Mykorrhizaverkot

Mykorrhizaverkot, a term originating from German, literally translates to "mycorrhizal networks." These are vast underground systems formed by the symbiotic association between fungi and plant roots. The fungi, through their intricate network of hyphae (thread-like structures), extend far beyond the reach of individual plant roots, effectively increasing the surface area for nutrient and water absorption. In return, the plants provide the fungi with carbohydrates produced during photosynthesis.

These networks are crucial for forest ecosystems and other plant communities. They facilitate the exchange of nutrients like phosphorus and nitrogen between plants, and can even transfer carbon and defense signals. Older, established trees can act as "mother trees," supplying nutrients to younger seedlings through the mycorrhizal network, a phenomenon sometimes referred to as the "wood wide web."

The type of mycorrhizal association can vary, with the two most common being ectomycorrhizae and arbuscular mycorrhizae. Ectomycorrhizal fungi form a sheath around the root tips and penetrate the spaces between root cells, commonly found with trees like pines and oaks. Arbuscular mycorrhizal fungi, on the other hand, penetrate directly into the root cells, forming branched structures called arbuscules, and are widespread in grasses, crops, and many other herbaceous plants. The health and extent of these underground networks are vital indicators of the overall health of an ecosystem.
