Selection by parasites may increase host recombination frequency

Abstract: Meiotic recombination destroys successful genotypes and it is therefore thought to evolve only under a very limited set of conditions. Here, we experimentally show that recombination rates across two linkage groups of the host, the red flour beetle Tribolium castaneum, increase with exposure to the microsporidian parasite, Nosema whitei, particularly when parasites were allowed to coevolve with their hosts. Selection by randomly varied parasites resulted in smaller effects, while directional selection for inse… Show more

“…Tribolium castaneum is known to naturally harbour a range of protozoan and other parasites ( West 1958( West , 1960Sokoloff 1974;Padin et al 2002;Blaser & Schmid-Hempel 2005;Fischer & Schmid-Hempel 2005). These beetles, nowadays mainly living in mills, grain stores and bird nests, are very likely to be exposed repeatedly to similar infections.…”

“…Recently, T. castaneum has been further developed into a model system for embryonic development and pesticide resistance (Lorenzen et al 2005;, population genetics (Zhong et al 2004;Demuth & Wade 2007), mate choice (Bernasconi & Keller 2001;Pai & Yan 2002;Pai et al 2007;Pai & Bernasconi 2008) and for the study of host-parasite coevolution (Pai & Yan 2003;Fischer & Schmid-Hempel 2005). As its genome sequence has been completed, it is likely that other fields of biology will adopt this model system as well (Richards et al 2008; http://www.hgsc.bcm.tmc.edu/projects/tribolium/ ).…”

“…Therefore, these processes are predicted to lead to the continuous generation of novel genotypes to which the respective antagonist is not adapted (5,9,10). Furthermore, the spread of new favorable alleles is predicted to cause an at least temporary increase in genetic diversity within the population (11).…”

“…Several previous coevolution experiments also focused on multicellular hosts, which are characterized by more complex defense responses than microbes. These experiments were performed under laboratory and field conditions and included Drosophila fruit flies, the red flour beetle Tribolium castaneum, the waterflea D. magna, and different snail species (6,9,(22)(23)(24)(25). Particular studies in these host systems usually focused on only one set of predictions in only one of the antagonists, such as host resistance and associated tradeoffs in Drosophila flies (6) or infectivity of the bacterial parasite of D. magna (22).…”
