This research topic focuses on advancing understanding of recent studies on interactions between economic crops and microbiomes. A total of 15 manuscripts were submitted, of which 9 articles were published, including 8 original research articles and 1 mini-review. These studies involve 7 crops-rice, Rheum officinale, citrus, maize, pepper, mango, and Aloe vera-and specifically describe the roles of Botryosphaeria dothidea, Aureobasidium pullulans, and Burkholderia gladioli in economic crops. The articles cover various biological and abiotic stress-related topics, such as plant nitrogen use efficiency, phosphorus solubilization and growth promotion, crop quality improvement, aphid infestation, and pathogen pathogenicity.Bziuk et al. systematically explored the global distribution, ecological functions, and application potential of Aureobasidium pullulans within the frameworks of sustainable agriculture and the "One Health" concept, adopting a fungus with significant application value, from a novel microbiome-based perspective. Using the publicly available GlobalFungi database, the authors generated a macroscale global distribution map of A. pullulans. The analysis revealed a truly global distribution, with significantly higher detection rates in environments closely associated with human activities compared to natural ecosystems, highlighting a strong link to anthropogenic influence.These findings not only confirm the established value of A. pullulans as an effective biocontrol agent but also identity it as a natural core member of the plant microbiome.The results indicate that A. pullulans is not a transient colonizer but a resident symbiotic fungus with significant ecological influence. As a common component of the edible microbiome, A. pullulans may enter the human body through the food chain. Its potentially effects on the gut microbiome and human health was preliminarily explored, elevating its ecological significance to a "One Health" level that integrates plant, environmental, and human health. These findings provide a theoretical foundation for future in-depth development and application of A. pullulans in sustainable agriculture and health-related fields.To explore how soybean green manure with different intercropping durations affects citrus fruit quality by altering soil physicochemical properties and microbial communities in acidified citrus orchards, Deng et al. established field experimental groups with varying intercropping durations. They systematically measured citrus fruit quality indicators and soil physicochemical properties and analyzed the community structures of soil bacteria and fungi using high-throughput sequencing. Through correlation network analysis, they revealed complex associations among intercropping duration, soil parameters, key microbial groups, and fruit quality. Soybean green manure significantly enhanced fruit quality, improved the soil environment, and reshaped the soil microbial community. Intercropping soybean green manure in citrus orchards is an effective ecological agricultural practice. Its core mechanism is the synergistic improvement of fruit quality through dual pathways: enhancement of soil physicochemical properties and regulation of soil microbial communities. This study provides a solid theoretical and practical basis for applying green manure intercropping in acidified orchard soils to support sustainable ecological restoration and improve agricultural production efficiency. and their structure varies significantly among varieties. Rare taxa are the main drivers of community diversity and differentiation, while core taxa are highly conserved across varieties, primarily composed of high-abundance taxa, and occupy central positions in the co-occurrence network, thereby maintaining community stability. Five representative bacterial strains successfully isolated from seeds exhibited various plant growth-promoting characteristics in vitro, including siderophore production, phosphate solubilization, and indole-3-acetic acid synthesis. All strains promoted rice growth, increased nitrogen accumulation, and enhanced NUE. However, their growthpromoting effects were co-regulated by strain identity and nitrogen supply levels.Under low nitrogen conditions, the growth-promoting effects of the strains were pronounced, highlighting their potential for application in nutrient-stressed environments. The endophytic bacterial community within rice seeds co-evolve with the host through strategies of innovation and adaptation driven by rare taxa, and stability and inheritance maintained by core taxa. These natural symbiotic bacterial communities, as microbial allies of the host, enhance host adaptability in low-nitrogen soils through synergistic mechanisms such as nitrogen fixation, regulation of nitrogen metabolism, and production of plant hormones. Future research will focus on multi-dimensional analyses of plant-microbiome interaction networks. Synthetic biology and genome-editing technologies will facilitate the design of customized microbial communities, such as constructing SynComs with nitrogen fixation, phosphorus solubilization, and disease-resistance functions, enabling precise regulation of multiple effects from a single microbial inoculum. Simultaneously, strategies to enhance environmental adaptability are crucial. By utilizing directed evolution and metabolic engineering to modify microbial metabolic pathways, colonization stability under adverse conditions such as salinity, alkalinity, and drought can be improved. Furthermore, interdisciplinary collaboration will accelerate the exploration and industrialization of microbial resources, developing innovative solutions for agricultural carbon neutrality and food security, including living biopesticides based on endophytes and the construction of rhizosphere microbial seed banks.
