The 450-million-year-old symbiosis between the majority of land plants and arbuscular mycorrhizal (AM) fungi is one of the most ancient, abundant, and ecologically important symbioses on earth (Remy et al. 1994; Taylor et al. 1995). The obligate biotrophic nature of the AM fungus makes it difficult to study and analyze the fungus in vitro (absence of roots), but it is conceivable that the early events in the evolution of mycorrhizal symbioses may have involved reciprocal genetic changes in ancestral plants and free-living fungi. The prospect makes this system a remarkably interesting one to characterize and fully understand.
