Exploring the Genome of glomeromycotan fungi

Chapitre 1; International audience; All fungi forming a mutualistic symbiosis with plant roots called arbuscular mycorrhiza were formerly grouped together in one order, the Glomales, placed in the Zygomycota (Morton 1993). Based on molecular analyses suggestingthat arbuscular mycorrhizal fungi should be separated from other fungal taxa, they were transferred a decade ago to the Glomeromy-cota , a new phylum created specifically for them (Schu¨ ssler et al. 2001). Whilst members of this monophyletic group originated from the same common ancestor as the Ascomycota and Basidiomycota, they have no obvious affinity to other major extant phylogenetic groups in the kingdom Fungi (James et al. 2006) …
