Although it goes beyond the rhizosphere area, it is to note that some plants secrete garlic mustard produces a chemical which is believed to prevent mutualisms forming between the trees and mycorhiza in mesic North American temperate forests.[5]

Plants rice plant exhibit diurnal cycles that mimic plant behavior, and tend to supply more fixed nitrogen during growth stages when the plant exhibits a high demand for nitrogen.[4]
