Transcriptional Profiles of the Human Pathogenic Fungus Paracoccidioides brasiliensis in Mycelium and Yeast Cells*
Paracoccidioides brasiliensis is the causative agent of paracoccidioidomycosis, a disease that affects 10 million individuals in Latin America. This report depicts the results of the analysis of… Expand
Transcriptome characterization of the dimorphic and pathogenic fungus Paracoccidioides brasiliensis by EST analysis
Paracoccidioides brasiliensis is a pathogenic fungus that undergoes a temperature‐dependent cell morphology change from mycelium (22° C) to yeast (36° C). It is assumed that this morphological… Expand
A truncated form of the Carbon catabolite repressor 1 increases cellulase production in Trichoderma reesei
BackgroundRut-C30 is a cellulase-hyperproducing Trichoderma reesei strain and, consequently, became the ancestor of most industry strains used in the production of plant cell wall-degrading enzymes,… Expand
Comparison of stem cell properties of cells isolated from normal and inflamed dental pulps.
AIM To compare cells from normal and inflamed human dental pulps regarding the presence of stem cells, their proliferation and differentiation potential. METHODOLOGY Human dental pulp stem cells… Expand
HDAC genes play distinct and redundant roles in Cryptococcus neoformans virulence
The human fungal pathogen Cryptococcus neoformans undergoes many phenotypic changes to promote its survival in specific ecological niches and inside the host. To explore the role of chromatin… Expand
The Relation Between Promoter Chromatin Status, Xyr1 and Cellulase Ex-pression in Trichoderma reesei
The ascomycete Trichoderma reesei is used for the production of plant cell wall-degrading enzymes in industrial scale. The interplay of the transactivator Xyr1 and the repressor Cre1 mainly regulates… Expand
Cloning, characterization and heterologous expression of the first Penicillium echinulatum cellulase gene
Aims:  Penicillium echinulatum is effective for bioconversion processes. However, nothing is known about the molecular biology of its cellulolytic system. We describe for the first time the… Expand
The impact of chromatin remodelling on cellulase expression in Trichoderma reesei
BackgroundTrichoderma reesei is used for industry-scale production of plant cell wall-degrading enzymes, in particular cellulases, but also xylanases. The expression of the encoding genes was so far… Expand
Thermophilic molds: Biology and applications
Abstract Thermophilic molds thrive in a variety of natural habitats including soils, composts, wood chip piles, nesting materials of birds and other animals, municipal refuse and others, and… Expand
Substrate-dependent differential expression of Humicola grisea var. thermoidea cellobiohydrolase genes.
Transcription of fungal cellulase genes may be affected by substrate induction. We studied the expression of Humicola grisea var. thermoidea cellobiohydrolase genes (cbh1.1 and cbh1.2) under… Expand
