A cell cycle process by which the cell nucleus divides as part of a meiotic cell cycle in the male germline.

The process of formation of spermatozoa, including spermatocytogenesis and spermiogenesis.

The union of gametes of opposite sexes during the process of sexual reproduction to form a zygote. It involves the fusion of the gametic nuclei (karyogamy) and cytoplasm (plasmogamy).

The chemical reactions and pathways involving piRNAs, Piwi-associated RNAs, a class of 24- to 30-nucleotide RNA derived from repeat or complex DNA sequence elements and processed by a Dicer-independent mechanism.

The covalent transfer of a methyl group to C-5 of cytosine that contributes to the establishment of DNA methylation patterns in the gamete.

Any process that stops, prevents, or reduces the frequency, rate or extent of DNA transposition.

A developmental process, independent of morphogenetic (shape) change, that is required for an oocyte to attain its fully functional state. Oocyte maturation commences after reinitiation of meiosis commonly starting with germinal vesicle breakdown, and continues up to the second meiotic arrest prior to fertilization.

Repression of transcription by altering the structure of chromatin, e.g. by conversion of large regions of DNA into an inaccessible state often called heterochromatin.

A process in which RNA is transported to, or maintained in, a specific location.

The cell cycle process in which chromatin structure is compacted prior to and during mitosis in eukaryotic cells.

A cell cycle process by which the cell nucleus divides as part of a meiotic cell cycle in the male germline.

The process of formation of spermatozoa, including spermatocytogenesis and spermiogenesis.

The cell fate determination process in which a germarium-derived cell becomes capable of differentiating autonomously into an oocyte cell regardless of its environment; upon determination, the cell fate cannot be reversed. An example of this is found in Drosophila melanogaster.

Establishment of the specialized cytoplasm found at the poles of the egg. An example of this is found in Drosophila melanogaster.

Any process that modulates the frequency, rate or extent of the process in which oskar mRNA is transported to, or maintained in, the oocyte pole plasm.

Any process in which mRNA is transported to, or maintained in, a specific location within the cell.

Any process in which mRNA is transported to, or maintained in, a specific location within the cell.

The union of gametes of opposite sexes during the process of sexual reproduction to form a zygote. It involves the fusion of the gametic nuclei (karyogamy) and cytoplasm (plasmogamy).

Any process resulting in the establishment of polarity along the anterior/posterior axis.

Any process resulting in the establishment of polarity along the dorsal/ventral axis.

Any process that decreases the frequency, rate or extent of transposition. Transposition results in the movement of discrete segments of DNA between nonhomologous sites.

The process in which double-stranded RNAs silence cognate genes. Involves posttranscriptional gene inactivation ('silencing') both of transgenes or dsRNA introduced into a germline, and of the host gene(s) homologous to the transgenes or dsRNA. This silencing is triggered by the introduction of transgenes or double-stranded RNA (dsRNA), and can occur through a specific decrease in the level of mRNA, or by negative regulation of translation, of both host genes and transgenes.

The process in which small interfering RNAs target cognate mRNA molecules for degradation.

The chromosome organization process in which meiotic chromosomes in the oocyte nucleus cluster together to form a compact spherical structure called the karyosome.

Directed movement of the oocyte, following its specification, from its original central position in the cyst to a posterior position relative to the nurse cells of the egg chamber, and its maintenance in this posterior location. This is the first sign of anterior-posterior asymmetry in the developing egg chamber.

The chemical reactions and pathways involving piRNAs, Piwi-associated RNAs, a class of 24- to 30-nucleotide RNA derived from repeat or complex DNA sequence elements and processed by a Dicer-independent mechanism.

Any process in which oskar mRNA is transported to, or maintained in, the oocyte pole plasm.

Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription.

Establishment of the dorsal filaments, elaborate specializations of the chorion that protrude from the anterior end of the egg and facilitate embryonic respiration.

The complete process of formation and maturation of an ovum or female gamete from a primordial female germ cell. Examples of this process are found in Mus musculus and Drosophila melanogaster.

The complete process of formation and maturation of an ovum or female gamete from a primordial female germ cell. Examples of this process are found in Mus musculus and Drosophila melanogaster.

The complete process of formation and maturation of an ovum or female gamete from a primordial female germ cell. Examples of this process are found in Mus musculus and Drosophila melanogaster.

Any process that increases the frequency, rate or extent of poly(A) tail shortening of a nuclear-transcribed mRNA. Poly(A) tail shortening is the decrease in length of the poly(A) tail of an mRNA from full length to an oligo(A) length.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

A P granule that contains the PIWIL4-TDRD9 module, a set of proteins that act in the secondary piRNA pathway.

That part of the nuclear content other than the chromosomes or the nucleolus.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

A small cytoplasmic, non-membranous RNA/protein complex aggregates in the primordial germ cells of many higher eukaryotes.
