Summary: The chemical interactions between fungal endophytes and plant leaves are likely to be the key mechanism affecting plant phenotypic traits. This study found that multiple fungal strains share functional similarities in their effects on plant growth and physiology under unstressed conditions. Plant metabolomics profiles were correlated with fungal treatments, and specific metabolites were associated with plant trait variation. These findings have implications for the development of metabolites as crop management tools.

Summary: Two new nucleoside derivatives, kipukasins O (1) and P (2), one new cyclohexenone derivative, arthropsadiol D (5), and one new natural product, (+)-2,5-dimethyl-3(2H)-benzofuranone (6), were isolated from the culture broth of the endophytic fungus Aspergillus polyporicola R2. The absolute configuration of compound 5 was determined and the antimicrobial activities of these compounds were evaluated.

Summary: Plant secondary metabolites have potential applications in various industries, but their direct isolation from plants may lead to over-harvesting and loss of biodiversity. Endophytic microbes have the ability to produce metabolites similar to those of their host plants, providing a sustainable and commercially valuable resource.

Summary: The exploration of cadmium activation mechanisms mediated by the rhizosphere process is crucial for understanding the accumulation of cadmium in plants. This study investigated the responses of two oilseed rape cultivars with different cadmium accumulation traits to cadmium stress using metabolome and microbiome analyses. The results revealed that the differences in shoot cadmium accumulation between the two cultivars were attributed to the rhizosphere processes, which were influenced by pH, cadmium mobility, and the secretion of certain organic acids. Bacterial taxa with cadmium-resistant and activation capacities were also found to be enriched in the rhizosphere of one of the cultivars. These findings provide important insights into the cultivar response to cadmium accumulation and can contribute to the cleaner production of oilseed rape.

Summary: The tradeoff between facilitation and competition in a maize-grass pea intercropping system was found to be driven by rhizospheric interactions, and the intensity and type of interaction varied depending on resource availability. Positive plant-plant interactions were observed under all environmental conditions, with higher total yield and biomass net effect. Maize growth was consistently facilitated, while the facilitation of grass pea yield and biomass shifted with different stressors, such as low soil P and moisture conditions.

Summary: Bacterial communities associated with the rhizosphere and roots of the long-sepal Donggang pasque-flower (DPF) plant were investigated, revealing differences between wild and cultivated plants. The core bacterial microbiota commonly functioned as endophytes in both wild and cultivated DPF plants, providing benefits through nitrogen fixation, phosphate solubilization, and phytohormone production.

Summary: This study investigates the characteristics of selenium accumulation in Cardamine hupingshanensis at different growth stages, and reveals the correlations between rhizobacteria and endophytes with selenium hyperaccumulation. The results show that leaves exhibit the highest selenium levels and rhizobacterial diversity is positively correlated with soil selenium contents. Low-abundance bacteria are identified to potentially increase the bioavailable selenium levels in the rhizosphere.

Summary: The microbiome of grafted grapevine root systems is largely influenced by the combination of rootstock and scion, which affects the microbial diversity uptaken from soil. The bacterial and fungal communities associated with different rootstock-scion combinations play a significant role in shaping the microbiome, indicating that the relative abundance of microbiome members is a key factor in determining microbiome differences among combinations.

Summary: Beneficial interactions between endophytes and plants are crucial for plant growth and metabolite accumulation. Plant-derived triterpenoids were found to promote the growth of endophytic bacteria and fungi, which in turn enhanced host plant growth and secondary metabolite productions. This study suggests a strategy for constructing synthetic communities (SynComs) based on the screening of secondary metabolites, where bacteria and fungi work together to promote plant health.

Summary: In this study, two antimicrobial peptides (CgR2150 and CgR3101) with broad-spectrum antibacterial activities were identified from endophytes isolated from potato tubers. These peptides showed excellent stability and could significantly inhibit the growth of various bacteria and fungi. Scanning electron microscopy revealed that these peptides disrupt bacterial cell membranes. The findings suggest that CgR2150 and CgR3101 have potential as new antibacterial agents.

Summary: Phytoremediation of petroleum hydrocarbons in subarctic regions is challenging due to extreme climate, limited nutrients, and remote locations. A long-term experiment in Alaska showed that the original type of contaminated soil and phytoremediation strategy influenced the structure of microbial communities associated with colonizing plants even 20 years after the treatments. This study provides new insight into the long-term succession of soil and plant-associated microbiota in subarctic areas contaminated by PHCs and highlights the importance of restoration strategies in influencing plant-associated microbiota.
