Description:Comparative genomics from mitochondria\, plastids\, and mutuali
 stic endosymbiotic bacteria has shown that the stable establishment of a b
 acterium in a host cell results in genome reduction. Although many highly 
 reduced genomes from endosymbiotic bacteria are stable in gene content and
  genome structure\, organelle genomes are sometimes characterized by drama
 tic structural diversity. Previous results from Hodgkinia\, an endosymbion
 t of cicadas\, revealed that some lineages of this bacterium had split int
 o multiple new cytologically distinct yet genetically interdependent speci
 es. In this talk I will outline the diversity of Hodgkinia genomes we have
  discovered\, and show how these processes both parallel and differ from s
 ome examples of genome fragmentation and expansion in organelles. 4:00 pm
