| Research Abstract |
We tested evolution of ecophysiological characters associated with the acquisition of mycoheterotrophy in several orchid groups. We demonstrated the following insights : 1) in several orchid groups, full mycoheterotrophy appeared gradually via partial mycoheterotrophy, not directly from autotrophy. 2) Mycoheterotrophy is results of evolution of various characters related to ecophysiological properties. 3) Each mycoheterotrophic species exhibits different combinations of characters relevant to nutrition. The processes involved in shifting from autotrophy to mycoheterotrophy are diverse and complex, whereas previous studies emphasized a simple evolutionary event.
