Recent literature Kim, J. Homology modeling and molecular docking studies of Drosophila and Aedes sex peptide receptors. J Mol Graph Model It is responsible for the reproductive behavior in the Drosophila model system; in particular, it is involved in the post-mating responses such as the increase in egg-laying ability and decrease in receptivity in females. The generated homology models exhibited the typical pattern of inter-helical interactions of reroductive class A GPCRs.
The docking experiments of the small molecule agonist suggest that Tyr5. Additionally, the docking results were found to be consistent with the experimental data of the reference compounds with variable agonistic activities.
Perry, J. Experimental evolution under hyper-promiscuity in Drosophila melanogaster. BMC Evol Biol PubMed ID: Summary: The number of partners that individuals mate with over their lifetime is a defining feature of mating systems, and variation in mate number is thought to be a major driver of sexual evolution.
Although previous research has investigated the evolutionary consequences of reductions in the number of mates, little is known about the costs and benefits of increased numbers of mates. This study uses genetic manipulation of mating frequency in Drosophila melanogaster to create a novel, highly promiscuous mating system. At several time-points during this experimental evolution, examples doodly behavioural, morphological and transcriptional reproductive phenotypes expected to evolve in response to increased population mating frequencies were assayed.
It was found that males from the high mating frequency SPR- populations evolve decreased ability to inhibit the receptivity of their mates and decrease copulation duration, in line with predictions of decreased per-mating investment with increased sperm competition.
Take Notes
Males from SPR- populations initially i. In response to experimentally increased mating frequency, SPR- males evolve behavioural responses consistent with decreased male post-copulatory investment at each mating and decrease overall pre-copulatory performance.
The trend towards increased SP gene expression might plausibly relate to functional differences in the two domains of the SP protein. These data highlight the utility of genetic manipulations of animal social and sexual environments coupled with experimental evolution. Ameku, T.]
