Mycology
Arbuscular
Describing a type of mycorrhizal fungus that forms tree-like branching structures (arbuscules) inside plant root cells. Arbuscular mycorrhizae are the most common plant-fungus symbiosis.
Biological Context
Arbuscular mycorrhizal fungi penetrate root cell walls and form arbuscules—intricate branching structures that maximize surface area for nutrient exchange. The fungus provides phosphorus and other minerals; the plant provides sugars. This symbiosis predates roots themselves, helping plants colonize land.
Business Application
Arbuscular partnerships penetrate organizational boundaries to create intimate exchange relationships. Joint ventures, embedded teams, and co-located employees create arbuscule-like structures that maximize information and resource exchange between partners.
