类芽胞杆菌(Paenibacillus)对植物促生御病机理研究进展

Advances in Mechanisms of Paenibacillus to PromoteGrowth&Diseases-Defending in Plant

类芽胞杆菌(Paenibacillus)是植物根际促生菌的重要来源,可通过固氮、产生激素、分泌铁载体、活化矿物营养元素等机制直接促进植物生长;也可通过诱导植物抗病性、产生各类抗菌活性物质等机制抵御植物病害。因其特性符合植物促生和病害生物防治的需要,在可持续农业中发挥越来越重要的作用。从自身代谢角度综述类芽胞杆菌对植物促生御病机制的研究进展,梳理了组学技术在相关研究中应用所取得的成果,展望了未来研究的发展趋势,并对今后的研究提出了三点建议。

Paenibacillus is important resources of plant growth-promoting rhizobacteria,which can promote plant growth by fixing nitrogen,producing hormones,excreting siderophores,and activating mineral nutritive elements and other mechanism that directly promote the plant growth.It also can help plants defend against diseases by inducing plant disease resistance and producing kinds of antibacterial substances and other mechanisms.Because its characteristics accord with the needs of plant growth promotion and disease biological control,Paenibacillus will play an increasingly important role in sustainable agriculture.In this paper,advances in the mechanism of Paenibacillus promoting growth and defending diseases in plant were reviewed from the perspective of autologous metabolism,the achievements of correlational researches were combed,on which omics technologies were applied,the trends of future researches were look forward,and then three suggestions for future researches were put forward.
