter supplied) Investigation of whole genome gene expression level changes in response to different light conditions of the T. reesei QM9414 deletion strains delta-blr1, delta-blr2 and delta env1 cultivated on 1% microcrystalline cellulose. Perception and proper interpretation of environmental signals is crucial for survival in any natural habitat. Although the biotechnological workhorse Trichoderma reesei (Hypocrea jecorina) is predominantly known for its capability of efficient plant cell wall degradation, recent studies show that it has not lost its evolutionary heritage. more...

(Submitter supplied) Light represents an important environmental cue, which exerts considerable influence on the metabolism of fungi. Studies with the biotechnological fungal workhorse Trichoderma reesei (Hypocrea jecorina) have revealed an interconnection between transcriptional regulation of cellulolytic enyzmes and the light response. The filamentous fungus, Neurospora crassa, has been used as a model organism to study light and circadian rhythm biology. more...

(Submitter supplied) The asexual spore or conidium plays a critical role in the life cycle of many filamentous fungi, being the primary means for dispersion in the environment. To investigate the transcriptional changes taking place during the sporulation phase in T. reesei, which culminates with the production of the conidiospores, microarray experiments were performed. Among the 1,994 distinct genes displaying >90 % confidence , a total of 900 were classified as differentially expressed, relative to time zero of sporulation, at at least one of the time points analyzed. more...

(Submitter supplied) We have examined and compared the transcriptome of T. reesei growing on wheat straw and lactose as carbon sources under otherwise similar conditions. Gene expression on wheat straw exceeded that on lactose, and 1619 genes were found to be only induced on wheat straw but not on lactose. They comprised 30 % of the CAZome, but were also enriched in genes associated with phospholipid metabolism, DNA synthesis and repair and iron homeostatis. more...

(Submitter supplied) The filamentous fungus Trichoderma reesei is the main industrial cellulytic enzymes producer. Several strains have been developed in the past using random mutagenesis, and despite impressive performance enhancements, the pressure for low-cost cellulases has stimulated continuous research in the field. In this context, comparative study of the lower and higher producer strains obtained through random mutagenesis using systems biology tools (genome sequencing, transcriptome) can shed light on the mechanisms of cellulase production and help identify genes linked to performance. more...

(Submitter supplied) Trichoderma reesei is known for its ability to produce large amounts of extracellular proteins and is one of the most important industrially used filamentous fungus. Xylanase regulator 1 (XYR1) as the master regulator is responsible for the activation of cellulase and hemicellulase gene expression, normally under inducing conditions. It has been reported that strains with point mutations in certain areas of xyr1 bypass the carbon catabolite repression, allowing cellulase and hemicellulase production even in the presence of glucose. more...
