The dikaryon formation (mating) transcriptome of the basidomycete fungus Coprinopsis cinerea (Coprinus cinereus)

ABSTRACT: Mating compatibility in C. cinerea is controlled by two loci, A and B. Following fusion of undifferentiated hyphal cells, a complex program is initiated which results in the maintenance of one nucleus from each parent in every cell (the dikaryon). We identified downstream targets of the A locus (A on), the B locus (B on), and both loci (Aon Bon) using strains in which the two pathways are activated separately, and a dikaryotic strain. keywords: Cell type comparison

Study of mating type genes and their roles in mating interactions of the basidiomycete Schizophyllum commune

Project description:Transcriptome changes associated with mating interactions were performed in order to identify signaling components and targets of pheromone response. Two monokaryons (S. commune 12-43 and 4-39), a dikaryon (W22 x 12-43), both semi-compatible mating interactions (Aon: W22 x 4-39; Bon, flat: W21 x 4-39), and different S. commune pheromone receptor recipient strains (Vbar2f, Vbar2t) were analyzed for that purpose. In addition, a S. commune strain showing the thin-phenotype (W22-thin) was investigated to figure out the role of Thn1 in mating. With microarray analysis mRNA expression in different mating interactions of the basidiomycete S. commune was analyzed. Genes which show regulation in the comparison of the two monokaryons 12-43 and 4-39 has been eliminated from other comparisons as strain specific differences. Two biological or technical replicate samples were analyzed for each condition.

Comparison of C. cinerea vegetative dikaryotic to vegetative monokaryotic mycelia

Project description:Coprinopsis cinerea vegetative dikaryotic mycelia compared to vegetative monokaryotic mycelia Vegetative dikaryon cDNA was comparitively hybridized with monokaryotic vegetative cDNA. Labelled cDNA was hybridized to arrays in a 2 channel reaction.

Smelling the difference: Transcriptome, proteome and volatilome changes after mating

Project description:Mushrooms, such as Schizophyllum commune, have a specific odor. Whether this is linked to mating, prerequisite for mushroom formation, or also found in monokaryotic, unmated strains, was investigated with a comprehensive study on the transcriptome and proteome of this model organism. Mating interactions were investigated using a complete, cytosolic proteome map for unmated, monokaryotic, as well as for mated, dikaryotic mycelia. The regulations of the proteome were compared to transcriptional changes upon mating and to changes in smell by volatilome studies. We could show a good overlap between proteome and transcriptome data, but extensive posttranslational regulation was identified for more than 80 % of transcripts. This suggests down-stream regulation upon interaction of mating partners and formation of the dikaryon that is competent to form fruiting bodies. The volatilome was shown to respond to mating by a broader spectrum of volatiles and increased emission of the mushroom smell molecules 3-octanone and 1-octen-3-ol, as well as ethanol and ß-bisabolol in the dikaryon. Putatively involved biosynthetic proteins like alcohol dehydrogenases, Ppo-like oxygenases, or sesquiterpene synthases showed correlating transcriptional regulation depending on either mono- or dikaryotic stages.

Gene expression analysis of monokaryotic and dikaryotic mycelia from Coprinopsis cinerea

Project description:Sexual reproduction is an ancient trait that evolved shortly after the appearance of the first eukaryotic cell. In order to identify the set of genes differentially expressed in monokaryotic and dikaryotic mycelia, the poly(A)-positive transcriptomes of C. cinerea Okayama7 and C. cinerea A43mutB43mut were sequenced.

The meiotic transcriptome of the basidomycete fungus Coprinopsis cinerea (Coprinus cinereus)

Project description:Coprinopsis cinerea exhibits synchronised meiosis in the gill tissue of the fungus, which is 75% meiotic. The mushroom develops from a dikaryon, which contains two separate nuclei. These nucleifuse in the basidia (karyogamy). After karyogamy, the nuclei enter an extended meiotic prophase, in which pahcytene occurs at 6 hours post karyogamy (K+6). The tetrads produced by the second meiotic division are present 12 hours after karyogamy (K+12). To examine a comprehensive timecourse of meiosis in this organism, we took samples over a 15-hour period, 3 hours apart: K-3, K, K+3, K+6, K+9, K+12. Keywords: time course

Gene expression analysis of stage 1 primordia and vegetative mycelia from Coprinopsis cinerea

Project description:Sexual reproduction is an ancient trait that evolved shortly after the appearance of the first eukaryotic cell. In order to study the transcriptional circuitries driving sexual reproduction in basidiomycota, we sequenced the poly(A)-positive transcriptome of stage 1 primordia and vegetative mycelia from the self-compatible dikaryotic basidiomycete Coprinopsis cinerea A43mutB43mut. Please note Okayama7 samples not included in this submission.
