Summary: Prokaryotic and eukaryotic microbial symbiotic communities exist across different kingdoms, extending the host genome and aiding adaptation to changing environments. Plants and insects carry a variety of microbes on their surfaces, internally, and even within cells, with the insect gut being a selective environment. Despite their high dependence and frequent interaction, it remains uncertain how much plants and insects exchange and modify each other's microbiomes. This review focuses on herbivores that feed on plants in forest ecosystems, discussing the plant microbiome, overlap with insect microbial communities, and the effects of microbiome exchange on each host's fitness.

Summary: The aerial portion of plants, particularly the leaves, are inhabited by pathogenic and non-pathogenic microbes, which interact with the host plant and with each other to form complex microbial communities. Understanding these interactions is crucial for developing biotechnological applications such as plant-protective probiotics.

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: 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.

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: The expression of ACC deaminase by plant-associated bacteria plays a crucial role in modulating plant ACC and ethylene concentrations, overcoming negative effects of inhibitory levels of ACC and ethylene on plant-microbe interactions, growth, and development. Pseudomonas strains with ACC deaminase activity are widely prevalent in the plant microbiome and are of interest for sustainable agricultural and biotechnological solutions. Understanding the properties and actions of ACC deaminase-producing Pseudomonas is key for enhancing plant growth, protecting plants from stress, and promoting rhizobial nodulation.

Summary: Abiotic stress negatively affects plant growth, posing a threat to agriculture and food security. The plant microbiota, which is associated with plants, can enhance plant growth and abiotic stress tolerance, offering potential for increased crop production. This review summarizes recent progress on the impact of abiotic stress on plants, microbiota, and plant-microbe interactions, as well as the utilization of plant microbiota in agriculture under abiotic stress conditions.

Summary: Plants have developed various mechanisms to respond to abiotic stress and plant-microbe interactions, which can be either harmful or beneficial. Cyclophilins are proteins involved in these responses, with diverse functions in different cellular compartments and processes.Understanding the role of cyclophilins in plant defense and symbiotic interactions with microbes is important for improving crop productivity and quality.

Summary: The plant cell wall plays important roles in plant-microbe interactions, including physical defense, storage of antimicrobial compounds, production of cell wall-derived elicitors, and provision of carbon sources. Additionally, we discuss four families of cell surface receptors associated with plant cell walls that have been the subject of important studies in recent years, providing valuable insights into plant cell wall and immunity.

Summary: This article reviews the interaction between non-isothiocyanate products derived from the glucosinolate pathway and fungi. These products include glucosinolates and their precursors, glucosinolate-derived nitriles, thiocyanates, epithionitriles, and oxazolidine-2-thiones, putative isothiocyanate downstream products, and indole phytoalexins. The article provides a literature review on their antifungal activity, increased biosynthesis after fungal challenge, and their biotransformation/detoxification by fungi, including myrosinase activity.

Summary: This study explored the differences in gut microbiome and differentially expressed genes related to lipid metabolism and the immune system in the donkey hindgut. The study found significant differences in dominant bacteria among different sections of the hindgut, particularly between the cecum and dorsal colon sites. It also identified interesting DEGs related to lipid metabolism and the immune system, with the PPAR pathway being mainly enriched in the cecum. Furthermore, the study revealed a complex relationship between the gut microbiome and gene expression, especially in relation to the immune system.

Summary: Plants adapt their metabolism to stress-induced energy deficiency by undergoing significant changes in amino acid metabolism. Amino acids can act as alternative substrates for respiratory pathways and also as signaling molecules in response to stress. The regulation of amino acid metabolism during energy deprivation is controlled by the balance between TOR and SnRK signaling, with some amino acids potentially serving as nutrient signals to promote a shift from catabolic to anabolic pathways.

Summary: During drought stress, decreased photosynthesis leads to protein degradation and an increase in free amino acid content. The released amino acids are mostly converted into proline for osmolyte synthesis, while the remaining amino acids can be oxidized as an alternative respiratory substrate.
