Project description:Trichoderma erinaceum secretome The use of lignocellulosic biomass is something that has been encouraged considering the search for sustainable alternatives mainly in the energy sector. However, to use such biomass as feedstock, its degradation is necessary aiming the formation of sugars that could be used in fermentation. For this conversion, enzymatic cocktails with degradative capacity are used, which are normally composed for the of filamentous fungi secretomes. The present work presents the characterization of Trichoderma erinaceum aiming at its use as a producer of lignocellulolytic enzymes. Cultivations were conducted using Mandels-Andreotti media enriched with four different carbon sources (glucose, avicel, pretreated sugarcane straw, or energy cane bagasse) in different time points (72h, 96h, 120h, 144h), and the supernatants were analyzed by mass spectrometry to determine the various patterns of enzyme secretion resulting from the modification of components within the media.

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.

Project description:Trichoderma species promote growth and strengthen immunity of Arabidopsis and crop species through multiple mechanisms. However, how fungal proteins mediate growth-defense tradeoffs is unknown. We analyzed the growth, root architecture, defense and global gene expression profiles in Arabidopsis seedlings co-cultivated with T. atroviride WT, and Δnox1, Δnox2, and ΔnoxR mutants, defective on the catalytic and regulatory subunits of NADPH oxidase, respectively. The gene expression profile in the fungus was also characterized in standard growth conditions and in the presence of plants. The results revealed the critical role of Trichoderma NoxR in mediating growth-defense tradeoffs in Arabidopsis. The effects of T. atroviride WT in improving root branching and biomass production decreased in all three related NADPH defective mutants, particularly in ΔnoxR. In contrast, induction of jasmonic acid-related defense responses in roots and shoots were exacerbated in ΔnoxR compared to the WT strain. Transcriptome analyses showed a tight plant-fungus communication based on reactive oxygen species and availability of carbon resources. The ΔnoxR is unable to perceive changes in nutrient sources and activate signaling cascades, which suppresses the metabolic change from saprophyte to commensal. Thus we conclude that Trichoderma NoxR orchestrates fungal-induced development and defense tradeoffs in Arabidopsis and plays an important role in cross-kingdom plant-fungus communication.

Project description:In this study, we have developed a highly SO2-stress-resistant yeast (Saccharomyces cerevisiae) strain [F3] using evolutionary engineering, by successive batch selection at gradually increased SO2 levels. The evolved F3 strain was resistant to 1.0 mM SO2 stress, which was strongly inhibitory to the reference strain. Whole-transcriptomic analysis of F3 was performed with respect to its reference strain to determine differences in gene expression levels between the two strains. Saccharomyces cerevisiae

Project description:The goal of this study is to find novel regulatory details of plant biomass-degrading enzymes in filamentous fungus Trichoderma guizhouense NJAU4742. Strain NJAU4742 and its mutants (∆Tgxyr1,∆Tgace1 and ∆Tgace2) were firstly incubated using 2% glucose, and then transfered into the medium containing different polysaccharides (xylan or cellulose) or carbon starvation. After 0h, 4h, 24h or 72h, samples were extracted and used for transcriptome sequencing in Illumina platform.

Project description:The Aspergillus niger genome contains a large repertoire of genes encoding carbohydrate active enzymes (CAZymes) that are targeted to plant polysaccharide degradation enabling A. niger to grow on a wide range of plant biomass substrates. Which genes need to be activated in certain environmental conditions depends on the composition of the available substrate. Previous studies have demonstrated the involvement of a number of transcriptional regulators in plant biomass degradation and have identified sets of target genes for each regulator. In this study, a broad transcriptional analysis was performed of the A. niger genes encoding (putative) plant polysaccharide degrading enzymes. Microarray data focusing on the initial response of A. niger to the presence of plant biomass related carbon sources were analyzed of a wild-type strain N402 that was grown on a large range of carbon sources and of the regulatory mutant strains ΔxlnR, ΔaraR, ΔamyR, ΔrhaR and ΔgalX that were grown on their specific inducing compounds.

Project description:Lactose (1,4-0-M-CM-^_-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. We found that the respective CAZome encoded glycosyl hydrolases specifically tailored for the attack of monocotyledon xyloglucan. In addition, genes for a high number of putative transporters of the major facilitator superfamily were also induced. Systematic knock out of them identified a gene whose knock-out completely impaired lactose utilization and cellulase induction in Trichoderma reesei. These data shed new light on the mechanism by which Trichoderma reesei metabolizes lactose and illuminate the key role of M-CM-^_-D-galactosides in habitat specificity of this fungus. We used two biological replicas of Trichoderma reesei growing on lactose, glucose and glycerol
