Summary: Wolbachia, as the most widespread intracellular bacteria in the animal kingdom, serves as a biological archetype for studying symbiosis and its applications in combating human and agricultural diseases. Through a comprehensive analysis, Wolbachia's host range, diversity, genomics, cell biology, applications, and the mobilome including phage WO have been synthesized, highlighting its essentiality to reproductive phenotypes in arthropods. The interdisciplinary science of Wolbachia symbiosis also serves as a model for teaching integrative rules of endosymbiotic life.

Summary: This study suggests that the coevolutionary relationships between chewing lice, endosymbiotic bacteria, and birds are not independent, but the patterns vary depending on the analysis method used. Additionally, louse host-switching does not seem to affect bacterial strains.

Summary: This study investigated the degradation of chlorpyriphos and polyethylene by Citrus mealy bug bacterial endosymbionts, which showed significant reductions in weight of polyethylene and tensile strength after treatment. The bacterial isolates, especially B. cereus and P. putida, were found to be most effective in reducing the total amount of chlorpyriphos in soil. The results suggest that endosymbionts play a significant role in degrading chlorpyriphos and polyethylene from the environment.

Summary: The bacterial assemblages within Microcystis colonies show resilience to environmental perturbations, while the Microcystis population is significantly promoted by nitrogen and temperature. Community diversity is inversely correlated with the intensity of Microcystis blooms. The predicted abundance of metabolic genes is less impacted by environmental drivers.

Summary: The study found that vertical and horizontal transmission of ToSRV by B. tabaci MEAM1 is unlikely. Therefore, sustainable management of tomato golden mosaic disease caused by ToSRV should continue to focus on using resistant varieties, managing sources of inoculum around tomato fields, and rational chemical control of the vector.

Summary: The structure and symbiotic system of the ground mealybug, Rhizoecus albidus, were studied using microscopic and molecular methods. The ovaries of R. albidus consist of multiple ovarioles, each containing germ cells and bacterial cells. These bacteria are transmitted vertically to the next generation. These findings support the recent classification changes of ground mealybugs.

Summary: Tomato yellow leaf curl viruses are causing disease outbreaks in tomato crops in tropical and subtropical regions globally. Sweet potato whitefly is the vector of this group of viruses. This research focused on the transmission biology of tomato yellow leaf curl Thailand virus (TYLCTHV) by Bemisia tabaci, revealing the virus translocation within the whitefly without replication and lack of evidence for transovarial transmission.

Summary: Wolbachia is being developed as a biological tool to suppress mosquito populations and interfere with their transmitted viruses. Previous studies have shown that mosquitoes infected with three strains of Wolbachia can almost completely block the transmission of dengue virus and Zika virus. This study found that Wolbachia can inhibit the transmission of Zika virus in the ovaries of mosquitoes, and there is a negative correlation between Wolbachia density and virus load.

Summary: This study found that Ophiocordyceps fungi may be obligate symbionts of certain sap-sucking hemipterans, confirmed through histological, ultrastructural, and molecular analyses. The essential role of these fungal symbionts in the biology of soft scale insects was highlighted, with evidence of transmission between generations through transovarial transmission observed.

Summary: Bemisia tabaci, a harmful agricultural insect pest and vector of plant viruses, has different cryptic species with varying resistance to insecticides. In this study, the genetic variation and infection profile of whitefly populations from India were analyzed. The major cryptic species identified was Asia I, while different populations showed varying levels of resistance to thiamethoxam, imidacloprid, and acetamiprid insecticides. The study also revealed the presence of different symbiotic bacteria in the whitefly populations, with Arsenophonus being the most dominant. The findings suggest that a symbiont-oriented management program could be effective in controlling whitefly resistance and reducing pesticide use in agriculture.

Summary: In this study, we observed autogenous reproduction of Ornithodoros turicata ticks and found that they can transmit Borrelia turicatae to their offspring. These findings are significant for understanding the reproductive biology of O. turicata and the interactions between spirochetes and ticks.

Summary: The research team has developed a self-assembling cellular coating to improve the viability and stability of the next-generation biotherapeutic Bacteroides thetaiotaomicron, providing protection from harsh processing conditions and oxygen exposure. This advancement will increase the range of stably manufactured microbes, facilitating the development of emerging strains of interest by ensuring their postproduction viability.

Summary: Researchers tested the potential of artificial endosymbiosis in mammalian cells, and found that the growth rate of E. coli within the cell can be slowed down by limiting the uptake of aromatic amino acids, prolonging the survival of the endosymbiont-host pair.

Summary: Studying endosymbiosis is crucial for understanding cellular evolution and engineering. By injecting different bacteria into mammalian cells, we tested their potential for endosymbiosis and found that limiting the uptake of specific nutrients can slow down the intracellular growth of the endosymbiont.
