摘要
植物对病原物的抗性是一个很复杂的生命现象。目前人们认识到植物的抗病过程有很多基因和一些相互关联的信号传导途径参与。人们对植物抗病的分子机制的了解,很多是来自以拟南芥作为材料所进行的大量研究。对植物抗病性的了解是一步步深入的,其进展与研究方法和技术的不断改革密不可分,其中实验材料的模式化使得研究更加集中、更具有通用性,所使用的资源更丰富,强有力地推进了研究的深入进行。在此,对拟南芥这个模式植物在植物抗病性的遗传和分子机制研究中的作用做了阐述。
Plant resistance to pathogens is a very complicated bio-phenomenon, loaay, people realize that both signal transduction pathways and many genes are involved in the resistant processes of plants. The understanding of resistant molecular mechanism is based mostly on the large number of experimental re- sults using Arabidopsis as research material. These developments occurred as a result of improvements in research methods and techniques. Research using Arabidopsis thaliana as a model plant has enhanced our understanding of the molecular mechanism of plant resistance to pathogens. The use of Arabidopsis as a model plant has become ubiquitous, allowing efficient and readily-reproducible experimental results. In this paper we review the discovery and cloning process of resistant genes, the research of resistant signal transduction and the recent transcription regulation study in resistant genes. The role of Arabidopsis as a research model plant in the study of genetic and molecular mechanisms of plant resistance to pathogens are discussed.
