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.
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
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.
Project description: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
Project description:Intracellular signaling is conserved in eukaryotes to allow for response to extracellular signals and to regulate development and cellular functions. In fungi, inositol phosphate signaling has been shown to be involved in growth, sexual reproduction, and metabolic adaptation lacking, however, reports of mushroom forming fungi so far. In Schizophyllum commune, an inositol monophosphatase has been found up-regulated during sexual development. The enzyme is crucial for inositol cycling where it catalyzes the last step of inositol phosphate metabolism restoring the inositol pool from the monophosphorylated inositol monophosphate. We overexpressed the gene in this model basidiomycete and verified its involvement in cell wall integrity and intracellular trafficking. Strong phenotypes in mushroom formation and cell metabolism were evidenced by proteome analyses. In addition, altered inositol signaling was shown to be involved in tolerance towards cesium and zinc, and increased metal tolerance towards cadmium, associated with induced expression of kinases and repression of phosphatases within the inositol cycle. The presence of the heavy metals Sr, Cs, Cd, and Zn lowered intracellular calcium levels. We could develop a model integrating inositol signaling in the known signal transduction pathways governed by Ras, G-protein coupled receptors, cAMP and elucidate different roles in development.
