Effect of sc3 and sc4 on aerial hypha formation

ABSTRACT: In order to study changes in gene expression during mushroom development in Schizophyllum commune, genome wide gene expression was analysed in 4 developmental stages: vegetative mycelium, stage I aggregates, stage II primordia and mature mushrooms. In order to study the effects of absence of expression of sc3 and sc4, genome-wide expression was analysed in a dikaryon in which those genes have been inactivated by targeted gene deletion.

Genome-wide expression analysis of dikaryotic colonies of Schizophyllum commune: wild-type, delta-hom2, delta-fst4

Project description:The transcription factors Hom2 and Fst4 were shown to be involved in mushroom development in the basidiomycete Schizophyllum commune. When the genes encoding Hom2 or Fst4 were deleted, no mushrooms formed. In this study we performed a genome-wide expression analysis on dikaryons of wild-type, delta-hom2 and delta-fst4.

Effect of light on gene expression in Schizophyllum commune

Project description:In order to study the effect of light on gene expression in Schizophyllum commune, genome wide gene expression was analysed in 4-day-old monokaryotic and dikaryotic wild type colonies, grown either in light or in darkness. 4 samples: - monokaryon, grown for 4 days in the light - monokaryon, grown for 4 days in the dark - dikaryon, grown for 4 days in the light - dikaryon, grown for 4 days in the dark RNA was obtained from 3 biological replicates and pooled

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.

Genome-wide expression analysis of dikaryotic colonies of Schizophyllum commune under various conditions: wild-type, delta-wc2, delta-wc2 hsp3(pr)-wc2

Project description:The blue light receptor WC-2 was shown to be involved in mushroom development in the basidiomycete Schizophyllum commune. When the gene encoding WC-2 was deleted, no mushrooms formed and colony morphology was radial. This phenotype was similar to the wild-type colony grown in the dark. This phenotype could be complemented by transforming the wc-2 deletion strain with a construct encompassing the wc-2 coding sequence under the control of the heat inducible promoter hsp3. A daily heat shock of 1 hour at 42 degrees Celsius resulted in mushroom development and an asymmetrical colony. In this study we performed a genome-wide expression analysis on dikaryons of wild-type (not heat shocked), delta-wc2 (heat shocked or not heat shocked) and the complemented strain delta-wc2 hsp3-wc2 (heat shocked or not heat shocked).
