The Phylum Glomeromycota consists of fungi that form arbuscular mycorrhizal (AM) associations with the roots of most terrestrial plants. These fungi are obligate symbionts, providing plants with nutrients like phosphorus in exchange for carbohydrates. They reproduce asexually through spores and are crucial for soil health, plant growth, and ecosystem stability. Glomeromycota are widespread and play a key role in supporting agriculture and natural plant communities.
