What are arbuscular mycorrhizae?
Quick Answer
Arbuscular mycorrhizae are fungal partnerships where the fungus enters root cells and forms tiny tree-like structures. They are among the oldest and most widespread plant-fungus symbioses.
The Full Story
In arbuscular mycorrhizae, fungi penetrate the cortex of plant roots and form branching structures called arbuscules inside the cells. These arbuscules are the main sites where nutrients are exchanged between fungus and plant. This relationship is ancient and is found in most land plants, including many crops and wildflowers. It helps plants access phosphorus, one of the most limiting nutrients in many soils.
Key Facts
1.Arbuscules are tiny branching exchange structures
2.Common in many crops and wild plants
3.Especially important for phosphorus uptake
