Effect of precocene on development of ovarian follicles in flesh fly, Sarcophaga ruficornis F.
Administration of precocene II (6,7-dimethoxy-2, 2-dimethyl chromene) to freshly emerged virgin female flies of S. ruficornis adversely affected the development and differentiation of ovarian follicles leading to a number of morphological abnormalities. Precocene treatment resulted into suppression of development of egg chamber, differentiation of follicular epithelium, degeneration of nurse ce...
متن کاملDiapause-specific gene expression in pupae of the flesh fly Sarcophaga crassipalpis.
Several cDNAs isolated from brains of diapausing pupae of the flesh fly, Sarcophaga crassipalpis, show expression patterns unique to diapause. To isolate such cDNAs a diapause pupal brain cDNA library was screened by using an elimination hybridization technique, and cDNAs that did not hybridize with cDNA probes constructed from the RNA of nondiapausing pupae were selected for further screening....
متن کاملInterchromatin granule clusters in vitellogenic oocytes of the flesh fly, Sarcophaga sp.
Insect oocyte nuclei contain different extrachromosomal nuclear bodies including Cajal bodies and interchromatin granule clusters (IGCs). In the present study, we describe IGC equivalents in the vitellogenic oocytes of the flesh fly, Sarcophaga sp. These structures were found to consist of 20-40-nm granules and also include the fibrillar areas of high and low electron density. Immunogold labeli...
متن کاملProteomic approach to understanding the maternal effect in the flesh fly, Sarcophaga bullata (Diptera: Sarcophagidae)
Progeny of the flesh fly Sarcophaga bullata exposed to short day length show a maternal effect that prevents the expression of pupal diapause. Although ecological aspects of this effect are well studied, not enough is known about the molecular mechanisms underlying this maternal effect. In this study, two-dimensional electrophoresis was performed to detect differences of the abundance of certai...
متن کاملMendelian inheritance of pupal diapause in the flesh fly, Sarcophaga bullata.
Pupal diapause (dormancy) in the flesh fly, Sarcophaga bullata, is induced by short-day photoperiods and low temperature. In this study, the inheritance mode of diapause was investigated by crossing a nondiapausing (nd) strain of S. bullata with 2 diapausing strains having different diapause capacities. The results consistently indicated that diapause incidence is inherited in a simple Mendelia...
