1. A potential role for the interaction of Wolbachia surface proteins with the Drosophila microtubulin in maintenance of endosymbiosis and affecting spermiogenesis NSTL国家科技图书文献中心

Mao, Bin |  Wang, Ying-Ying... -  《Journal of Insect Physiology》 - 2025,160 - 共10页

摘要:Wolbachia, as a widely infected intracellular |  symbiotic bacterium in Arthropoda, is able to manipulate |  the reproduction of insect hosts for facilitating |  their own transmission. Cytoplasmic incompatibility |  (CI) is the most common phenotype that Wolbachia

5. Axonemal tubules in the distal sperm tail of Wolbachia‐infected Drosophila simulans males contain ring‐like intraluminal structures that persist after axoneme fragmentation NSTL国家科技图书文献中心

Ambra Pratelli |  Maria Giovanna Ripar...... -  《Cytoskeleton》 - 2025,82(4) - 234~241 - 共8页

摘要:Abstract Wolbachia are obligate intracellular |  alphaproteobacteria that enhance their spreading by altering the |  reproductive mechanisms of several invertebrates. Among the |  reproductive alterations, Wolbachia also causes cytoplasmic |  incompatibility that leads to embryo death when infected males
