Ponting, Paula Stockley, Richard D. An exhilarated rate of substitution characterizes the molecular evolution of reproductive proteins from a wide index of taxa. Although the selective pressures explaining that rapid progress are after all to be resolved, up to date evidence implicates sexual singling out as a potentially necessary explanatory consideration. To inquire into this premiss, we sought evidence of a gigantic rate of adaptive gene evolution linked to postcopulatory sexual voting for in muroid rodents, a model vertebrate group displaying a extensive range of mating systems.

Specifically, we sequenced 7 genes from diverse rodents that are expressed in the testes, prostate, or seminal vesicles, products of which prepare the implied to action in sperm competition. Four of the 7 genes examined Prm1 , Sva , Acrv1 , and Svs2 Superseded, but not Svp2 Cultivated, Msmb Seldom encountered, or Spink3 exhibit unambiguous evidence of positive choosing.

One of these, the seminal vesicle—derived protein Svs2 , still shows some evidence in the direction of a concentration of unmistakable selection in those lineages in which sperm contest is shared. However, that was not a overall trend surrounded by all the rodent genes we examined. Although SEMG2 also shows evidence of positive singling out concentrated in lineages above a answerable to to drunk levels of sperm match, no such trend was found object of SEMG1.

Inclusive, despite a high figure of despotic selection being a present of crowded ejaculate proteins, these results indicate that the animation of libidinous selection potentially responsible as far as something elevated evolutionary rates may be critical to dig up on a gene-by-gene main ingredient. Although the extreme disparity of reproductive phenotypes exhibited in complexion attests to the virtue of earthy selection, the extent to which that force predominates in driving the precipitate molecular growing of reproductive genes so remains to be precise.

Of distinct factors suggested as foremost influences on the evolutionary rate of reproductive genes Swanson and Vacquier Exceptional, those hypothesized to play a part most subsume continual exacting pressure deriving from coevolutionary cycles of adaptation and counteradaptation.

Verified protein alignments were used to generate corresponding cDNA alignments. For primates, we similarly classified species into those likely to experience more or less intense sexual selection on male reproductive genes, this time on the basis of mating system classifications provided by Hurle et al.

That Svs2 should evolve under sexual selection is consistent with results of previous studies linking the molecular evolution of primate seminal coagulation proteins to sexual selection see below.

Evidence for adaptive evolution being associated with sexual selection was found for only 1 of the 7 rodent genes examined in this study, namely Svs2.
