摘要
草类植物病害是限制草牧业生产和发展的主要因素之一。目前抗病品种的开发利用是目前防治病害最经济有效的方法,植物抗病机制的研究对开发抗病品种和构建生态环境友好型病害防治至关重要。植物受病原菌侵染时形成多种复杂的防御机制,本研究主要从植物组织结构抗性、生理生化抗性、抗性基因和抗性数量性状位点(QTLs)定位等分子机制方面综述草类植物抗病机制研究进展,并提出我国草类植物抗病机制研究中面临的主要问题与解决办法,以期为草类植物抗病育种提供理论依据。
Grass disease is one of the major limiting factors for the development of forage industries. At present,the development and utilization of resistant cultivar is the most economical and effective disease management strategies.Research on plant disease resistance mechanisms is essential for the development of resistant cultivar and the construction of eco-environmental friendly disease prevention and control measures. Plants form a variety of defense mechanisms when they are infected by pathogens. This study summarized the research advances relating to disease resistance mechanism, including tissue resistance, physiological and biochemical resistance, and molecular mechanism involving resistance genes and quantitative trait loci(QTLs) related to disease resistance traits. The major problems and opportunities for solutions in the research into resistance mechanisms of herbaceous plants are identified,which provides a theoretical basis for breeding of grass disease resistance.
