Definition of Mycorrhizae
Mycorrhizae is the symbiotic relationship between plants and fungi. Mycorrhizal association deals with the interaction of fungi with the root system of the plants. They play a significant role in soil chemistry, soil biology, and the nutrition of the plants. The interaction does not harmfully infect the roots of the plants.
The fungus invades the roots just intending to absorb the nutrients which are required for its normal growth and survival. The plants are depending upon the fungus for mineral nutrients like phosphorus. In this way, both are getting benefits from each other.
