Proteome analysis of male accessory gland secretions in the diamondback moth, Plutella xylostella (Lepidoptera: Plutellidae)

ABSTRACT: In insects, male accessory gland proteins (ACPs) are important reproductive proteins secreted by male accessory glands (MAGs) of the internal male reproductive system. During mating, ACPs were transferred along with sperms inside female bodies and have a significant impact on the physiology of female reproduction. Under sexual selection pressures, the ACPs exhibit remarkably rapid and divergent evolution and varies from species to species. The diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), is a major insect pest of cruciferous vegetables worldwide. The reproductive physiology on post-mating state of this species is still largely unknown, which is important for management of this pest. In this study, the ACPs transferred into females during mating were identified by using a tandem mass tags quantitative proteomic analysis. The MAGs were compared before and after mating immediately. In total, we identified 123 putative secreted ACPs, including most important physiological: regulators of proteolysis, transporters and protein export machinery, signal transduction and immunity. Comparing P. xylostella with other four insect ACPs, trypsins were the only ACPs detected in all insect species. This was the first time to identify and analyze ACPs in P. xylostella. Our results have provided an important list of putative secreted ACPs, and have set the stage for further explore functions of these putative proteins in P. xylostella reproduction.

In insects, male accessory gland proteins (ACPs) are important reproductive proteins secreted by male accessory glands (MAGs) of the internal male reproductive system. During mating, ACPs are transferred along with sperms inside female bodies and have a significant impact on the post-mating physiology changes of the females.

Project description:In internally fertilizing organisms, mating involves a series of highly coordinated molecular interactions between the sexes that occur within the female reproductive tract. In species with promiscuous mating systems, traits involved in postcopulatory interactions are expected to evolve rapidly, potentially leading to postmating-prezygotic (PMPZ) reproductive isolation between diverging populations. Here, we use a novel study design to investigate the postmating transcriptional response of Drosophila mojavensis female reproductive tracts following copulation with either conspecific or heterospecific (D. arizonae) males at three time points postmating. Relatively few genes (15 total) were transcriptionally regulated in the female lower reproductive tract in response to conspecific mating. Heterospecifically-mated females exhibited significant perturbations in the expression of the majority of these genes, and also downregulated transcription of a number of others, including several involved in mitochondrial function. These striking regulatory differences indicate failed postcopulatory molecular interactions between the sexes consistent with the strong PMPZ isolation observed for this cross. We also report, for the first time, the transfer of male mRNA transcripts to females during copulation. These included transcripts from male accessory-gland proteins (ACPs), a finding with potentially broad implications for understanding postcopulatory molecular interactions between the sexes.

The treatments were con- and heterospecific mated D. mojavensis females. Three different post-copulation times points were assayed, 15 minutes, 2 hours and 6 hours. For each time point there were two independent replicates. Additionally, two replicates of a virgin D. mojavensis female control were assayed. A total of 14 arrays. All RNA extractions were from the lower reproductive tract of females.
