Abstract

Dendrobium officinale Kimura et Migo has long been utilized in traditional Chinese medicine and other Asian cultures for its medicinal properties. One of the key bioactive compounds found in D. officinale is D. officinale polysaccharides (DOPs). Recent studies have indicated that the rhizosphere microbiome can influence the accumulation of bioactive compounds in medicinal plants. Our findings revealed that the bacterial phylum Bacteroidetes played a significant role in shaping the ecological stability of the rhizosphere bacteria associated with D. officinale. Additionally, Pandoraea may have the potential to enhance the production of polysaccharides in D. officinale. Overall, this research contributes to our understanding of the intricate relationship between the rhizosphere microbiome and the accumulation of bioactive compounds in D. officinale. It highlights the potential of specific bacterial taxa, such as Pandoraea, in promoting the production of polysaccharides, thus further establishing the medicinal value of this plant. Our results provide insights for further development of specific fertilizers for medicinal plants.

铁皮石斛多糖的积累与根瘤菌密切相关。

木村和三乡（Kimura et Migo）的铁皮石斛因其药用特性长期以来一直被中国传统医学和其他亚洲文化所利用。欧石斛中发现的主要生物活性化合物之一是欧石斛多糖（DOPs）。最近的研究表明，根圈微生物群可影响药用植物中生物活性化合物的积累。我们的研究结果表明，细菌门类杆菌在影响与 D. officinale 相关的根瘤菌生态稳定性方面发挥了重要作用。此外，Pandoraea 可能具有提高 D. officinale 多糖产量的潜力。总之，这项研究有助于我们了解根瘤微生物群与 D. officinale 中生物活性化合物积累之间的复杂关系。它强调了特定细菌类群（如 Pandoraea）在促进多糖生产方面的潜力，从而进一步确定了这种植物的药用价值。我们的研究结果为进一步开发药用植物专用肥料提供了启示。
