WebThis is because Wolbachia causes cytoplasmic incompatibility (CI), a phenomenon where sperm and eggs are unable to form viable offspring. Scientists are still trying to understand how Wolbachia causes … Cytoplasmic incompatibility (CI) is a phenomenon that results in sperm and eggs being unable to form viable offspring. The effect arises from changes in the gamete cells caused by intracellular parasites like Wolbachia, which infect a wide range of insect species. As the reproductive incompatibility is … See more CI occurs when a Wolbachia infected male mates with a female that is infected by another Wolbachia strain (bidirectional CI) or is uninfected (unidirectional CI). Any other combination of un-/infected male/female … See more CI, as described by Werren, results in selection pressure on uninfected males, as infected females can mate both with uninfected males … See more • Wolbachia • Cardinium • Endosymbiont • Intragenomic conflict See more There are two distinguished events that lead to the CI inducing manipulation. The first occurs inside the Wolbachia infected male during spermatogenesis and is called modification. Because Wolbachia are absent from mature sperm and appear to be excluded during … See more Wolbachia are not the only bacteria capable of inducing CI. For example, researchers have found that infection by bacteria of the genus Cardinium can also result in CI. See more

WebNov 21, 2024 · Abstract Cytoplasmic incompatibility (CI) is an intriguing, widespread, symbiont-induced reproductive failure that decreases offspring production of arthropods through crossing incompatibility of infected males with uninfected females or with females infected with a distinct symbiont genotype. WebMar 3, 2024 · Abstract Wolbachia are maternally transmitted, intracellular bacteria that can often selfishly spread through arthropod populations via cytoplasmic incompatibility (CI). CI manifests as embryonic death when males expressing prophage WO genes cifA and cifB mate with uninfected females or females harboring an incompatible Wolbachia strain.
