New inhibitor for the functional analysis of tryptophan metabolism in plants

水稻植物在病原体攻击时会从色氨酸中产生血清素。5-羟色胺合成抑制剂的处理导致了敏感性的增强，表明5-羟色胺的产生在水稻的防御反应中的重要性。另外，我们还发现水稻褐斑病的致病因子小离蠕孢菌（Bipolaris）能将5-羟色胺降解为相应的羧酸。在此基础上，我们可以解释水稻和B之间的化学战。- 是的

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.
