Origins of the mycorrhizal symbioses
Christine Strullu-Derrien , Paul Kenrick , Marc-Andre Selosse
AbstractSymbioses encompass a wide variety of organismal associations in diverse environments, including: bacteria and fungi that form close alliances with the roots of plants; dinoflagellates that live within the endoderm of tropical corals; bacteria that sustain giant tube worms in the deep ocean. This chapter presents a brief review of current knowledge of the fossil record of mycorrhizas in the context of plant evolution. It identifies areas in which the fossil record (palaeomycology) can be of relevance to genomics, and recommends an approach that would bridge the two disciplines. The most common associations are the arbuscular mycorrhiza (AM) symbioses, in which fungi are all members of the phylum Glomeromycota, which form a single and ancient clade. Arborescence is known to have evolved independently in many different groups, and a variety of biomechanical strategies were employed. Ectomycorrhizal symbioses evolved from ecologically diverse decayer precursors and radiated in parallel, following the origins of their host-plant lineages.
