Game of clones: Is Wolbachia inducing speciation in a weevil with a mixed reproductive mode?

Mostrar todas las versiones(2)

Parthenogenesis is widely distributed in Metazoa but it is especially frequent in weevils (Coleoptera, Curculionidae) with one fifth of all known cases. Previous studies have shown that in the tribe Naupactini parthenogenetic reproduction most likely originated with an infection of the endoparasitic...

Naupactini Pantomorus postfasciatus Parthenogenesis Reproductive isolation Speciation Symbiosis Wolbachia infection Parthenogenesis is widely distributed in Metazoa but it is especially frequent in weevils (Coleoptera, Curculionidae) with one fifth of all known cases. Previous studies have shown that in the tribe Naupactini parthenogenetic reproduction most likely originated with an infection of the endoparasitic bacterium Wolbachia pipientis. In particular, Pantomorus postfasciatus possess a mixed reproductive mode: some populations have males while in others they are absent, and females produce clones by thelytoky. To better understand this scenario, we studied the population structure and infection status in 64 individuals of P. postfasciatus from Argentina and Brazil. We sequenced two mitochondrial (COI and COII) and one nuclear (ITS-1) fragments and obtained two very divergent haplogroups, one corresponding to the sexual populations uninfected with Wolbachia, and another conforming a monophyletic parthenogenetic (or presumptively parthenogenetic) and infected clade. Each of these haplogroups was identified as an independently evolutionary unit by all species delimitation analyses accomplished: multilocus *BEAST and BP&P, and single locus GMYC and K/θ rule. Additionally, present evidence suggests that Wolbachia infection occurred at least twice in all-female populations of P. postfasciatus with two different bacterial strains. Speciation mediated by Wolbachia is a recently described phenomenon and the case of P. postfasciatus is the first known case in a diplo-diploid insect. A model that describes how thelytoky-inducing phenotypes of Wolbachia could generate new lineages is discussed. © 2018 Elsevier Inc.
