| 摘 要： | 拟南芥是研究植物与病原物相互作用的模式植物。植物感病和抗病取决于病原物无毒基因产物和寄主抗病基因产物的识别,以及随后的相关防卫反应的激活。在拟南芥的抗病过程中,水杨酸、茉莉酸、乙烯等信号分子都不同程度地参与着抗病过程中的不同环节,起着非常重要的作用。由于这些信号分子在对不同病原菌的抗性中的作用存在差异,因而将抗病信号传导分为依赖于水杨酸和依赖于茉莉酸/乙烯的途径。本文将着重讨论这些信号分子在植物系统获得抗性以及诱导系统抗性中的作用。

| Abstract: | Arabidopsis thaliana is a model plant to study the interplays between plants and pathogens. Plants exhibiting re-sistance or causing disease follow the hypothesis of "gene for gene", in which only when the products from the avirulencegene of pathogen and the resistance gene of host recognize each other, can plants arise a series of defense responses andshow resistance, otherwise plants develop diseases. Small molecules such as salicylic acid, jasmonic acid, ethylene playimportant roles in the defense responses, and the signal transduction pathways can be divided according to their effects in aparticular system of the pathogen and plant interactions. Their roles in systemic acquired resistance and induced systemic re-sistance will be discussed in detail. |
