Summary: Wheat yield can be limited by both biotic and abiotic factors, with heat stress being a major factor. This study investigated the abundance and diversity of wheat seed endophytic bacteria (WSEB) from heat susceptible and heat tolerant varieties. The results showed higher culturable diversity in the heat susceptible variety and higher heat tolerance in the heat tolerant variety. Metagenomic analysis revealed higher bacterial diversity, with predominant phyla including Proteobacteria, Firmicutes, and Actinobacteria. Understanding the functional characteristics of these bacteria can contribute to improving plant growth and productivity for sustainable agriculture.

Summary: This study analyzed the core microbiome associated with scented and non-scented rice rhizosphere, revealing significant differences in composition and diversity. The analysis also identified distinct and unique microbiota in the rhizosphere of scented rice varieties. Functional gene annotation showed a high abundance of genes related to the biosynthesis of aroma compounds in scented rice. The findings suggest that the specific rhizobacteria identified in this study could be used as bioinoculants to enhance aroma, yield, and sustainable cultivation of rice.

Summary: This study investigated the composition and putative functions of endophytic bacterial communities in ungerminated and germinated seeds of commercial vegetables. The results revealed a high variability in the abundance, diversity, composition, and functionality of endophytic bacteria between ungerminated and germinated seeds in globally commercialized vegetables.

Summary: Black rice is enhanced in growth and antioxidant properties by endophytes such as Enterobacter sp., Kluyvera sp., and Bacillus subtilis, which contain genes for IAA production, phosphate solubilization, siderophore production, colonization, and antioxidant activity. The inoculation of these effective endophytes resulted in significant growth enhancement and increased antioxidant properties in black rice plants. Transcriptome analysis revealed up-regulated genes involved in plant growth, antioxidant properties, interactions, and synthesis of aroma compounds in response to endophytic colonization.

Summary: Endophytic microbiota, including rice endophytes, play a crucial role in promoting plant growth, stress tolerance, and disease control. They enhance host health through the production of phytohormones, solubilized minerals, and by mitigating adverse environmental conditions. Furthermore, endophytes protect plants from phytopathogens and have shown potential applications in environmental waste management and green nanoparticle synthesis.

Summary: Foliar endophytic bacteria and fungi in parasitic and non-parasitic plants were found to be diverse, dominated by generalist taxa, but highly similar across all studied species. Despite contrasting leaf tissue chemistry, the trophic mode of parasitic plants did not systematically affect the diversity, composition, or predicted biogeochemical function of the endophytic microbiomes under field conditions. Parasitic plants may possess mechanisms to regulate the extent of colonization by endophytic fungi.

Summary: The biocontrol strain Pseudomonas alcaliphila Ej2 can effectively help rice plants alleviate the adverse effects of salt stress and promote their growth. The inoculation of Ej2 also influences the endophytic microbiome and proteomic profile of rice, enhancing the plant's ability to tolerate salt stress.

Summary: This study examines the latitudinal diversity gradient (LDG) on the gill and shell-surface microbiomes of the marine bivalve Mytilus californianus. The results show differing diversity patterns in the microbiota of gill and shell surfaces, with individual microbial clades exhibiting different latitudinal trends likely due to varying ecologies and life histories. The study suggests that the diversity decline with increasing latitude may not be a universal pattern across different domains of life.

Summary: This study investigated the microbiota assembly and its relationship with secondary metabolite accumulation in Schisandraceae plants. The results showed that these plants had similar and unique endophytic microbial communities compared to soil microorganisms. Functions associated with metabolic processing were found to be related to the host. Additionally, the accumulation of secondary metabolites was closely related to the endophytic community composition.

Summary: This study found associations of skin microbiota with skin microenvironment, age, body mass index, sex, dietary macronutrients, smoking, alcohol consumption, skin pH, skin type, transepidermal water loss, education and environmental exposures. The skin bacterial community is shaped by the skin microenvironment and host physiology to a greater extent than single skin physiological feature, lifestyle, and environmental exposure.

Summary: A study found that the root symbiotic endophytic fungus and the metabolite B3 can reduce the abundance of pathogenic fungi in rice spikelets, enrich resistant microbes, and inhibit the growth of pathogens and mycotoxin production. This study provides feasibility for controlling disease and toxin contamination in agricultural production by manipulating plant underground tissues to regulate the function of aboveground microbial communities.

Summary: Obesity and cardiometabolic disease are associated with changes in the gut microbiome. Through studying a cohort of 408 adults from Colombia, researchers validated previously reported features of the gut microbiome function and diversity correlated with obesity or poor cardiometabolic health status. The results showed that obesity, rather than metabolic status, is the main driver of differences in gut microbiome functions and structure in individuals with or without poor cardiometabolic health.

Summary: The endophytic actinomycetes Streptomyces hygroscopicus OsiSh-2 has been found to enhance resistance to rice blast while maintaining high yield in 4-year field trials. OsiSh-2 induces defense priming in rice and controls the expression of defense-related proteins, balancing defense and growth to optimize plant performance.
