Project description:In order to explore the stress-resistance related genes that may be regulated by upf1 in Neurospora crassa, we conducted RNA-seq experiments with upf1 knockout/WT strains treated with or without 20mM H2O2, and obtained gene expression data.

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:Many fungi form complex three-dimensional fruiting bodies, within which the meiotic machinery for sexual spore production has been considered to be largely conserved over evolutionary time. Indeed, much of what we know about meiosis in plant and animal taxa has been deeply informed by studies of meiosis in Saccharomyces and Neurospora. Nevertheless, the genetic basis of fruiting body development and its regulation in relation to meiosis in fungi is barely known, even within the best studied multicellular fungal model Neurospora crassa. We characterized morphological development and genome-wide transcriptomics in the closely related species Neurospora crassa, Neurospora tetrasperma, and Neurospora discreta, across eight stages of sexual development. Despite diverse life histories within the genus, all three species produce vase-shaped perithecia. Transcriptome sequencing provided gene expression levels of 2479 orthologous genes among all three species. Expression of key meiosis genes and sporulation genes, corresponded to developmental differences among these Neurospora species during sexual development. Screening N. crassa knockout crosses of genes selected for their expression differences across species, eight genes, whose functions were previously unknown, are found to be critical for the successful formation of perithecia. The absence of these genes in mutant crosses resulted in either no perithecium formation or in arrested development at an early stage. Our results provide insight into the genetic basis of Neurospora sexual reproduction, which is also of great importance with regard to other multicelluar ascomycetes, including fungal pathogens closely related to Neurospora in the Sordariomycetes, such as Fusarium spp, Magnaporthe oryzae, and Nectria haematococca mRNA were sampled and compared from eight time points across sexual reproduction in three Neurospora species

Project description:Cryptochromes were identified in plants and animals where they function as either photoreceptors or circadian clock components. In the filamentous fungus Neurospora, the biological function of cryptochrome has not yet been explored. Here, we demonstrate that Neurospora crassa cryptochrome (Nc cry) is a DASH-type of cryptochrome, capable of binding FAD and MTHF, whose transcript and protein levels are both strongly induced by blue light in a wc-1 dependent manner. Although the Nc cry transcript is circadian-regulated and antiphasic to frq, knockout strains of Nc cry appears to have a normal clock phenotype. Whole genome microarray and RT-QPCR analysis confirm that Nc cry is not involved in the signal transduction of either early or late light responses and seems to have no transcriptional regulatory activity under our laboratory conditions. Our study concludes that the only cryptochrome in Neurospora crassa is dispensable for the well-characterized blue light sensing cascade and is not part of the circadian clock system.

Keywords: light response Two-color microarray. Alexa Fluor 555 was consistently used to label cDNA synthesized from reference RNA, which is a mixture containing equal amounts of RNA samples harvested from different circadian time points and light treatment durations. The same batch of pooled RNA was used as a reference for each array experiment. Alexa Fluor 647 was used exclusively to label cDNA representing sample RNA.
