Drosophila spermatogenesis (Fig. 2a) begins at the apical end of the testis 34 where germline stem cells divide asymmetrically, generating mitotically active . Immunostaining of fixed preparations of Drosophila testes can be performed to stage cells undergoing spermatogenesis as well as to assess expression patterns and subcellular localizations of proteins of .

In summary, our study demonstrates that somatic sex maintenance promotes normal spermatogenesis through Chinmo-mediated conserved sex determination and . Drosophila spermatogenesis has become a paradigmatic system for the study of mechanisms that regulate adult stem cell maintenance, proliferation and .Spermatogenesis is an intensively studied developmental process in Drosoph ila melanogaster and Drosophila hydei. Nonetheless, some phases of the develop ment of .
Introduction. Drosophila testes are an ideal model system for the study of many biological processes including the regulation of stem cells, meiosis, and sperm development 13-18.The spermatocytes and . Drosophila melanogaster spermatids undergo dramatic morphological changes as they differentiate from small round cells approximately 12 μm in diameter into highly polarized, 1.8 mm long, motile sperm capable of participating in fertilization. During spermiogenesis, syncytial cysts of 64 haploid spermatids undergo synchronous .
Male gametogenesis requires correlation of both mitotic and meiotic cell cycles with a complex cellular differentiation program. During spermatogenesis in Drosophila, each gonial cell at the tip of the testis undergoes four rounds of synchro-nous mitotic divisions to produce a cyst of sixteen interconnected spermatocytes (reviewed in Fuller, . Drosophila have proven to be a particularly informative model system for the study of spermatogenesis and in this review we discuss how the characterization of the Drosophila melanogaster sperm proteome has advanced our understanding of the evolutionary genomics of sperm form and function. We summarize the molecular .
In this study, we identified 128 testis-specific Drosophila lncRNAs and knocked out 105 of them using an optimized three-component CRISPR/Cas9 system. Among the lncRNA knockouts, 33 (31%) exhibited a partial or complete loss of male fertility, accompanied by visual developmental defects in late spermatogenesis. Figure 1. Spermatogenesis in Drosophila melanogaster.(A) Somatic hub cells (black) physically associate with GSCs (white oval) and CPCs (light gray).Both the GSCs and CPCs undergo self-renewal divisions, producing a (B) pair of daughter cyst cells (dark gray) surrounding a primary spermatogonium (gray).Black squiggles represent .Spermatogenesis is an intensively studied developmental process in Drosophila melanogaster and Drosophila hydei. Nonetheless, some phases of the development of the germ cells are still hardly understood. The main gap of information is with respect to the germ line-soma differentiation and the formation of the gonad.In this study, we found that RpS25 plays a critical role in Drosophila spermatogenesis and its knockdown leads to male sterility. Examination of each stage of spermatogenesis from RpS25-knockdown flies showed that RpS25 was not required for initial germline cell divisions, but was required for spermatid elongation and individualization. In .drosophila spermatogenesis Drosophila spermatogenesis has become a paradigmatic system for the study of mechanisms that regulate adult stem cell maintenance, proliferation and differentiation. The dramatic cellular differentiation process from germline stem cell (GSC) to mature sperm is accompanied by dynamic changes in gene expression, which are .Drosophila researchers have developed an impressive array of sophisticated genetic techniques for analysis of gene function and genetic interactions. This review focuses on how these techniques can be utilised to study spermatogenesis in an organism with a generation time of 9 days and the capacity to introduce multiple mutant alleles into an . For previous excellent reviews of Drosophila spermatogenesis, see refs. Citation 13, Citation 27 – Citation 29. Here, we present a discussion of the stages of spermiogenesis, followed by a description of molecular and cellular mechanisms involved in formation and morphogenesis of sperm-specific organelles and mature, individual sperm.
A Drosophila toolkit for defining gene function in spermatogenesis. Reproduction 153 , R121–R132 (2017). Article CAS PubMed Google Scholarsingle x chromosome We constantly observed mitoballs in larval and adult primary spermatocytes (Fig. 1 B and C and SI Appendix, Fig. S1 A and C).Like in humans and mice, Drosophila spermatogenesis consists of four key steps: 1) differentiation of germline stem cells into spermatogonia cells, 2) mitotic divisions of spermatogonia cells to give rise to primary . Mitochondrial activity in spermatogenesis and in sperm function is essential, where the differentiation of mitochondria during spermatogenesis includes changes in morphology and molecular components [].During Drosophila melanogaster spermatogenesis, intensive mitochondrial dynamics are observable throughout various .
We map the function of Drosophila Pif1A during spermatogenesis, showing that Pif1A is essential for spermatide individualization and involved in the regulation of the lipid metabolism genes. During Drosophila spermatogenesis, germline stem cells (GSCs) located at the hub of the testis divide asymmetrically to produce another GSC and a spermatogonial cell that divides mitotically four times to form a cluster of 16 primary spermatocytes connected by RCs ( Fig. 1 A′,B′). Drosophila have proven to be a particularly informative model system for the study of spermatogenesis and in this review we discuss how the characterization of the Drosophila melanogaster sperm proteome has advanced our understanding of the evolutionary genomics of sperm form and function. Here the authors report the subcellular distributions of approximately 600 Drosophila lncRNAs in male reproductive tissues, indicating potential involvement in spermatogenesis, fertility and . Drosophila spermatogenesis (Fig. 2a) begins at the apical end of the testis 34 where germline stem cells divide asymmetrically, generating mitotically active differentiating daughters called . Immunostaining of fixed preparations of Drosophila testes can be performed to stage cells undergoing spermatogenesis as well as to assess expression patterns and subcellular localizations of proteins of interest.The vinegar fly, Drosophila melanogaster, has been used as a model organism for developmental genetic studies for over one hundred years, and research with this organism produced seminal findings such as the association of genes with chromosomes, the chromosomal basis for sexual identity, the mutagenic properties of X-irradiation and the . In summary, our study demonstrates that somatic sex maintenance promotes normal spermatogenesis through Chinmo-mediated conserved sex determination and the Insulin signaling pathway. Our work offers new insights into the complex mechanisms of somatic stem cell sex maintenance and soma-germline communication at the single-cell .
