Cryopreservation of orchid mycorrhizal fungi: A tool for the conservation of endangered species

The effectiveness of cryopreservation at − 80 °C on orchid mycorrhizal fungi was assessed by testing the symbiotic ability of ten fungal isolates following cryo-storage for 10–24 months. The results obtained prove the efficacy of the method, thus providing a valuable tool for ex situ conservation.
