Cytoplasmic incompatibility in social insects
In this essay, I briefly summarise reproductive phenotypes associated withWolbachia in insects, present a model of the dynamics of infection frequency for maternally-inherited microorganisms and determine the effect of changing costs associated with incompatibility, infection-related fecundity loss and number of mates in ideal populations of social insects. The model predicts that infections of...
متن کاملPopulation dynamics of the Wolbachia infection causing cytoplasmic incompatibility in Drosophila melanogaster.
Field populations of Drosophila melanogaster are often infected with Wolbachia, a vertically transmitted microorganism. Under laboratory conditions the infection causes partial incompatibility in crosses between infected males and uninfected females. Here we examine factors influencing the distribution of the infection in natural populations. We show that the level of incompatibility under fiel...
متن کاملReduced Expression of BjRCE1 Gene Modulated by Nuclear-Cytoplasmic Incompatibility Alters Auxin Response in Cytoplasmic Male-Sterile Brassica juncea
The signal from organelle to nucleus, namely retrograde regulation of nuclear gene expression, was largely unknown. Due to the nuclear-cytoplasmic incompatibility in cytoplasmic male-sterile (CMS) plants, we employed CMS Brassica juncea to investigate the retrograde regulation of nuclear gene expression in this study. We studied how reduced BjRCE1 gene expression caused by the nuclear-cytoplasm...
متن کاملYou can't keep a good parasite down: evolution of a male-killer suppressor uncovers cytoplasmic incompatibility.
Maternally inherited parasites are known to impose a wide variety of reproductive manipulations upon their host. These often produce strong selection on the host to suppress the parasite, resulting in a reduction in the frequency of the parasite. However, in the butterfly Hypolimnas bolina, infected with a Wolbachia bacterium, field data demonstrate that suppression of the male-killing phenotyp...
متن کاملOn Killing as Causing Death
Common sense has that killing someone amounts to causing the death of someone . This makes killing a physical, biological, or, at best, metaphysical issue, and, as a consequence, the ethics of killing can be dealt with independently of the non-ethical issue of who the killer is . However, in this paper, we show that this is not the case . A physical/biological definition of death plus a metaphy...
