| 摘 要： | 东莨菪内酯属香豆素类化合物,是烟草中重要的植物保卫素,能抗烟草花叶病、灰霉病、野火版、青枯病、黑胫病等多种病害,其在烟草组织中通过苯丙氨酸解氨酶(PAL)调控合成,当受到不良环境影响或者外源物质(茉莉酸甲酯、2,4-D、核黄素、细胞分裂素等)诱导时,东莨菪内酯在烟草葡萄糖基转移酶(TOGTs)调控转化为东莨菪苷转移到液泡中发挥抗病作用。该文综述了东莨菪内酯对烟草中的生物合成及诱导抗性的相关研究,以期为提高烟草的抗病性及防治提供理论依据。

| Abstract: | Scopoletin is a coumarin compound and an important member of the group of phytoalexins isolated from tobacco. Scopoletin has been correlated with resistance to TMV,tobacco grey mold,tobacco bacterial wilt,Pseudomonas tabaci,Phytophthora porasitica var. nicotianae etc. Scopoletin wis biosynthesized by phenylalanine ammonia lyase, and Accumulation of scopoletin has been correlated with resistance to microbial attack and induced by methyl jasmonate ,2,4-D ,riboflavin,cytokinin etc. Scopoletin has been transfered to scopolin by TOGTs in vacuole. The paper summarized research progress of phytoalexin scopoletin induced resistance in tobacco,in order to provide a theoretical reference for improving disease resistance and provention. |
