| 中文摘要: |
| 植物促生菌(plant growth-promoting bacteria，PGPB)因其在促进植物生长、增强植物抗病性与抗逆性、提高作物产量和质量中的重要作用受到广泛关注。相较于传统植物施肥促生方式，PGPB具有广谱性、长效性、生态环境安全性等优点，在化学肥料广泛施用破坏生态环境的背景下具有良好的应用前景。PGPB对宿主植物的有效定殖是保证其促生效果稳定的关键。因此，如何使PGPB成功定殖于宿主植物并提高其定殖效率、充分发挥其功能，成为研究的重点。本文通过阐述PGPB的主要功能、定殖(途径与检测方法)及影响因素(PGPB自身特性、植物根系分泌物、微生物之间的相互作用、非生物环境影响等)，重点探讨了提高PGPB定殖效率的方法，如基因工程改造菌株、外源添加植物根系分泌物、载体固定及合成菌群等。本文为理解PGPB的定殖及影响因素，进而提高PGPB定殖效率提供理论依据和技术参考，对保障农业可持续发展具有积极意义。 |
| 英文摘要: |
| Plant growth-promoting bacteria (PGPB) have received intensive interests due to its important roles in improving plant growth, disease resistance and stress tolerance, crop yield and quality. The distinct benefits of PGPB-based technologies include diverse spectrum of action, future effectiveness, and environmental safety, which are compared to traditional fertilization because in most cases chemical fertilizers cause extensive environmental harm. The colonization of host plants by the PGPB must be effective in order to provide stable growth-promoting effects. Hence, the enhancements in colonization and PGPB functional expression have become a major research topic. In this review, an overview of the principle functions of PGPB, their mode of colonization (pathways and detectability mechanisms), and factors that affect colonization including bacterial characteristics, root exudate composition, microbial interactions, and abiotic environmental factors are discussed. Among the strategies to improve the efficiency of PGPB colonization, this review covers genetic engineering of the bacterial strains, nature exogenous use of plant root exudates, microbial immobilisation methods, and artificial microbial consortia. It creates a theoretical base and work roadmap to comprehend the overall principles of PGPB colonization and maximize their performance and provides real-life resolutions to ensure sustainable agriculture. |
