摘要
植物在长期的进化过程中，需要不断地抵抗病原微生物的侵害。在这种长期相互影响的共进化过程中，植物逐渐形成一系列复杂而行之有效的保护机制来抵御病原微生物的侵染。在植物抵御病原微生物侵染的过程中，宿主植物的抗病基因（R）产物与病原微生物无毒基因（Avr）产物的...
In recent years there has been a large they of evidence to suggest that plants have a variety of active mechanisms for defending themselves against microhial pathogenic infeCtions. T'he development of systemicacquired resistance (SAR) and its signal transduction pathway are associated with increased expression of a large number of defense or defense-related genes. Salicylic aeid (SA) is an important signaling molecule in theinduction of disease resistance and the establishment of SAR in plants. There have been two kinds of possiblemechanisms in the establishment of SAR and its signal transduetion pathway among plants.
