Mycorrhizal symbioses influence the trophic structure of the Serengeti — Bo Maxwell Stevens — Journal of Ecology
More than 80 % of all land plants live in so - called arbuscular
mycorrhizal symbioses with fungi that colonize their root systems.
«However, recent work has shown that at least some of the fungal partners in arbuscular
mycorrhizal symbioses lack the genes for enzymes involved in the major pathway of lipid biosynthesis, and are therefore unable to produce certain essential fatty acids,» Gutjahr explains.

Arbuscular
mycorrhizal (AM)
symbiosis is the interaction between plants and a group of fungi called Glomeromycota.
The team also found that up to 40 percent of the
symbiosis - induced genes were restricted to a single
mycorrhizal species.
«The other major part of the story is that in
mycorrhizal lineages there is a huge turnover in genes that are upregulated in the
symbiosis - many of these have no homologs in even closely related species, suggesting that the evolution of the
symbiosis is associated with massive genetic innovation.»
In the traditional view of this
symbiosis, the plants photosynthesize and provide carbon to the fungi in return for nutrients that the fungi take up from the soil (I say traditional because
mycorrhizal fungi can also provide other benefits to their hosts such as helping them deal with summer water stress and protecting them from pathogens that attack their roots).
