Market Theory: Trading Between Uneven Partners
Approximately 80 % of all known land plant species form mycorrhizal interactions. This interaction is generally considered to be a mutualistic association, where plant-produced carbon (C) is exchanged for mycorrhizal fungi acquired soil nutrients. Most of mycorrhizal fungi are not host specific and an individual fungi can colonize simultaneously a large number of plants, of same or different species, leading to plants to become interconnected by the mycorrhizal fungi, forming the so-called common mycorrhiza network (CMN). Several studies have been proposed to demonstrate the potential effects of the CMN networks mediating resource partitioning and thus plant fitness, however there are still several issues that remains controversial about the subject, especially regarding autotrophic plants.
