Research Abstract

Rice plants produce serotonin from tryptophan in response to pathogen attack. The treatment of the inhibitor of serotonin synthesis resulted in the enhanced susceptibility, indicating the significance of serotonin production in the defense responses of rice. In addition, we found that the casual agent of rice brown spot, Bipolaris oryzae, degraded serotonin to corresponding carboxylic acid. On the bases of these findings, we could illustrate the chemical battle between rice and B. oryzae.
