“…However, increasing attention has been given to enhancing root-soil-microbial interactions by selecting crop varieties/genotypes, optimizing crop spatiotemporal combinations, improving nutrient inputs, developing smart fertilizers, and applying soil or microbiome inoculations. Enhancing root-soil-microbial interactions can increase yields and reduce pest and disease stress in farming systems, and it can also reduce greenhouse gas emissions and enhance soil carbon sequestration [72]. Biodiversity can enhance ecosystem services.…”

Intercropping systems can flexibly use resources such as sunlight, heat, water, and nutrients in time and space, improve crop yield and land utilization rates, effectively reduce continuous cropping obstacles and the occurrence of diseases and insect pests, and control the growth of weeds. Thus, intercropping is a safe and efficient ecological planting mode. The legume–cereal intercropping system is the most common planting combination. Legume crops fix nitrogen from the atmosphere through their symbiotic nitrogen fixation abilities, and the fixed nitrogen can be transferred to and utilized by cereal crops in various ways. The symbiotic nitrogen fixation efficiency of legume crops was improved by reducing the inhibition of soil nitrogen on nitrogenase activity through competitive absorption of soil nitrogen. However, the effects of nitrogen transformation and distribution in intercropping systems, and microbial community structure characteristics on nitrogen transfer need to be further explored. In this review, ⅰ) we present the transformation and distribution of nitrogen in the legume–cereal intercropping system; ⅱ) we describe the soil microbial community characteristics in intercropping systems; and ⅲ) we discuss the advantages of using modern biological molecular techniques to study soil microorganisms. We conclude that intercropping can increase the diversity of soil microorganisms, and the interaction between different plants has an important impact on the diversity and composition of the bacterial and fungal communities. The extensive application of modern biological molecular techniques in soil microbial research and the great contribution of intercropping systems to sustainable agriculture are particularly emphasized in this review.

Editorial on the Research Topic Plant microbiome: Diversity, functions, and applications Considerable attention on plant microbiomes has been growing over the past decade featuring model plants, natural, and agricultural crop systems (Berg et al., 2020;Chialva et al., 2022). Studies are being carried out to understand microbial community composition, assembly process and underlying factors, evolution and ecology, and functional roles (Compant et al., 2019;Dastogeer et al., 2020; Xu et al., 2021;Trivedi et al., 2022). The power of advanced omics and multi-omics techniques, computational power, biostatistics, and remodeling of biological and evolutionary theories allows for a deeper understanding of plant--microbiome interactions (Subramanian et al., 2020; Xu et al., 2021). The study of how the microbiome interacts with other elements of the environment is gaining momentum, and efforts are being made to understand the functional roles of the microbiome in translating microbiome potentials into sustainable plant production and protection. Currently, the engineering of microbial flora and the development and application of the synthetic community (SynComs) approach have revealed an essential role of microorganisms in plant adaptability and productivity (Liu et al., 2019;Nerva et al., 2022).This Research Topic hosts eleven original research articles and a review article. The original research articles span experimental findings of various plants with their associated microbes, such as apple, aspen, avocado, chrysanthemum, eucalyptus, licorice, morning glories, tea, tobacco, and yellow witchweed.

“…Additionally, many soil microorganisms can promote plant growth by secreting plant growth hormones, solubilizing phosphate, or fixing nitrogen [ 4 ]. However, intensified management practices of farming, high agrochemical inputs and simplified cropping systems, can result in legacy effects on the soil microbiome [ 5 – 8 ] that may indicate changes to soil function [ 9 – 11 ]. In order to enhance plant fitness and productivity, it is necessary to understand how these varied and repeated crop management activities can be used to optimize soil and plant microbiome.…”

Background Soil microorganisms are integral to maintaining soil health and crop productivity, but fumigation used to suppress soilborne diseases may affect soil microbiota. Currently, little is known about the legacy effects of soil fumigation on soil microbial communities and their response to fumigation at the production scale. Here, 16S rRNA gene and internal transcribed spacer amplicon sequencing was used to characterize the bacterial and fungal communities in soils from intensively managed crop fields with and without previous exposure to metam sodium (MS) fumigation. The effect of fumigation history, soil series, and rotation crop diversity on microbial community variation was estimated and the response of the soil microbiome to MS application in an open microcosm system was documented. Results We found that previous MS fumigation reduced soil bacterial diversity but did not affect microbial richness and fungal diversity. Fumigation history, soil series, and rotation crop diversity were the main contributors to the variation in microbial β-diversity. Between fumigated and non-fumigated soils, predominant bacterial and fungal taxa were similar; however, their relative abundance varied with fumigation history. In particular, the abundance of Basidiomycete yeasts was decreased in fumigated soils. MS fumigation also altered soil bacterial and fungal co-occurrence network structure and associations. In microcosms, application of MS reduced soil microbial richness and bacterial diversity. Soil microbial β-diversity was also affected but microbial communities of the microcosm soils were always similar to that of the field soils used to establish the microcosms. MS application also induced changes in relative abundance of several predominant bacterial and fungal genera based on a soil’s previous fumigation exposure. Conclusions The legacy effects of MS fumigation are more pronounced on soil bacterial diversity, β-diversity and networks. Repeated fumigant applications shift soil microbial compositions and may contribute to differential MS sensitivity among soil microorganisms. Following MS application, microbial richness and bacterial diversity decreases, but microbial β-diversity was similar to that of the field soils used to establish the microcosms in the short-term (< 6 weeks). The responses of soil microbiome to MS fumigation are context dependent and rely on abiotic, biotic, and agricultural management practices.
