The dynamics of Drosophila melanogaster spermatogenesis in in vitro cultures.
A photographic description of meiosis and spermatogenesis in single sperm cysts of Drosophila melanogaster cultured in vitro is presented. In addition to the utility of this description for the study of spermatogenesis in whole live testes, the culture procedure provides a means for studying the dynamic development of individual sperm cysts from flies carrying male-sterile mutations, as illustr...
متن کاملAnent the Genomics of Spermatogenesis in Drosophila melanogaster
An appreciable fraction of the Drosophila melanogaster genome is dedicated to male fertility. One approach to characterizing this subset of the genome is through the study of male-sterile mutations. We studied the relation between vital and male-fertility genes in three large autosomal regions that were saturated for lethal and male-sterile mutations. The majority of male-sterile mutations affe...
متن کاملDirect evidence for postmeiotic transcription during Drosophila melanogaster spermatogenesis.
Extensive gene expression during meiosis is a hallmark of spermatogenesis. Although it was generally accepted that RNA transcription ceases during meiosis, recent observations suggest that some transcription occurs in postmeiosis. To further resolve this issue, we provide direct evidence for the de novo transcription of RNA during the postmeiotic phases. These results strengthen the newly emerg...
متن کاملInvestigating auditory transduction functions of myosin VII in Drosophila melanogaster
In a quest to better understand hereditary human deafness we focus on the motor protein myosin VIIA (MyoVIIA), mutations in which underlie dysfunctions in auditory, vestibular and visual processes. Proposed MyoVIIA inner ear functions include tethering transduction channels, trafficking proteins and anchoring hair cell stereocilia by associating with adherens junctions. Fueled by the interest t...
متن کاملToxicological Evaluation of a New Lepidopteran Insecticide, Flubendiamide, in Non-Target Drosophila melanogaster Meigen (Diptera: Drosophilidae)
Background: Flubendiamide, comparatively a new pesticide designed to eradicate lepidopteran insect pests is known to have low risk to birds, mammals, fish, algae, honey bees, non-target arthropods, earthworms, soil macro- and micro-organisms, non-target plants as well as sewage treatment organisms; however, the risk assessment for aquatic invertebrates from metabolite could not be finalized wit...
