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:The protein kinase Ime2 is known to have an important role in meiosis in the yeast Saccharomyces cerevisiae. However, the Neurospora crassa IME2 homolog functions in self/nonself recognition as well as in the development of fungal sexual structures called protoperithecia. In N. crassa, protoperithecia are induced upon nitrogen starvation. We were interested in gene expression differences between an ime-2 deletion strain and a wild type strain, and due to the role of ime-2 during sexual development, carried out these arrays on media that was lacking in nitrogen.

Project description:A colony of fungus is comprised of long, branching filamentous cells called hyphae. Genetic mechanisms underlying the development of hyphae are poorly understood. We sectioned hyphae of a model fungus, Neurospora crassa (pink bread mold), into six parts depending on the age of the cells; 1 hour, 3 hour, 9 hour, 15 hour, 21 hour and 27 hour old, respectively. This data submission reflects an RNAseq analysis of mRNA extracted from the 1 hour time-point. 1 mycelial mRNA profile of 1 hour growth (hyphal tip) from Neurospora crassa strain FGSC 2489, Data was generated using Illumina GAIIx.

Project description:Multi-targeting priming (MTP) for genome-wide gene expression assays provides selective targeting of multiple sequences and counter-selection against undesirable sequences. We demonstrated superior performance of two MTPs compared to oligo-dT microarray profling and RNA tag sequencing the response of Saccharomyces cerevisiae to nitrogen deficiency and profiling Neurospora crassa early sexual development. Priming with MTPs in addition to oligo-dT resulted in higher sensitivity, a greater number of well-measured genes, more genes significantly differentially expressed, and a greater power to detect meager differences.

Project description: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. We therefore investigated whether light also regulates transcriptional regulation of cellulolytic enzymes in N. crassa. We show that the N. crassa photoreceptor genes wc-1, wc-2 and vvd are involved in regulation of cellulase gene expression, indicating that this phenomenon is conserved among filamentous fungi. Genome wide analysis of photoreceptor mutants and evaluation of results by analysis of mutant strains identified several candidate genes likely to play a role in light modulated cellulase gene expression. Three deletion strains (delta-wc-1 (FGSC 11712), delta-wc-2 (FGSC 11124) and delta-vvd (FGSC 11556)) and the wild type strain (FGSC 2489) at two different timepoints (28h or 40h) were analyzed. Cy3 and Cy5 dye swaps were performed.

Project description: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). Our data provide comprehensive information on the CRE-1 regulon in N. crassa and contribute to deciphering the global role of carbon catabolite repression in filamentous ascomycete fungi during plant cell wall deconstruction.

Project description:Neurospora tetrasperma is a pseudohomothallic filamentous ascomycete with a large (~ 7 Mbp) region of suppressed recombination surrounding its mating-type (mat) locus. The suppressed recombination has lead to sequence divergence between the two mating-type chromosomes of wild-type heterokaryotic strains, while the remaining genome is largely homoallelic. In this study, we use microarray technology to manifest expression divergence linked to mating type in N. tetrasperma. N. tetrasperma and N. crassa, were grown on agar regimes inducing sexual growth (Synthetic Crossing medium) and vegetative growth (Vogel's Medium), respectively.
