Most land plants rely on the symbiosis with arbuscular mycorrhizal (AM) fungi to acquire sufficient mineral nutrients from soils. Plants host AM fungi inside root cortex cells, where the fungus
forms highly branched structures called arbuscules. Arbuscules are surrounded by a specialized host membrane across which nutrients are exchanged in a cooperative manner. In return for
mineral nutrients, the fungus obtains sugars and fatty acids from the plant. Intriguingly, it has been shown that both plant and fungus can adjust the
amounts of nutrients exchanged depending on the benefits
that they obtain from their partner. This is thought to constitute a biological market that stabilizes the
symbiosis. The plant monitors its needs and the nutrients that it obtains and controls arbuscule development accordingly. Therefore, understanding the molecular basis of arbuscule
development and reciprocal nutrient exchange is of major importance for optimizing AM-plant benefits. |
