Neurospora crassa early sexual development with oligod(T) priming

ABSTRACT: 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. Neurospora crassa mat A FGSC#2489 2 developmental stages and oligo(dT) primers.

<h4>Background</h4>Complementary approaches to assaying global gene expression are needed to assess gene expression in regions that are poorly assayed by current methodologies. A key component of nearly all gene expression assays is the reverse transcription of transcribed sequences that has traditionally been performed by priming the poly-A tails on many of the transcribed genes in eukaryotes with oligo-dT, or by priming RNA indiscriminately with random hexamers. We designed an algorithm to fin ...[more]

Saccharomyces cerevisiae grown in nitrogen depletion with oligodT priming

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. Saccharomyces cerevisiae S288c was grown on two different media and two different primers were used for reverse transcription: oligo(dT) and Multi-Targeted Primer [MTP] protoperithecia oligo(dT)+ MTP (PP2) perithecia oligo(dT)+ MTP (PT2).

Mating-type specific gene expression in the filamentous ascomycete Neurospora tetrasperma

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. [SC]: Neurospora tetrasperma mat-A FGSC#1270; mat-a FGSC#1271; Mat-A FGSC#9033; mat-a FGSC#9034; N. crassa mat-A FGSC#2489 and mat-a FGSC 4200: Synthetic Crossing medium was used as a nutrient regime before sampling and processing [Veg]: Neurospora tetrasperma mat-A FGSC#1270; mat-a FGSC#1271; Mat-A FGSC#9033; mat-a FGSC#9034; N. crassa mat-A FGSC#2489 and mat-a FGSC 4200: Vogel's Medium (Vegetative Medium) was used as a nutrient regime before sampling and processing

Characterization of Neurospora crassa ghh (NCU06095) mutant strains

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.
