Arbuscular mycorrhizal fungi (AMF) are symbiotic soil fungi which colonize roots of about 80% of
vascular plants. The mycorrhizal symbiosis enhances the growth and survival of numerous plant species.
The complex cellular relationship between the host roots and AMF requires a continuous exchange of
signals, which in return affects the regulation of genes whose products participate in metabolic and
structural changes that lead to the symbiosis.
