DESCRIPTION:Speaker: Dieter Ebert\nAbstract: Parasites are assumed to evolv
 e to optimise their exploitation of hosts\, while hosts\nevolve to minimiz
 e the damage done by the parasite. In coevolutionary models of\nthis proce
 ss high specificity in host parasite interactions are assumed. Furthermore
 \,\ncoevolutionary models make strict assumptions about the underlying gen
 etics. Little\nis known about the genetic interactions between hosts and p
 arasites. In the Daphnia\nsystem this can be conveniently addressed experi
 mentally. Daphnia reproduce\nclonally in the laboratory and clones can be 
 crossed to test for segregation of\nresistance loci. I present experimenta
 l data from our work on the genetics of\nresistance against two parasites 
 of Daphnia magna: the bacterium Pasteuria ramosa\nand the microsporidium H
 amiltosporidium tvaerminnensis. These parasites are\nvirulent and common t
 o D. magna population in Europe. In natural populations\nthese parasites c
 oevolve with their host. Using QTL mapping\, de novo genome\nsequencing an
 d classical breeding experiments\, I present our insights into the\nnature
  of the genetics of antagonistic coevolution.
