In order to determine the existence and relevance of common mycorrhizal networks in nature, what evidence is required?
escribe the similarities between the establishment of arbuscular mycorrhizae and legume root nodules. Which is considered to be older evolutionarily? What is the evidence for this?
Ecologists often attempt to introduce new plants to restore degraded land. In an arid climate, scientists recommend introducing plants with arbuscular mycorrhizae. How would the mycorrhizae increase the plants’ survival compared to plants without mycorrhizae?
