(Submitter supplied) Filamentous fungi are one of the primary degraders of plant biomass because of their ability to produce enzymes that break down complex polysaccharides. The production of cellulolytic enzymes in fungi is dependent on transcription factors. In this article, we identified a N. crassa Zn2Cys6 transcription factor Clr5 that regulates the expression of cellulase on cellulose. N. crassa Δclr5 exhibited a significant decrease in secreted proteins (~46%), endo-glucanase (~55%), xylanase (~33%), β-glucosidase (~38%), and exocellulase (~40%) compared with the WT, while transcriptomic analysis revealed that clr5 was essential in cellulase expression. more...

(Submitter supplied) In filamentous ascomycete fungi, the utilization of alternate carbon sources is influenced by the zinc finger transcription factor CreA/CRE-1, which encodes a carbon catabolite repressor protein homologous to Mig1 from Saccharomyces cerevisiae. In Neurospora crassa, deletion of cre-1 results in increased secretion of amylase and β-galactosidase. Here, we determined the CRE-1 regulon by investigating the transcriptome of a Δcre-1 strain compared to wild type when grown on Avicel versus minimal medium (MM). more...

(Submitter supplied) Hemicellulose, the second most abundant plant biomass fraction after cellulose, is widely viewed as a potential feedstock for the production of liquid fuels and other value-added materials. Degradation of hemicellulose by filamentous fungi requires production of many different enzymes, which are induced by biopolymers or its derivatives and regulated mainly at the transcriptional level through transcription factors (TFs). more...

(Submitter supplied) Fungal degradation of lignocellulosic biomass requires various (hemi-)cellulases and plays key roles in biological carbon cycle. Although cellulases induction recently described in some saprobic filamentous fungi, regulation of cellulase transcription has not been studied thoroughly.

(Submitter supplied) Purpose: To explore the function of VIB1 in regulating cellulase production in Neurospora crassa. Method: mRNA from vib-1 mutants were collected after a culture shift from sucrose to Avicel (crystaline cellulose) or carbon-free media. Expression profiles of vib-1 mutants were compared with published profiles of wild type created under the same conditions. Results: We found that many genes that specifically upregulated in wild type upon exposure to Avicel were expressed at low levels in ∆vib-1 and many other genes involved in metabolism and energy were expressed at high levels compared to wild type. more...

(Submitter supplied) Identifying nutrients available in the environment and utilizing them in the most efficient manner is a challenge common to all organisms. The model filamentous fungus Neurospora crassa is capable of utilizing a variety of carbohydrates, from simple sugars to the complex carbohydrates found in plant cell walls. The zinc binuclear cluster transcription factor CLR-1 is necessary for utilization of cellulose, a major, recalcitrant component of the plant cell wall; however, expression of clr-1 in the absence of an inducer is not sufficient to induce cellulase gene expression. more...

Here, we discovered a novel membrane protein, CLP1 (NCU05853), a putative cellodextrin transporter-like protein, that is a critical component of the cellulase induction pathway in N. crassa. Although CLP1 protein cannot transport cellodextrin, the suppression of cellulase induction by this protein was discovered on both cellobiose and Avicel. more...

(Submitter supplied) abstract: The plant cell wall is composed of many complex polymers, and its deconstruction requires an equally complex orchestration of a wide array of enzymes. In Neurospora crassa, clr-1, clr-2 and xlr-1 have been identified as the key transcription factors involved in cell wall breakdown. In order to define their regulons, we performed ChIPseq upon these three transcription factors. CLR-1, CLR-2 and XLR-1 each bind to the most highly and differentially expressed gene populations, which include the cellulases for the CLRs and the hemicellulases for XLR-1. more...

(Submitter supplied) Sterol Regulatory Element Binding Proteins (SREBPs) are conserved from yeast to mammalian cells and function in regulating sterol homeostasis. In fungi, the SREBP pathway has been implicated in the adaptation to hypoxia and in virulence. In Neurospora crassa and Trichoderma reesei, the SREBP pathway also negatively regulates protein secretion under lignocellulolytic conditions. Here we utilized global transcriptional profiling combined with genetic and physiological analyses to address the regulatory link between the SREBP pathway and protein secretion in N. more...
