摘要

人参根际微生物群在促进植物生长、增强抗逆性和促进药理意义的人参皂苷的生物合成等方面发挥着重要作用。然而,连续的单作破坏了微生物群落的平衡,导致土壤退化、土传病原体的增殖和作物生产力的下降。先进的多组学技术,如宏基因组学和代谢组学,为人参根际微生物群的结构和功能提供了有价值的见解。这些研究强调了其在营养动员、疾病抑制和应激缓解方面的潜力。根渗出物,包括酚酸和人参皂苷,影响微生物组成;然而,它们也可能通过促进致病真菌而加剧土壤失衡。相反,有益微生物,如磷酸盐增溶菌和产铁载体菌株,可以提高养分利用率,减轻重金属毒性,并通过生物活性代谢物抑制病原体。这篇综述强调了人参根际微生物组的功能作用,并强调了利用微生物相互作用进行可持续栽培的知识空白。更全面地了解植物与微生物的相互作用,再加上微生物组驱动策略的整合,可以提高人参的生产力,提高生物活性化合物的产量,并支持环境可持续的农业实践。这些发现为推进微生物组研究和解决人参栽培中的挑战提供了基础。

Composition, Diversity, and Functional Roles of the Rhizosphere Microbiome in Panax ginseng.

The rhizosphere microbiome of Panax ginseng plays a crucial role in promoting plant growth, enhancing stress resilience, and facilitating the biosynthesis of pharmacologically significant ginsenosides. However, continuous monocropping disrupts the microbial community balance, leading to soil degradation, the proliferation of soilborne pathogens, and decreased crop productivity. Advanced multi-omics technologies, such as metagenomics and metabolomics, have provided valuable insights into the structure and function of the ginseng rhizosphere microbiome. These studies highlight its potential for nutrient mobilization, disease suppression, and stress mitigation. Root exudates, including phenolic acids and ginsenosides, influence microbial composition; however, they may also exacerbate soil imbalances by promoting pathogenic fungi. Conversely, beneficial microbes, such as phosphate-solubilizing bacteria and siderophore-producing strains, enhance nutrient availability, mitigate heavy metal toxicity, and suppress pathogens through bioactive metabolites. This review emphasizes the functional roles of the ginseng rhizosphere microbiome and highlights knowledge gaps in leveraging microbial interactions for sustainable cultivation. A more comprehensive understanding of plant-microbe interactions, coupled with the integration of microbiome-driven strategies, can enhance ginseng productivity, boost bioactive compound yields, and support environmentally sustainable agricultural practices. These findings provide a foundation for advancing microbiome research and addressing challenges in ginseng cultivation.
