Phylogeographic support for horizontal gene transfer involving sympatric bruchid species
Abstract Background We report on the probable horizontal transfer of a mitochondrial gene, cytb, between species of Neotropical bruchid beetles, in a zone where these species are sympatric.The bruchid beetles Acanthoscelides obtectus, A.obvelatus, A.argillaceus and Zabrotes subfasciatus develop on various bean species in Mexico.Whereas A.obtectus a
