Summary: Our study developed a three-dimensional live microscopy technique to observe plant-microbe interactions in transparent soil, providing valuable insights into the colonization patterns of Bacillus subtilis populations in the rhizosphere of lettuce plants. This innovative system allows for real-time tracking of microbial movement and is a powerful tool for understanding complex interactions in the environment.

Summary: The root and rhizosphere interactions play a crucial role in plant fitness, soil health, and carbon cycling underground. Understanding the molecular mechanisms behind these interactions can help design sustainable ecosystems in the future. Developing new technologies, like the 3D root cartography platform, can provide a better visualization of the molecular and microbial constituents in the root-rhizosphere zone.

Summary: This comprehensive review discusses the multiple roles of flavonoids in mediating plant-microbe interactions, including their synthesis, transport, and exudation in plants, the importance of flavonoids in regulating plant-microbe interactions, and how flavonoids influence the overall community assembly of plant-root microbiomes. The review also highlights potential knowledge gaps in understanding how flavonoids determine the interactions between plants and commensal microbes, advocating for further research in this area for innovative strategies to manipulate plant-microbiome composition.

Summary: Plant growth-promoting rhizobacteria (PGPR) play a crucial role in promoting plant growth and health through various mechanisms, including modulating root zone microbial community and soil functionality. However, the underlying mechanisms of PGPR's positive effects are not well understood and further ecological research is needed.

Summary: Beneficial microbial communities in the rhizosphere play a crucial role in plant-pathogen interactions by acting as a barrier to pathogen invasion and inducing plant systemic resistance. Plants can manipulate and recruit beneficial microbes, shaping their rhizosphere microorganisms in response to pathogen invasion. This reciprocal symbiosis between plants and beneficial microbes helps increase plant growth and productivity while avoiding excessive immune responses.

Summary: Plant root exudation is a crucial means of communication between plants and soil microbes, impacting rhizosphere processes and ecosystem responses to changing environmental conditions. Differences in root exudate quantity and quality among plant species are influenced by plant functional group and traits such as root diameter, root tissue density, and root nitrogen content. Higher rates of root exudation were linked to traits indicative of exploitative growth and resource outsourcing, providing insights into species-specific differences and the role of root exudates in the resource-outsourcing strategy.

Summary: Plant-microbe interactions are crucial for ecosystem functioning and root exudates play a key role in communication between plants and microbes. Hybrid root exudate collection methods offer an ecologically relevant alternative, but a recovery period after root washing is critical to prevent bias. The hybrid method yields exudates that discriminate between species and provide a diverse metabolome for better identification of metabolites.

Summary: This article discusses the importance of controlled environment agriculture (CEA) systems as a backup support for future resource consumption and potential food crises as natural agroecology deteriorates. Due to the dependency and fragility of CEA systems, proper water management is crucial for constructing a stable rhizosphere microenvironment.

Summary: Terrestrial plants can influence the recruitment of rhizosphere microbiome in adjacent plants through root exudates, potentially affecting their growth and health. This study demonstrated that intercropping with potatoonion can create a disease-suppressive rhizosphere microbiome that protects tomato plants against Verticillium wilt disease. The root exudates from potatoonion promoted the colonization of Bacillus sp., which inhibited the growth of the pathogen and induced resistance in tomato plants.

Summary: Plants can recruit beneficial microbes to improve their fitness under stress, and Panax notoginseng has been found to enrich a beneficial bacterium, Burkholderia sp. B36, under autotoxic ginsenoside stress. The stress activates root pathways and increases the secretion of specific metabolites that promote the growth of B36. Importantly, one of these metabolites, cinnamic acid, also enhances the colonization of B36 in the rhizosphere and increases the survival rate of P. notoginseng.

Summary: Progress in understanding allelopathic interactions among plants has been limited by the complexity of direct and indirect interactions, as well as the influence of various factors such as resource limitations, pathogens, and herbivores. Recent advancements in technology and analytical techniques have allowed researchers to study the biosynthesis of allelochemicals and plant responses in more detail. This review highlights the importance of applying these new approaches in ecologically rigorous ways to enhance our understanding of allelopathic interactions.
