I. Tamas ; L. Klasson ; B. Canback ; A. Naslund ; A. Eriksson ; J. Wernegreen ; J. Sandstrom ; N. Moran ; S. Andersson | 2002Comparison of two fully sequenced genomes of Buchnera aphidicola, the obligate endosymbionts of aphids, reveals the most extreme genome stability to date: no chromosome rearrangements or gene acquisitions have occurred in the past 50 to 70 milli[...]

N. Moran ; P. Baumann | 2000Molecular phylogenetic studies reveal that many endosymbioses between bacteria and invertebrate hosts result from ancient infections followed by strict vertical transmission within host lineages, Endosymbionts display a distinctive constellation[...]

J. Wernegreen ; N. Moran | 1999Buchnera, the bacterial endosymbionts of aphids, undergo severe population bottlenecks during maternal transmission through their hosts. Previous studies suggest an increased effect of drift within these strictly asexual, small populations, resu[...]

A. Telang ; J. Sandstrom ; E. Dyreson ; N. Moran | 1999The feeding behavior of Diuraphis noxia Mordvilko (Homoptera: Aphididae) on susceptible hosts causes both ultrastructural and tissue level damage which may affect phloem composition. Genetic evidence suggests that endosymbiotic bacteria in most [...]

J. Sandstrom ; J. Russell ; J. White ; N. Moran | 2001Many insect groups have obligate associations with primary endosymbionts: mutualistic bacteria that are maternally transmitted and derived from an ancient infection. Often, the same insects are hosts to 'secondary' bacterial symbionts which are [...]

J. Sandstrom ; A. Telang ; N. Moran | 190Three aphid species were compared with respect to ability of enhancing the nutritional quality of their host plants. Rhopalosiphum padi, which does not induce macroscopic changes in its host plants, was compared with Schizaphis graminum and Diur[...]

N. Moran | 2001Insects that feed on plant sap depend on symbiotic bacteria for nutrients that are not present in the diet. These bacteria live within host cells and are transmitted from mother to offspring. The symbionts of aphids, in the genus Buchnera, are t[...]
