The Order Glomales is a group of fungi within the Phylum Glomeromycota that form arbuscular mycorrhizal (AM) associations with the roots of most terrestrial plants. These fungi are obligate symbionts, meaning they depend on their plant hosts for carbohydrates while providing the plants with essential nutrients like phosphorus and other minerals. Members of Glomales reproduce asexually through spores and are widespread in soils worldwide, playing a critical role in soil fertility, plant growth, and ecosystem stability. Their symbiotic relationships are especially important in agriculture and natural plant communities, enhancing nutrient uptake and improving resistance to environmental stress.
