Advances in the Study of Plant Endophytic Bacteria and Their Effects on Biological Control of Plant Diseases

综述了植物内生细菌及其生物防治植物病害的研究进展。植物内生细菌分布广,种类多,存在于大多数高等植物中,已在生物防治细菌性病害、真菌性病害和线虫病害方面发挥了巨大的作用。植物内生细菌的防病机理主要通过与病原菌竞争生态位和营养物质、产生抗菌活性物质以及诱导植物产生系统抗性等多种作用方式。同时,对植物内生细菌防治植物病害存在的问题及未来发展前景进行了讨论。

Recent advances in the study of endophytic bacteria in plants and their effects on biological control of plant diseases were reviewed. Endophytic bacteria including a wide variety of species and genera are widely distributed and exist in most higher plants. Plant endophytic bacteria have played tremendous roles on biological control of bacterial diseases, fungal diseases and nematode diseases in plants. The mechanism of biological control is by many effect manners such as competing with pathogen for ecological niche and nutrition, producing antibiotic active substances and inducing systemic resistance and so on. In addition,the problems and prospects about endophytic bacteria on biological control of plant diseases were discussed.
