“…The powdery mildew family is the Ascomycetes family. Its species is a parasitic fungus in the aerial parts of higher plants, which contains many plant pathogens and is the main source of toxins that cause plant diseases [ 24 ]. The RDA analysis revealed that soil nutrient factors had a more significant effect on microbial composition and that pathogenic bacteria were the main influencing factor in the assembly of the inter-rooted 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.

The Erysiphaceae family is a diverse group of fungi with complex evolutionary relationships. All previous data for powdery mildew fungi in Ile-Alatau are outdated and needed to be revised due to changes in the Erysiphaceae taxonomy. The purpose of our research was to revise all data and to compile an actual checklist of Erysiphaceae in the Ile-Alatau based on revisions of the available fungal samples of the Herbarium Fund of the Institute of Botany and Phytointroduction of the Republic of Kazakhstan, the authors' own collections and a critical revision of the genera. Mycological survey of the territory of the Ile-Alatau was done by the route method during 2013-2020. An actual checklist of powdery mildews in the Ile-Alatau Mountains was compiled. The powdery mildews are represented by 91 species of 8 genera. The largest genus is Erysiphe containg 30 species and forms recorded on 99 angiosperm host plant species. The genera Podosphaera and Golovinomyces have 20 and 17 species, respectively. Totally, 40 species were recorded as host plants for the first time, including 24 of them due to taxonomic revisions. The greatest number of species and forms of powdery mildews is noted at altitudes of 1200-2000 m above sea, in the forest belt of Ile-Alatau Mountains. Three most numerous genera-Erysiphe, Golovinomyces, Podosphaera-prevail in all gorges and habitats. Five species were found on plants listed in the Red Book of Kazakhstan. The coefficient of similarity of the species composition of powdery mildew fungi on the territory of the Ketmen and Ile-Alatau ridges is 60%, while on the territory of the Terskey and Ile-Alatau ridges 70%. The value of the study and practical significance lies in obtaining data on the diversity of powdery mildew fungi in the Ile-Alatau Mountains, their location, distribution and association with the host.
