Summary: Root-microbiome interactions play a crucial role in plant performance and yield, particularly in legumes which engage in symbiosis with N-2-fixing rhizobia. The rhizobial symbiotic capacity was found to significantly alter root-associated microbiomes by impacting diversity, co-occurrence interactions, and microbial depletion in the rhizosphere and rhizoplane. Root exudates and soil physiochemical properties were closely correlated with microbial community shifts in response to different rhizobial treatments.

Summary: A study in Arabidopsis identified the important role of folate in plant root development. The folb2 mutant showed severe defects in primary root development, with impaired root apical meristem and frequent adventitious roots. The mutation in the AtFolB2 gene, involved in folate biosynthesis, resulted in reduced folate content and knockdown lines phenocopied the mutant. Folate was found to promote auxin transport and affect auxin-related proteins and response factors, providing insights into its role in shaping root structure.

Summary: The study found that sorgoleone can influence belowground microbial community structure in the field, as well as impact bacterial growth and nitrification, particularly in soil near roots and rhizosphere. Under greenhouse conditions, soil nitrogen content was a key factor in determining the effects of sorgoleone.

Summary: Mucilage and extracellular polymeric substances (EPS) share similar physical and chemical properties, both serving as biofilm matrices in the rhizosphere. Mucilage functions as a carbon and nutrient source, promoting high microbial abundance and activity in the rhizosphere. The importance of mucilage as a microbial habitat has been underestimated.

Summary: Plant-soil feedbacks mediated by benzoxazinoids (BXs) were found to affect maize growth and insect resistance conservatively in two arable soils, but not in a more fertile grassland soil, indicating a soil-type dependence. Wheat also responded to BX-feedbacks, showing a negative growth response conserved between cereals, while insect resistance exhibited opposite patterns. Cultivar-specificity of BX-feedbacks was a key finding, suggesting the potential to optimize crops to avoid negative plant-soil feedbacks in rotations.

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: The functional traits of bacterial root endophytes can predict their impact on plant growth. This study isolated 183 bacterial endophytes from two tomato species and screened them for six functional traits. The isolates were then grouped based on their traits, and it was found that isolates within the same functional group promoted plant growth at similar levels, regardless of their host origin or taxonomy.

Summary: This study investigated the occurrence and distribution of antibiotic resistance genes (ARGs) across the soil-plant interface using Sedum alfredii as a model plant. The results showed significant shifts in ARGs between rhizosphere and bulk soils, which were associated with variations in bacterial functions. These findings contribute to our understanding of the mechanism underlying the transmission of ARGs from bulk soils to rhizosphere soils.

Summary: Kiwifruit Vine Decline Syndrome (KVDS) is a soil-borne disease that causes economic losses in the Italian kiwifruit industry. This study found that different Actinidia genotypes showed varying levels of resistance to KVDS, and the presence of different oomycetes in the plant rhizosphere and endosphere correlated with the symptoms displayed. Actinidia macrosperma was found to have resistance to KVDS due to its ability to shape the pathobiome.

Summary: This study explored the interaction between plant genetics and microbiomes using 100 tea plant cultivars. The results showed that diverse host factors play a role in driving microbial variation in plant-associated environments. The genetic mechanisms behind this phenomenon were found to be compartment-specific, with certain genes associated with specific microbial compositions in different plant compartments.

Summary: Plants recruit beneficial microbes while excluding pathogens by using metabolites and integrating multiple inputs to initiate immunity or mutualistic symbiosis. The plant immune thermostat is set to select for and tolerate a largely non-harmful microbiome, while receptor-mediated decision making allows plants to detect and dynamically respond to potential pathogens or mutualists.

Summary: The use of genetically tractable plant-microbe pairs has significantly advanced research in plant immunity and mutualistic symbiosis. However, the complexity of the microbiome and its subtle effects on plant growth and immunity have hindered forward genetic screening to identify genes shaping the microbiome. Research in microbiome has largely relied on reverse genetics approaches based on plant nutrient uptake and immunity knowledge.

Summary: Research has shown that different fluorescent pseudomonads have varying effects on fungal growth, with Pseudomonas protegens CHA0 exhibiting the strongest inhibitory potential. Fungal morphology and transcriptome are altered during co-cultivation with pseudomonads, and the bacterial effect on the pathogen contributes to plant protection.

Summary: Plants form commensal associations with soil microorganisms, creating a root microbiome that provides protection against pathogens. However, the mechanisms of how microbiota contribute to pathogen protection are still unclear. By studying a model system of plant-pathogen-microbiome interactions, researchers discovered that commensal strains closely related to the pathogen were more likely to protect against pathogenesis. They also found that commensal colonization level was highly predictive of protection and identified genes involved in membrane modifications that are required for pathogen protection. These findings provide insights into the mechanisms of host protection by microbiota and have implications for microbiome engineering in dysbiotic soil systems.

Summary: Understanding how microbiota evade and suppress host immunity is critical to our knowledge of how beneficial microbes persist in association with a host. This work shows that microbial amino acid metabolism is not only critical for growth in the plant rhizosphere microbiome, but also for regulation of plant rhizosphere pH, and, consequentially, regulation of plant immunity.
