摘　　要：植物受到病原菌侵染时会发生一系列防卫反应:通过各种信号反应事件,如抗病信号的产生、传导及互作,最终诱导各种抗病防卫基因的表达和代谢的变化进而产生抗性。在防卫反应过程中,各类信号分子如激素类(水杨酸、茉莉酸、乙烯、脱落酸),第二信使类(钙离子、活性氧、一氧化氮),低分子肽类(谷胱甘肽),脂类以及糖类发挥着重要作用。最近几年,这些信号分子介导植物抗病反应研究取得重要进展,就此进行了综述,并对今后的研究作出展望。The plants can trigger a series of defensive response against the attack from various pathogens, which includes a variety of signal reactions, such as the generation, transduction and interaction of signals, and then a series of defensive gene expression and metabolic changes, and finally the plants acquire resistance. During the process of defensive reactions, signaling molecules play important roles, such as plant hormones （salicylic acid, jasmonie acid, ethylene and abscisic acid） , the second messengers （Ca2~, ROS and NO） , low molecular peptide （glutathione） , lipids and sugars. Significant progresses have been made in disease resistance response mediated by these signaling molecules in recent years. This paper reviewed the research progress and prospected the future research works.
