    Abstract

    The plant-microbe interactions, which is crucial for plant health and productivity, mainly occur in rhizosphere: a narrow zone of soil surrounding roots of living plants. The rhizosphere hosts one of the most intense habitats for microbial prey–predator interactions, especially between predatory protists and bacteria. Here, based on two key facts, microbial predators modulate rhizobacterial community composition, and the rhizobacterial community is the primary source of root microbiome, endophytes; we hypothesized that predation upon rhizobacteria would modulate the community composition of endophytic bacteria. The effects of three taxonomically distinct axenic protist species (Acanthamoeba castellanii, Vermamoeba vermiformis, and Heteromita globosa) were tested in this study. To examine the robustness of the hypotheses, the experiments were conducted in three soil types characterized by distinct bacterial communities and physicochemical properties. The bacterial community compositions were analyzed with high throughput sequencing. Bacterial gene abundances were estimated with a real-time-PCR method. The results showed that protists modulated endophytic communities, which originated in the rhizosphere soil. The modulation of endophytic communities by protists showed chaotic patterns rather than a deterministic effect under different soil types. The observed chaotic dynamics were further confirmed with an additional experiment, in which chaos was triggered by changes in the dilution rates of soil nutrients. Furthermore, the presence of predators enhanced the root colonization of endophytes. Our findings identify a key mechanism for the modulation of root endophytes and enhance understanding of underground plant-microbe interactions, which can lead to open new avenues for modulating the root microbiome to enhance crop production.

  • Biochar–microbe interaction: more protist research is needed Reviewed

    Abstract

    Biochar applications have an enormous impact on the soil microbial community and functionality. However, the majority of the knowledge on biochar–microbe interaction derives almost exclusively from bacterial and fungal studies, while the vast majority of eukaryotic diversity, protists, are mostly neglected. Protists play important roles in the soil ecosystem as microbial predators, decomposers, photoautotrophs, pathogens, and parasites and they are essential for a healthy soil ecosystem. Toward a comprehensive understanding of the effects of biochar application, we need more studies on protists across the full breadth of eukaryotic diversity. The aim of this article is to highlight the research needs and discuss potential research ideas on biochar–protist interaction, which would advance our knowledge of biochar–microbe interaction.

    Highlights

    Biochar–microbe interaction is almost exclusively studied for bacteria and fungi.

    Only a few studies are available on how soil protists react to biochar application.

    More research on biochar–protist is needed for a better understanding of biochar–microbe interaction.

    <p lang="en">To overcome the global problem of food shortage while supporting sustainable life on Earth, we must appreciate the critical importance of soil microorganisms—the key drivers of essential ecosystem services such as nutrient cycling and plant productivity. Protists are one of the major microbial groups in soil ecosystem including primary producers, decomposers, predators, and symbionts. The diverse morphologies and feeding strategies of predatory protists, including amoebae, ciliates, and flagellates, contribute to their versatility in capturing prey. Particularly, trophic interactions between protists and bacteria play a crucial role in regulating bacterial communities in the soil. Protists selectively prey on bacteria, influencing community composition, and enhancing microbial activity. The impact extends to nutrient cycling, secondary metabolite production, and even antibiotic resistance in soil bacterial communities. Despite recent advances, the field of applied protistology remains underexplored, necessitating further research to bridge the gap between theoretical potential and practical application. We call for increased scientific attention, research efforts, and practical implementations to fully harness the benefits of soil protistology for future agricultural practices. In this article, we introduced the frequently overlooked essential roles of predatory protists in soil ecosystem and their potential usage in sustainable agriculture.</p>

  • The Application of Organic Matter Temporarily Shifts Carrot Prokaryotic Communities in the Endosphere but Not in the Rhizosphere

    Endophytic prokaryotes, bacteria, and archaea, are important microorganisms that benefit host plants by promoting plant growth and reducing stress. The objective of this study was to evaluate temporal shifts in the root endophytic prokaryotic communities associated with carrots (Daucus carota subsp. sativus) and the effect of organic matter application on them. Carrots were grown in a planter under five fertilizer treatments (weed compost, bark compost, cattle manure, chemical fertilizer, and no-fertilizer control) and the compositions of rhizosphere and root endosphere prokaryotic communities were determined via amplicon sequencing analysis targeting the 16S rRNA gene at 60 and 108 days after sowing. The results showed that the rhizosphere prokaryotic community compositions were stable despite different sampling times and fertilizer treatments; however, a greater temporal shift and an effect of the type of organic matter applied were observed in the endosphere prokaryotic communities. The differences in treatments resulted in significant differences in the abundance and Faith pyrogenetic diversity of the endosphere prokaryotic community. Genera, such as Burkholderia, Sphingomonas, and Rhodanobacter, that exhibit plant-growth-promoting and biocontrol activities, were detected regardless of the treatments, suggesting that they may play an important ecological role as the core endophytes in carrot roots.

    Rice roots provide a specific habitat for microorganisms in the rhizosphere of a submerged field through supply of oxygen and organic matter. Many studies have focused on the microbial community in the rice rhizosphere, but less is still known about the microeukaryotic community structure of rice rhizosphere. This study explored the microeukaryotic community structure of a rice rhizosphere through denaturing gradient gel electrophoresis (DGGE) targeting 18S rRNA gene. The rice roots and the rhizosphere soil samples, which were collected from a field under rice-wheat rotation system, were separately analyzed. To characterize the rice rhizosphere-specific community, the bulk soil of rice field and the wheat rhizosphere samples were also examined. DGGE fingerprints showed that the microeukaryotic community of rice roots were distinct from the community of the bulk soil and showed a temporal shift with the growth stage. The rhizosphere soil community was distinct from the root and bulk soil communities, but this could be explained by that the root and bulk soil communities were shared in the rhizosphere. The rice rhizosphere community was also distinct from those in the wheat rhizosphere. Microeukaryotes that characterized the rice rhizosphere (roots and the rhizosphere soil) community could be affiliated to Polymyxa, flagellates, and oomycetes, which suggested that microeukaryotes with various ecological roles, e.g., parasites, bacterial grazers, and decomposers, inhabit the rice rhizosphere. The results showed that the rice root and its growth stages are key factors shaping the microeukaryotic community structure in the rhizosphere.

    The structure and functions of the microbial food web in the rice rhizosphere, the hot spot of methane dynamics in a rice field ecosystem, were studied. Field surveys and pot and microcosm experiments revealed that the rice rhizosphere was inhabited by the specific members of heterotrophic protists (ciliates, flagellates, and amoeba) showing the community shift to the redox conditions and supply of organic matters in the environment. The structure of the microbial food web in the rice rhizosphere that was driven by methane oxidation was also distinct from that of bulk soil.
