(Kobe University) A research team led by Kobe University's Associate Professor SUETSUGU Kenji (of the Graduate School of Science's Department of Biology) has investigated the carbon age in some non-photosynthetic mycoheterotrophic plants. Using the radiocarbon emitted from atmospheric nuclear bomb tests carried out in the 1950s and 1960s as a tracer, they revealed that some mycoheterotrophic orchids are relying on 14C-enriched bomb carbon from dead wood via saprotrophic fungi.
