WebCytoplasmic incompatibility (CI) (i.e., sperm-egg incompatibility) is the most common drive system of Wolbachia (O’Neill et al., 1997; Werren et al., 2008). The molecular basis of CI … 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 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 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. … 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
