| Research Abstract |
This study focused on the role of coumarins in plants. Visualization of the key enzyme of coumarin biosynthesis showed spacial detail of its biosynthesis. After infectious stimulation by fungus or elicitors, local induction of coumarin biosynthesis was found around the area of infection.
Coumarin degradation in the rhizosphere of Prunus sp. was detected, where coumarin-degrading microbes were isolated. The coumarin degrading microbes were isolated from soil only around Prunus tree. This result indicates the interaction between the plant and the microbe by coumarin.
Coumarin degradation pathway by these microbes were determined. The intermediates of degradation showed no activity to other microbes and plants.
