The origin and mechanism of male-killing, an advantageous strategy employed by maternally transmitted symbionts such as Wolbachia, remain unclear. We compared genomes of four Wolbachia strains derived from Homona magnanima, a male-killing strain wHm-t (1.5 Mb), and three ...

Positive selection and horizontal gene transfer in the genome of a male-killing Wolbachia

T. Hill, R. L. Unckless and J. I. Perlmutter,  Molecular Biology and Evolution,  2021.
Wolbachia are a genus of widespread bacterial endosymbionts in which some strains can hijack or manipulate arthropod host reproduction. Male killing is one such manipulation in which these maternally transmitted bacteria benefit surviving daughters in part by removing competition ...
