Mycorrhzial fungi are involved with a wide variety of other activities that benefit plant establishment and growth. The same extensive network of fungal filaments important to nutrient uptake is also important in water uptake and storage. In non-irrigated conditions, mycorrhizal plants are under far less drought stress compared to non-mycorrhizal plants.
Disease and pathogen suppression is another benefit for a mycorrhizal plant. Mycorrhizal fungi actually attack pathogens or disease organisms entering the root zone the fungi. For example, excretions of specific antibiotics produced by mycorrhizal fungi immobilize and kill disease organisms. Some mycorrhizal fungi protect plants and trees from Phytophora, Fusarium and Rhizoctonia diseases. In addition mycorrhizal roots contain a mantle (a tight, interwoven socklike covering of dense filaments) that acts as a physical barrier against the invasion of root diseases.
Mycorrhizal fungi also improve soil structure. Mycorrhizal filaments produce humic compounds and organic "glues" (extracellular polysaccharides) that bind soils into aggregates and improves soil porosity. Soil porosity and soil structure positively influence the growth of plants by promoting aeration, water movement into soil, root growth, and distribution. In sandy or compacted soils the ability of mycorrhizal fungi to promote soil structure may be more important than the seeking out of nutrients.
