The male accessory glands in Triatoma are tubular and produce substances with some functions related to production of the spermatophore. In the current study, the cytochemistry of male accessory glands was evaluated in starved Triatoma brasiliensis and adult Triatoma melanica. The storage of carbohydrates and ...

Female reproductive accessory glands of the medfly Ceratitis capitata produce a secretion with antibacterial activity mainly ascribed to ceratotoxin peptides. To study whether the secretion from the accessory glands of the female protects the eggs and early larva from microbes, we examined whether ceratotoxins and ...

Such reproductive proteins often evolve proteomic method that uses whole-organism isotopic labeling to detect transferred Sfps in mated female D on three areas: (a) the effects of the full set of Sfps (and especially of accessory gland proteins
The relative importance of testosterone and prolactin in regulating growth and protein synthesis in rat accessory sex glands has been investigated. Protein synthesis was measured by incubating tissue minces in vitro with [35S]methionine and analysing labelled proteins on polyacrylamide gels ...
To investigate the potential importance of gene duplication in D. melanogaster accessory gland protein (Acp) gene evolution we carried out a computational analysis comparing annotated D. melanogaster Acp genes to the entire D. melanogaster genome. We found that two known Acp genes are actually members of small multigene families. ...
Genes expressed in the male reproductive system exhibit rapid evolutionary change and encode products that underlie striking, fitness-related phenotypes. Despite this, they have been characterised in detail in relatively few species. We report here an initial characterisation of the genes expressed in the male reproductive accessory glands of the ...

Metacestodes of Hymenolepis diminuta affect several aspects of female reproductive physiology in Tenebrio molitor and such effects are mediated via the endocrine system. The effects on male reproduction are less well known and were studied with respect to the Bean-Shaped Accessory Glands (BAGs). The size and wet and dry weight of BAGs from infected and ...
This study investigated progesterone receptor (PR) cDNA expression in the testes, prostate and bulbourethral glands of prepubertal calves treated experimentally with high and low doses of 17beta-oestradiol and with testosterone. Tissue samples were examined histologically and immunohistochemically for PR. Western blot analysis and quantitative PCR against PR was performed on ...
Male insects change behaviors of female partners by co-transferring accessory gland proteins (Acps) like sex peptide (SP), with their sperm. The Drosophila sex peptide receptor (SPR) is a G protein-coupled receptor expressed in the female¿s nervous system and genital tract. While most Acps show a fa...

The volumetric changes of the corpora allata (CA) during the first 15 days of imaginal life of Blatta orientalis L. (Dictyoptera, Blattidae) are studied in connection with the growth of the accessory reproductive glands (GSAM). Both, the CA and the GSAM, grow in parallel during the first 3-4 days of imaginal life, which suggests a possible functional link ...
The constituents of seminal fluid are a complex mixture of proteins and other molecules, most of whose functions have yet to be determined and many of which are rapidly evolving. As a step in elucidating the roles of these proteins and exposing potential functional similarities hidden by their rapid evolution, we performed comparative structural modeling ...

BackgroundHeliconius butterflies possess a remarkable diversity of phenotypes, physiologies, and behaviors that has long distinguished this genus as a focal taxon in ecological and evolutionary research. Recently Heliconius has also emerged as a model system for using genomic methods to investigate the causes and consequences of biological diversity. One notable aspect of Heliconius diversity is a ...
The accessory glands of seven species of male chiropterans are described. The unpaired prostate and paired Cowper's glands occur in all the species. The seminal vesicles are present only in Cynopterus and Taphozous. The ampullary glands occur in all the species except Cynopterus sphinx. The presence of solid ...
BackgroundInternal reproductive organ size is an important determinant of male reproductive success. While the response of testis length to variation in the intensity of sperm competition is well documented across many taxa, few studies address the importance of testis size in determining other components of male reproductive success (such as mating frequency) or the significance of size variation ...
