| cytoplasmic incompatibility in drosophila simulans: dynamics and parameter estimates from natural populations. | in drosophila simulans, cytoplasmically transmitted wolbachia microbes cause reduced egg hatch when infected males mate with uninfected females. a wolbachia infection and an associated mtdna variant have spread northward through california since 1986. pcr assays show that wolbachia infection is prevalent throughout the continental us and central and south america, but some lines from florida and ecuador that are pcr-positive for wolbachia do not cause incompatibility. we estimate from natural po ... | 1995 | 7498773 |
| dynamics of double and single wolbachia infections in drosophila simulans from new caledonia. | the bacterial symbiont wolbachia can cause cytoplasmic incompatibility in drosophila simulans flies: if an infected male mates with an uninfected female, or a female with a different strain of wolbachia, there can be a dramatic reduction in the number of viable eggs produced. here we explore the dynamics associated with double and single wolbachia infections in new caledonia. doubly infected females were compatible with all males in the population, explaining the high proportion of doubly infect ... | 2002 | 11920119 |
| comparative genomics of wolbachia and the bacterial species concept. | the importance of host-specialization to speciation processes in obligate host-associated bacteria is well known, as is also the ability of recombination to generate cohesion in bacterial populations. however, whether divergent strains of highly recombining intracellular bacteria, such as wolbachia, can maintain their genetic distinctness when infecting the same host is not known. we first developed a protocol for the genome sequencing of uncultivable endosymbionts. using this method, we have se ... | 2013 | 23593012 |
