Bioinformatic analysis of the transcriptome of mycorrhizal fungi Tuber melanosporum and Glomus intraradices

15 Dec 2011

Mycorrhizal symbiosis is a mutualistic interaction involving roots of terrestrial plants and soil fungi. Morphological changes associated with the development of this symbiosis are accompanied by changes in gene expression. The study of transcriptomic profiles is thus essential to characterize the molecular mechanisms that govern the mycorrhizal symbiosis. The recent development of high-throughput transcriptomic approaches provides new insights for the understanding of these mechanisms. The work undertaken during this thesis aimed to characterize in silico the transcriptome of the ectomycorrhizal fungus Tuber melanosporum and the endomycorrhizal fungus Glomus intraradices. In order to characterize transcripts expressed by the symbionts and to identify genes regulated during symbiosis, bioinformatic tools and protocols were implemented to process transcriptomic data derived from new sequencing technologies. This work has allowed to highlight common features in the expression profiles of mycorrhizal fungi. In addition, characterization of the G. intraradices transcriptome has allowed to establish the first genome-wide repertoire of genes for an endomycorrhizal fungus. The study helps to improve knowledge about the molecular processes underlying the mycorrhizal symbiosis and provides a unique resource for future research on the gene networks controlling symbiosis
