Archaeosporaceae fungi

The Archaeosporaceae family belongs to a group of beneficial soil fungi known as arbuscular mycorrhizal fungi (AMF). They are not plant pathogens, but rather essential symbionts that foster healthy plant growth by establishing a mutualistic relationship with the roots of the vast majority of agricultural crops.

The biological mechanism behind this symbiosis involves the fungus extending its hyphae into the soil, acting as a secondary root system. Within the plant root cells, the fungi develop branched structures called arbuscules, where they exchange phosphate, nitrogen, and micronutrients absorbed from the soil for carbohydrates synthesized by the plant.

Practically all major crops, including cereals, legumes, and horticultural plants, form associations with Archaeosporaceae. This connection is particularly vital in environments where nutrients are limited or soil physical properties are suboptimal, as the fungus provides the plant with essential resources that the roots alone cannot reach.

Environmental conditions for these fungi require a healthy, undisturbed soil ecosystem. Excessive chemical application, heavy tillage, and monocropping without plant cover can disrupt the delicate mycorrhizal network. Maintaining soil biodiversity is essential to support these fungi and ensure the long-term sustainability of the field.

From an agronomical standpoint, promoting these fungal populations offers significant economic benefits. By enhancing plant resilience against drought and nutrient deficiency, Archaeosporaceae help stabilize yields and improve the overall biological quality of the farmland.

• Enhanced phosphorus uptake in crops.
• Improved plant tolerance to drought and salinity.
• Increased root system surface area.
• Long-term improvement of soil structure through glomalin production.
