“…Stomatal conductance and transpiration rate reflect the water-use efficiency of the vegetation, the photosynthetic efficiency, and the uptake and utilisation of carbon dioxide ( Wang et al, 2021 ). Microorganisms can regulate the expression of plant functional genes through a variety of pathways, thereby increasing the chlorophyll content of leaf cells, improving PS II activity, and promoting photosynthesis ( Tanwar et al, 2022 ; Muhammad et al, 2021 ). In this study, there were significant differences between the photosynthetic parameters of the plants with microbial agent treatments and those in the control group, indicating that the application of microbial agents is conducive to the enhancement of the photosynthetic characteristics of aubergine leaves.…”

Background This study examined the effects of microbial agents on the enzyme activity, microbial community construction and potential functions of inter-root soil of aubergine (Fragaria × ananassa Duch.). This study also sought to clarify the adaptability of inter-root microorganisms to environmental factors to provide a theoretical basis for the stability of the microbiology of inter-root soil of aubergine and for the ecological preservation of farmland soil. Methods Eggplant inter-root soils treated with Bacillus subtilis (QZ_T1), Bacillus subtilis (QZ_T2), Bacillus amyloliquefaciens (QZ_T3), Verticillium thuringiensis (QZ_T4) and Verticillium purpureum (QZ_T5) were used to analyse the effects of different microbial agents on the inter-root soils of aubergine compared to the untreated control group (QZ_CK). The effects of different microbial agents on the characteristics and functions of inter-root soil microbial communities were analysed using 16S rRNA and ITS (internal transcribed spacer region) high-throughput sequencing techniques. Results The bacterial diversity index and fungal diversity index of the aubergine inter-root soil increased significantly with the application of microbial fungicides; gas exchange parameters and soil enzyme activities also increased. The structural and functional composition of the bacterial and fungal communities in the aubergine inter-root soil changed after fungicide treatment compared to the control, with a decrease in the abundance of phytopathogenic fungi and an increase in the abundance of beneficial fungi in the soil. Enhancement of key community functions, reduction of pathogenic fungi, modulation of environmental factors and improved functional stability of microbial communities were important factors contributing to the microbial stability of fungicide-treated aubergine inter-root soils.
