| Outline of Final Research Achievements |
We developed new methods to resolve three central issues concerning efficient ex situ conservation of mycoheterotrophic plants, i. e., 1) isolation of particular fungi in association with the host plant species, 2) culture and preservation of isolated fungi, and 3) establishment of plant-fungi symbiosis. Regarding the first issue, mass isolation of target fungal species was accomplished by repeated washes of hyphae in aqueous solution of antibiotics. In relation to the second issue, covering of hyphae with humus from the habitat of target species facilitated the growth and subsequent formation of fruit bodies. On the last issue, mycoheterotrophic plant-fungi symbiosis was established in this study, while further experiments are needed to establish tripartite symbiosis involving an autotrophic plant, a fungus, and a mycoheterotrophic plant.
