چکیده
"Candidatus Portiera aleyrodidarum" is the obligate primary endosymbiotic bacterium of whiteflies, including the sweet potato whitefly Bemisia tabaci, and provides essential nutrients to its host. Here we report two complete genome sequences of this bacterium from the B and Q biotypes of B. tabaci.

Genome Evolution in the Primary Endosymbiont of Whiteflies Sheds Light on Their Divergence
Whiteflies are important agricultural insect pests, whose evolutionary success is related to a long-term association with a bacterial endosymbiont, Candidatus Portiera aleyrodidarum. To completely characterize this endosymbiont clade, we sequenced the genomes of three new Portiera strains covering the two extant whitefly subfamilies. Using endosymbiont and mitochondrial sequences we estimated t...
متن کاملBiotype-dependent secondary symbiont communities in sympatric populations of Bemisia tabaci.
The sweet potato whitefly, Bemisia tabaci, harbors Portiera aleyrodidarum, an obligatory symbiotic bacterium, as well as several secondary symbionts including Rickettsia, Hamiltonella, Wolbachia, Arsenophonus, Cardinium and Fritschea, the function of which is unknown. Bemisia tabaci is a species complex composed of numerous biotypes, which may differ from each other both genetically and biologi...

Endosymbionts are vital factor for arthropod ecology. The whitefly Bemisia tabaci (Hemiptera: Aleyrodidae) is a cryptic species complex composed of more than 34 putative species. Moreover to the primary endosymbiont Portiera aleyrodidarum, six secondary endosymbionts Cardinium, Arsenophonus, Rickettsia, Wolbachia, Hamiltonella and Fritschea are known in B. tabaci. Here, we tested four of the si...
متن کاملEvidence for Horizontal Transmission of Secondary Endosymbionts in the Bemisia tabaci Cryptic Species Complex
Bemisia tabaci (Hemiptera: Aleyrodidae) is a globally distributed pest composed of at least 34 morphologically indistinguishable cryptic species. At least seven species of endosymbiont have been found infecting some or all members of the complex. The origin(s) of the associations between specific endosymbionts and their whitefly hosts is unknown. Infection is normally vertical, but horizontal t...
متن کاملRelative amount of symbionts in Bemisia tabaci (Gennadius) Q changes with host plant and establishing the method of analyzing free amino acid in B. tabaci
The impact of symbionts on their insect hosts depends on their infection density. In the current study, we investigated the effects of host plants (cucumber, cabbage, and cotton) on the relative amount of symbionts Portiera and Hamiltonella in the whitefly Bemisia tabaci (Gennadius) Q. The relative amounts of symbionts in 3 host plant B. tabaci Q populations with the same genetic background wer...
