mycorrhizaal
Mycorrhizaal refers to a type of symbiotic association between fungi and plant roots. In a mycorrhizaal relationship, the fungal partner colonizes the plant’s root system, forming structures that extend the plant’s access to water and nutrients. In return, the plant provides the fungus with carbohydrates produced by photosynthesis.
Two major forms are ectomycorrhizal and arbuscular mycorrhizal. Ectomycorrhizal fungi envelop root tips with a dense
Other specialized forms include ericoid and orchid mycorrhizas, found in ericaceous plants and some tropical orchids,
Ecological and agricultural significance: these associations are highly prevalent in terrestrial ecosystems and affect plant productivity,
