【摘要】 细胞内部的信号转导系统是介导真菌诱导子等外界因子诱发植物次生代谢产物合成的桥梁和纽带。一氧化氮(NO)是近年来发现的一种新型植物信号分子。近年来的研究表明,一氧化氮(NO)、水杨酸(SA)、茉莉酸(JA)、活性氧(ROS)等植物体内的主要信号分子(途径)不仅参与植物细胞次生代谢的信号调控,而且不同信号途径之间可以通过共催化、互抑制、共协调等作用相互交叉形成复杂的信号调控网络。本文简要介绍了国内外有关研究进展,重点结合本实验室的研究结果提出了以NO为关键节点的植物细胞次生代谢产物合成信号调控网络模型,提示了NO在植物细胞次生代谢信号调控网络中的潜在分子开关作用。更多还原

【Abstract】 The endogenous signaling network of plants plays important roles in mediating the exogenous factor-induced biosynthesis of secondary metabolites.Nitric oxide(NO) has emerged as a key signaling molecular in plants recently.Numerous studies demonstrated that the main signaling molecules such as NO, salicylic acid(SA),jasmonic acid(JA),and reactive oxygen species(ROS) not only were involved in regulating plant secondary metabolite biosynthesis but also interacted to form a complex signaling network by mutual inhibition and/or synergy.The recent progress in the signal network of plant secondary metabolite biosynthesis has been discussed in this paper.Futhermore,we propose a model to show that NO might act as a potential molecular switch in the signaling network leading to plant secondary metabolite biosynthesis.更多还原
