Mycorrhizal Fungal Partners Remain Constant during a Root Lifecycle of <i>Pleione bulbocodioides</i> (Orchidaceae)

Mycorrhizal mutualisms are vital for orchids through germination to adulthood. Fungal species diversity and community composition vary across seasons and plant development stages and affect plant survival, adaptation, and community maintenance. Knowledge of the temporal turnover of mycorrhizal fungi...
