An ancient but promiscuous host-symbiont association between Burkholderia gut symbionts and their heteropteran hosts.

ABSTRACT: Here, we investigated 124 stinkbug species representing 20 families and 5 superfamilies for their Burkholderia gut symbionts, of which 39 species representing 6 families of the superfamilies Lygaeoidea and Coreoidea were Burkholderia-positive. Diagnostic PCR surveys revealed high frequencies of Burkholderia infection in natural populations of the stinkbugs, and substantial absence of vertical transmission of Burkholderia infection to their eggs. In situ hybridization confirmed localization of the Burkholderia in their midgut crypts. In the lygaeoid and coreoid stinkbugs, development of midgut crypts in their alimentary tract was coincident with the Burkholderia infection, suggesting that the specialized morphological configuration is pivotal for establishment and maintenance of the symbiot
