Mapping chromosome rearrangement breakpoints to the physical map of Caenorhabditis elegans by fluorescent in situ hybridization.

abstract：:Mutations in maternally transmitted symbionts can affect host fitness. In this study we investigate a mutation in an obligate bacterial symbiont (Buchnera), which has dramatic effects on the heat tolerance of pea aphid hosts (Acyrthosiphon pisum). The heat-sensitive allele arises through a single base deletion in a ho...
