摘 要:来源于真菌或植物细胞壁的激发子可以诱导植物的抗性反应。 一系列的信号分子,如一氧化氮、活性氧、茉莉酸、水杨酸、乙烯等都参与了激发子诱导的植物抗性反应。它们在介导激发子刺激诱发胞内抗性反应的过程中起着重要的作用。本文介绍了激发子的种类,并简述了激发子受体以及植物细胞对激发子刺激的感受与传递;重点介绍了一氧化氮在激发子诱导植物抗性反应过程中的作用,以及它与其他信号分子之间相互关系的研究进展。
关键词:一氧化氮;激发子;植物抗性;信号转导

Abstract: Elicitors, derived from cell wall of fungi or plants, can induce a line of defense responses in plants. During these processes, a multiple of plant signal molecules, such as nitric oxide, reactive oxygen species (ROS), jasmonic acid, salicylic acid, ethylene etc., play the essential role in conveying the elicitor stimulation to intracellular defenses responses. In this review, at first we described the classification of elicitors, and introduced briefly the receptor, conveying and responses of plant cell to elicitor stimulation. At last we focused on the detailed role and new research proceeding of nitric oxide involving elicitor-induced defense responses, and its interaction with other plant signal molecules.
Key words: nitric oxide; elicitor; plant defense; signal transduction
