Project description:To identify proteins that localize to MCC/eisosomes in N. crassa, we isolated proteins that co-purified with the core MCC/eisosome protein LSP-1, which was tagged with GFP. Proteins that co-fractionated with LSP-1::GFP were then identified by mass spectrometry.

Project description:To determine the genes directly and indirectly under the control of the Grainy-head homolog (GHH) transcription factor in Neurospora crassa Three different sample types (Aerial Hyphae & Conidia; Mycelia; or Whole Colonies) of both wild-type (FGSC #2489) and grainy-head homolog (FGSC #13563) strains of Neurospora crassa were subjected to transcriptome analyses to determine the genes differentially expressed in the ghh background compared to wild type.

Project description:Transcriptional profiling with next-generation sequencing methods demonstrated that a Neurospora crassa mutant with the three most highly expressed beta-glucosidase genes deleted had a transcriptional response to cellobiose similair to that of wild type N. crassa exposed to cellulose. N. crassa was pregrown in Sucrose and transferred to Avicel (cellulose), Cellobiose, Sucrose or media with no carbon added. Biological triplicates used to identify differentially expressed genes in WT on Avicel. Single libraries for mutant strains identify which genes show similair expression on cellobiose as in the WT on cellulose.

Project description:Quantitative acetyl-proteomics, a newly identified post-translational modification, is known to regulate transcriptional activity in different organisms. Neurospora crassa is a model ascomycete fungus maintained for biochemistry and molecular biology research; however, extensive studies of the functions of its acylation proteins have yet to be performed. In this study, using LC-MS/MS qualitative proteomics strategies, we identified 1909 modification sites on 940 proteins in N. crassa and analysed the functions of these proteins using GO enrichment, KEGG pathway, and subcellular location experiments. We classified the acetylation protein involvement in diverse pathways, and protein-protein interaction (PPI) network analysis further demonstrated that these proteins participate in diverse biological processes. In summary, our study comprehensively profiles the crosstalk of modified sites, and PPI among these proteins may form a complex network with both similar and distinct regulatory mechanisms, providing improved understanding of their biological functions in N. crassa.

Project description:Histone H1 variants, known as linker histones, are essential chromatin components in higher eukaryotes, yet compared to the core histones relatively little is known about their in vivo functions. The filamentous fungus Neurospora crassa encodes a single H1 protein that is not essential for viability. To investigate the role of N. crassa H1, we constructed a functional FLAG-tagged H1 fusion protein and performed genomic and molecular analyses. Cell fractionation experiments showed that H1-FLAG is a chromatin binding protein. Chromatin-immunoprecipitation combined with sequencing (ChIP-seq) revealed that H1-3XFLAG is globally enriched throughout the genome with a subtle preference for promoters of expressed genes. In mammals, the stochiometery of H1 impacts nucleosome repeat length. To determine if H1 impacts nucleosome occupancy or nucleosome positioning in N. crassa, we performed micrococcal nuclease digestion in wildtype and the ∆hH1 strain followed by sequencing (MNase-Seq). Deletion of hH1 did not significantly impact nucleosome positioning or nucleosome occupancy. Analysis of DNA methylation using methylC-sequencing (mC-Seq) revealed a modest but global increase in DNA methylation in the ∆hH1 mutant. Together, these data suggest that H1 acts as a non-specific chromatin binding protein that can limit accessibility of the DNA methylation machinery in N. crassa.

Project description: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). Neurospora crassa has been shown to express and secrete plant cell wall associated enzymes. To better understand genes specifically associated with degradation of hemicellulose, we identified 353 genes by transcriptome analysis of N. crassa wild type strain grown on beechwood xylan. Exposure to xylan induces 9 of the 19 predicted hemicellulase genes. The xylanolytic phenotype of strains with deletions in genes identified from the secretome and transcriptome analysis of wild type showed that none were essential for growth on beechwood xylan. The transcription factor XlnR/Xyr1 in Aspergillus and Trichoderma species is considered to be the major transcriptional regulator of genes encoding both cellulases and hemicellulases. We identified a xlnR/xyr1 homolog in N. crassa, NCU06971, termed xlr-1 (xylanase regulator 1). Deletion of xlr-1 in N. crassa abolishes the growth on xylan and xylose, but growth on cellulose was indistinguishable from wild type. To determine regulatory mechanisms associated with hemicellulose degradation, we explored the transcriptional regulon of XLR-1 under xylose and xylanolytic versus cellulolytic conditions. XLR-1 regulated only some predicted hemicellulase genes in N. crassa and was required for a full induction of several cellulase genes. Hemicellulase gene expression was induced by a combination of release from carbon catabolite repression (CCR) and induction. However, in N. crassa, xlr-1 is subject to non-CRE-1 mediated CCR. This systematic analysis provides the similarities and differences of hemicellulose degradation and regulation mechanisms used by N. crassa in comparison to other filamentous fungi. Four-condition experiments (minimal medium, xylan medium,xylose and Avicel medium) of mutant strain(xlr-1) compared to wild type strain; Cy3 and Cy5 dye swap
