Cardinium symbionts cause cytoplasmic incompatibility in spider mites

Article Abstract:

16S ribosomal DNA sequences similar to those of Cardinium from seven populations of five spider mite species are detected suggesting a broad distribution of infection of Cardinium in spider mites. Tetranychus pueraricola, specie of spider mite was found to harbor both Cardinium and Wolbachia, but these symbionts seemed to have no effect on the reproduction of the host, even when the host was infected independently with each symbiont.

Wolbachia and nuclear-nuclear interactions contribute to reproductive incompatibility in the spider mite Panonychus mori (Acari: Tetranychidae)

Article Abstract:

The relationship between Wolbachia infection and reproductive incompatibility among populations of Panonychus mori is examined. Wolbachia infection caused incompatibility between uninfected females and infected males or between females and males harboring different Wolbachia strains whereas nuclear-nuclear interactions resulted in bidirectional incompatibility in 99 combinations of interpopulation crosses.
