摘要:
土传病害是引发连作障碍的关键因素,严重制约着我国集约化农业(特别是种植业)的可持续发展。丛枝菌根(arbuscular mycorrhizal,AM)真菌能够提高宿主抗病性、抑制病原物生长及侵染发病,是农业生产上防控土传病害的重要有益资源,探索其抑病机制和应用技术是近年来的研究热点,但一直缺乏比较系统的理论认识。本文通过梳理相关研究进展发现,AM真菌主要在宿主根系、根际与植株等三个层面发挥抑病作用,其中根系防御主要包括AM真菌与病原物竞争生态位和构建机械防御屏障,根际防御主要包括调节根系分泌物与次生代谢产物及与拮抗菌协同抗病,而植株防御主要包括促进宿主对养分与水分的吸收和诱导宿主产生系统防御体系,因而提出了AM真菌的“根系-根际-植株三级防御”理论。在应用技术方面,我们着重分析了通过接种AM真菌或调动土著AM真菌来防控土传病害的技术研究现状,并对应用中存在的问题及其发展前景进行了展望:一方面可通过建立AM真菌种质资源库或构建转基因工程菌来解决接种有效期及效果稳定性等问题,另一方面可通过改变施肥模式和调整耕作制度来高效调动土著AM真菌的抑病活性,旨在为利用AM真菌防控土传病害、促进集约化种植业可持续发展提供理论依据。(图1 参157)
Abstract:
Soil-borne pathogen, one of the key factors causing continuous cropping obstacle, severely restricts the sustainable development of intensive agriculture (notably plant industry) in China. Arbuscular mycorrhizal (AM) fungi, which can improve the disease resistance of host and inhibit the growth and infection of pathogens, are important beneficial resources to prevent and/or control soil-borne diseases. Although explorating the disease-suppression mechanism and application technology of AM fungi is a hot topic in recent years, there is a lack of relatively systematic theoretical understanding. Based on the collection and reorganization of relevant literature, it is found that AM fungi play the disease suppression role mainly at three aspects, including the root, the rhizosphere, and the plant. The root defense pathway of AM fungi includes the niche competition and the construction of physical defense barrier, the rhizosphere one includes the regulation of root exudates and secondary metabolites and the cooperation with antagonists, while the plant one includes the improvement of nutrients/water uptake and the inducement of system defenses of host, Therefore, a "Three-level defense" theory of AM fungi is proposed, i.e., the root-rhizosphere-plant defense system. Based on the current researches on soil-borne disease suppression via inoculating AM fungi or stimulating indigenous AM fungi, the existing problems and the development prospects of AM fungal application are also proposed. On one hand, it is suggested to establish the germplasm bank of AM fungi or construct transgenic fungi to solve the application problems, such as the term of validity and the stability of effects. On the other hand, is is suggested to stimulate the disease suppression activity of indigenous AM fungi by changing the fertilization patterns and/or the farming systems. It aims to provide theory bases of exploiting AM fungi for the prevention and control of soil-borne disease, and the acceleration of sustainable development of intensive plant industry.
