ectotrophic mycorrhiza

biology
Also known as: ectomycorrhiza

Quick Summary

Ectotrophic mycorrhiza is a symbiotic association between a fungus and the roots of a plant, primarily seen in trees like pines. In this relationship, the fungus forms a sheath or mantle around the plant's smaller roots. This partnership is mutually beneficial: the fungus helps the plant absorb essential mineral nutrients, particularly phosphorus, from the soil. In return, the plant provides the fungus with carbohydrates and other nutrients produced through photosynthesis. This symbiotic relationship is crucial for the survival and flourishing of certain plant species and plays a significant role in forestry and horticulture.12
