Project description:We investigated the ascomycete truffle Tuber melanosporum exploits DNA methylation and transcription to cope with the more than 45,000 repeated elements that are present in its genome. Whole-genome bisulfite sequencing and RNA-sequencing, were performed on different developmental stages of this symbiotic hypogeous fungus -fruitbody (FB), free-living mycelium (FLM), and ectomycorrhiza.

Examination of DNA methylation and transcription of truffle in its free living mycelium (FLM), fruit body (FB), and ectomycorrhizal root tips (ECM)
Project description:The Transcriptome of different tissues and developmental stages of Tuber melanosporum was analyzed. The array probes were designed from gene models taken from the French Genoscope - Centre National de Séquençage Tuber melanosporum genome sequence version 1. One aim of this study was to verify the expression of the automatically annotated gene models in various tissues and to use this transcriptional information to confirm, to correct or to reject gene models. Another goal was to identify tissue-specific gene expression, e.g. mycorrhiza up-regulated transcripts or fruiting body up-regulated transcripts for further detailed analyses.
Project description:This study characterizes the transcriptomic alterations of Tuber melanosporum during fruiting body development. Stage III, IV, V and VI were analyzed. For images and description of stages see Zarivi et al.2015 (https://doi.org/10.1016/j.phytochem.2015.02.024)
Project description:The aim of this analysis was to better understand the complex symbiotic stage of Tuber melanosporum by combining the use of laser capture microdissection and microarray gene expression analysis. We isolated the fungal/soil (i.e. the mantle) and the fungal/plant (i.e. the Hartig net) interfaces from transverse sections of T. melanosporum/Corylus avellana ectomycorrhizas and identified the transcriptional landscape associated with each compartment. We compared these data to the transcriptome of ectomycorrhizal root tips, free-living mycelium and fruiting bodies of Tuber melanosporum (Series GSE17529).
