What is Ectotrophic mycorrhiza?
/ (ˌɛktəʊˈtrɒfɪk) / noun. botany a type of mycorrhiza, typical of temperate and Boreal trees, in which the fungus forms a layer on the outside of the roots of the plantAlso called: ectomycorrhiza Compare endotrophic mycorrhiza.
What is endotrophic mycorrhiza?
endotrophic mycorrhiza A type of mycorrhiza in which the fungal component penetrates the plant root, either pathogenically or beneficially. The fungal component does not change the root morphology. Compare ECTOTROPHIC MYCORRHIZA.
What is the Ectotrophic mycorrhiza associated with Pinus roots are?
Ectotrophic mycorrhiza is found in temperate and Boreal trees, in which a layer of fungus is seen on the outside of the roots of the plant. Pinus radiata and Amanita muscaria are examples which show ectotrophic mycorrhiza. So, the correct option is ‘Pinus’.
Who discovered mycorrhiza?
Albert Bernhard Frank
This symbiosis was studied and described by Franciszek Kamieński in 1879–1882. Further research was carried out by Albert Bernhard Frank, who introduced the term mycorrhiza in 1885.

Where do Plasmogamy and Karyogamy occur?
Plasmogamy takes place between the ascogonium and antheridium through the trichogyne. Karyogamy takes place in the ascus.
What is VAM mycorrhiza?
Vesicular-arbuscular mycorrhiza (VAM) is formed by the symbiotic association between certain phycomycetous fungi and angiosperm roots. The fungus colonizes the root cortex forming a mycelial network and characteristic vesicles (bladder-like structures) and arbuscules (branched finger-like hyphae).
Where is ectomycorrhizae found?
Ectomycorrhizas form on the roots of around 2% of plant species, usually woody plants, including species from the birch, dipterocarp, myrtle, beech, willow, pine and rose families. Research on ectomycorrhizas is increasingly important in areas such as ecosystem management and restoration, forestry and agriculture.
What is mycorrhizal biotechnology?
Mycorrhiza are symbiotic associations between plant roots and certain soil fungi which play a key role in nutrient cycling in the ecosystem and also protect plants against environmental and cultural stress.
Can mycorrhizae be harmful to humans?
Mycorrhizae are not harmful to humans. Arbuscular mycorrhizal fungi are obligate partners, meaning that they require a plant host to germinate and…
