Root Symbiosis Is Regulated Through Nutrient Status of Plants

Land plants absorb phosphate better when they collaborate with certain soil fungi. Arbuscular mycorrhiza (AM), a symbiosis with such fungi, is used by more than 80 percent of plants. The fungi penetrate the root cortex cells and form hyphal networks in the soil.
These take up phosphate from the soil and transport it directly into the root, where it is released into the root cells via tree-shaped fungal structures called arbuscules.
