Abstract: | Background Bacterial symbioses are widespread among insects. The early establishment of such symbiotic associations has probably been
one of the key factors for the evolutionary success of insects, since it may have allowed access to novel ecological niches
and to new imbalanced food resources, such as plant sap or blood. Several genomes of bacterial endosymbionts of different
insect species have been recently sequenced, and their biology has been extensively studied. Recently, the complete genome
sequence of Candidatus Carsonella ruddii, considered the primary endosymbiont of the psyllid Pachpsylla venusta, has been published. This genome consists of a circular chromosome of 159,662 bp and has been proposed as the smallest bacterial
endosymbiont genome known to date. |
