The genome of an organism bears the signature of its lifestyle, and organisms with similar life strategies are expected to share common genomic traits. Indeed, ectomycorrhizal and arbuscular mycorrhizal fungi share some genomic traits, such as the expansion of gene families encoding taxon-specific small secreted proteins, which are candidate effectors in the symbiosis,and a very small repertoire of plant cell wall-degrading enzymes. A large gene family coding for andidate effectors was also revealed in ascomycetous ericoid mycorrhizal (ERM) fungi, butthese fungal genomes are characterised by a very high number of genes encoding degradative enzymes,mainly acting on plant cell wall components. We suggest that the genomic signature of ERM fungi mirrors a versatile lifestrategy, which allows them to occupy several ecological niches. |
