Summary: This study analysed the diversity and abundance of endophytic microbes in different organs of Panax ginseng using high-throughput sequencing. The results showed that the composition of endophytic microbes varied among the roots, stems, and leaves, with different dominant bacterial and fungal genera. The roots had the highest diversity of endophytic bacteria, while the stems had a higher abundance of Ochrobactrum bacteria and Coniothyrium and Cladosporium fungi. The study provides important insights into the endophytic microorganisms in ginseng.

Summary: The rhizosphere of ginseng contains a wide range of microorganisms that can have beneficial or harmful effects on the plant. Cultivation practices that mimic natural conditions of ginseng may disrupt soil microbiome, leading to negative changes in soil physiochemistry and promotion of plant diseases. However, beneficial microbes isolated from the ginseng rhizosphere show potential to improve ginseng production. High-throughput sequencing has greatly expanded our knowledge of the diversity and abundance of rhizosphere organisms and their impacts on cultivation.

Summary: Ginsenosides have been widely studied for their medicinal benefits and their role in ginseng plant biology. They play a crucial role in ginseng's defense against biotic stresses, providing antimicrobial, antifeedant, and allelopathic activities. Ginsenosides also have roles in ginseng development and abiotic stress tolerance.

Summary: Chromium contamination has significant effects on the microbial communities in ginseng-growing soil. Specific microbial groups are positively correlated with the levels of potassium, phosphorus, and nitrogen, while negatively correlated with the levels of total chromium and available chromium. These findings provide important insights into the impacts of chromium contamination on ginseng growth.

Summary: This study analyzed the microbial communities in the rhizosphere soils of three types of ginseng using high-throughput sequencing. The results showed that bacterial diversity was higher and fungal diversity was lower in the rhizosphere soils of wild ginseng compared to farmland cultivated ginseng. The study also found that fungal communities were more affected than bacterial communities in all three types of ginseng. Furthermore, the relative abundance of Chloroflexi, Fusarium, and Alternaria was higher in farmland cultivated ginseng compared to wild ginseng and understory wild ginseng.

Summary: Replant disease caused by continuous cropping commonly occurs in yam with consecutive monoculture. However, little is known about how the continuous cropping of yam affects the rhizospheric soil bacterial community structure. In this study, the effects of continuous cropping on rhizospheric soil characteristics, bacterial diversity, and community structure were investigated in the Yongfeng yam fields under monoculture for 1, 5, 10, 15, and 20 years. Long-term monoculture caused soil acidification and increased the concentration of available potassium (AK) and available phosphorus (AP), and soil bacterial richness, but decreased the soil bacterial diversity. An exception was for the field under monoculture for 20 years as it showed the highest bacterial diversity. The relative abundance of beneficial bacteria, such as Proteobacteria, Actinobacteria, and Chloroflexi decreased while the relative abundance of harmful bacteria, including Gemmatimonadetes and Acidobacteria, increased with an extended continuous cultivation time. The networks varied among yams with different cultivation years and became complex with the increase in cultivation years. However, after time in monoculture, the bacterial network decreased gradually and existed stably. These changes in bacterial community composition and co-occurrence of networks may increase the potential risk of soil-borne disease and reduce the yield and quality of Yongfeng yam.
