“…Specifically, Fusarium , known for causing chrysanthemum wilting, demonstrated an increased relative abundance in the rhizosphere of chrysanthemums. This observation concurs with the findings presented by Zeng et al, who concluded that Fusarium plays a significant role in the pathogenesis of chrysanthemum wilting, and its elevated presence in the rhizosphere is indicative of a potential disease outbreak [ 26 ]. The RDA analysis results of this study indicated that soil nutrient factors exert a substantial impact on microbial composition, with pathogenic bacteria being the main influencing factor in the composition of rhizosphere bacterial community.…”

Chrysanthemum wilt is a plant disease that exerts a substantial influence on the cultivation of Chrysanthemum zawadskii (Herb.) for tea and beverage production. The rhizosphere microbial population exhibits a direct correlation with the overall health of plants. Therefore, studying the rhizosphere microbial community of Chrysanthemum zawadskii (Herb.) Tzvel. is of great significance for finding methods to control this disease. This study obtained rhizosphere soil samples from both diseased and healthy plant individuals and utilized high-throughput sequencing technology to analyze their microbial composition. The results showed that the rhizosphere microbial diversity decreased significantly, and the microbial community structure changed significantly. In the affected soil, the relative abundance of pathogenic microorganisms such as rhizospora and Phytophthora was greatly increased, while the relative abundance of beneficial microorganisms such as antagonistic fungi and actinomyces was greatly decreased. In addition, this study also found that soil environmental variables have an important impact on plant resistance; the environmental factors mainly include soil properties, content of major microorganisms, and resistance characteristics of samples. Redundancy analysis showed that the drug-resistant population had a greater impact on the 10 species with the highest abundance, and the environmental factors were more closely related to the sensitive population. In the fungal community, the resistant sample group was more sensitive to the influence of environmental factors and high-abundance fungi. These findings provide a theoretical basis for improving microbial community structure by optimizing fertilization structure, thus affecting the distribution of bacteria and fungi, and thus improving the disease resistance of chrysanthemum. In addition, by regulating and optimizing microbial community structure, new ideas and methods can be provided for the prevention and control of chrysanthemum wilt disease.

Chrysanthemum wilt is a plant disease that exerts a substantial influence on the cultivation of Chrysanthemum zawadskii (Herb.) for tea and beverage production. The rhizobial microbial population exhibits a direct correlation with the overall health of the plants. Therefore, studying the rhizosphere of CZHZ microbial communities would be of great significance for finding methods to control this disease. This study collected rhizosphere soil samples from diseased and healthy strains and analysed their microbial composition using high-throughput sequencing technology. The results showed that the diversity of rhizosphere microorganisms in the diseased strains was considerably reduced, and the microbial community structure of the diseased strains underwent significant changes compared to the healthy strains. In addition, the relative abundance of pathogenic microorganisms, such as root rot fungi and phytophthora, significantly increased, while the beneficial micro-organisms (e.g. antagonistic bacteria and Actinomyces) decreased significantly in the rhizosphere soil of the diseased strains. The positive correlation between bacteria and environmental factors indicates that environmental factors may have a substantial impact on the abundance and species of fungi in soil. Our results show that we can prevent the occurrence of wilt disease by adjusting the physiochemical properties of the rhizosphere soil and by changing the microbial communities. However, by regulating and optimising the microbial community structure, new ideas and methods can be provided for the prevention and control of chrysanthemum wilt disease.

Plant diseases are a major threat affecting the sustainability of global agriculture. Although the breeding of new resistant cultivars is considered to be the primary approach to prevent and control plant diseases, it is dependent on an in‐depth understanding of plant–pathogen interactions. At present, we have an in‐depth understanding of the interactions between model plants and pathogens, such as Arabidopsis thaliana and rice, but we are still in the beginning stage for more non‐model plants (e.g., medicinal plants). Panax notoginseng is the primary source of the high‐value active ingredient triterpenoid saponins. Root rot disease in P. notoginseng has attracted research attention because of its high destructiveness. Understanding the infection stages and strategies of pathogens, plant resistance mechanisms and induced plant defence against pathogens is essential to support agricultural sustainable development of P. notoginseng. Here, we review and summarize, with root rot of P. notoginseng as a model, the current knowledge of plant–pathogen interaction, and feasability of use of microorganisms and secondary metabolites as sources of biological control agents at a low cost. Finally, we also discuss the importance of plant–pathogen interactions in resistance breeding, thereby providing a new strategy to develop green agriculture for non‐model plants.
