%X 由青枯雷尔氏菌引起的青枯病是影响农作物产量的主要病害之一，而我国对青枯病的防治目前尚未发现十分行之有效的措施。因此，了解青枯菌与植物的互作模式，对开辟防治青枯病的新思路具有重要意义。笔者在国内外学者研究文献的基础上，简单归纳了植物青枯菌的分类系统及发病特征，从分子水平上阐述了青枯菌在寄主植物根细胞间隙定植的侵染过程以及致病机理，从形态学、生理生化和基因表达调控三个方面分析了植物对青枯菌的抗性机制，指出了农业防治、药剂防治、生物防治等防治青枯病措施的局限性，并简要介绍了抗青枯病分子育种的研究进展。认为种植抗青枯病的多系品种和混合品种是控制青枯病危害的有效途径，据此提出挖掘多抗原抗性基因，进而培育抗青枯病新品种是防治青枯病的重要发展方向。<br />
Bacterial wilt caused by Ralstonia solanacearum is one of the main diseases which affect crop yield. However, no effective measures have been found to control bacterial wilt in China. Therefore, understanding the interaction mode between Ralstonia solanacearum and plants is of great significance to develop new ideas for the control of bacterial wilt. On the basis of the literature of domestic and foreign scholars, the classification system and pathogenic characteristics of Ralstonia solanacearum were summarized, the infection process and pathogenic mechanism of Ralstonia solanacearum colonization in the root intercellular space of host plants were elaborated from the molecular level, and the resistant mechanism of the plant to Ralstonia solanacearum was analyzed from the aspects of morphology, physiology, biochemistry and regulation of gene expression. In addition, the limitation of agricultural control, chemical control and biological control of bacterial wilt was pointed out, and the research progress of molecular breeding for bacterial wilt resistance was briefly introduced. It is considered that planting multi-line varieties and mixed varieties with resistance to bacterial wilt is an effective way to control the damage of bacterial wilt. Accordingly, it is suggested that mining multi-antigen resistance genes and breeding new varieties resistant to bacterial wilt is an important development direction for the control of bacterial wilt.
