Any process that initiates the activity of the inactive enzyme MAP kinase kinase kinase (MAPKKK).

Construction of a stage-1 egg chamber in the anterior part of the germarium, from the progeny of germ-line and somatic stem cells. An example of this is found in Drosophila melanogaster.

Transfer of constituents synthesized in the ovarian nurse cells to the oocyte, through the ring canals, as the egg chamber is growing. An example of this is found in Drosophila melanogaster.

Assembly of the intercellular bridges that connect the germ-line cells of a female cyst.

The separation of a multi-nucleate cell or syncytium into individual cells. An example of this is found in Drosophila melanogaster embryo development.

The chemotaxis process that directs the migration of an axon growth cone to a specific target site in response to a combination of attractive and repulsive cues.

The process whose specific outcome is the progression of an open tracheal system over time, from its formation to the mature structure. An open tracheal system is a respiratory system, a branched network of epithelial tubes that supplies oxygen to target tissues via spiracles. An example of this is found in Drosophila melanogaster.

The process in which the anatomical structures of the salivary gland are generated and organized.

The memory process that deals with the storage, retrieval and modification of information a long time (typically weeks, months or years) after receiving that information. This type of memory is typically dependent on gene transcription regulated by second messenger activation.

Any process that modulates the frequency, rate or extent of the assembly or disassembly of actin filaments by the addition or removal of actin monomers from a filament.

Recruitment and organization of actin filaments in female germline ring canals.

Maintenance of the structural integrity of the ring canals connecting the female germline cyst.

The process whose specific outcome is the progression of the mushroom body over time, from its formation to the mature structure. The mushroom body is composed of the prominent neuropil structures of the insect central brain, thought to be crucial for olfactory associated learning. These consist mainly of a bulbous calyx and tightly packaged arrays of thin parallel fibers of the Kenyon cells.

The phosphorylation of peptidyl-tyrosine to form peptidyl-O4'-phospho-L-tyrosine.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of cytoskeletal structures comprising actin filaments and their associated proteins.

Assembly of actin filament bundles in which the filaments are tightly packed (approximately 10-20 nm apart) and oriented with the same polarity.

Formation of a single follicular epithelium around the germ-line derived cells of a cyst formed in the germarium. An example of this process is found in Drosophila melanogaster.

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

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the fusome of ovarian cells, an organelle derived from the spectrosome. It anchors the mitotic spindle pole to provide orientation during cystoblast cell divisions.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of an adherens junction. An adherens junction is a cell junction at which the cytoplasmic face of the plasma membrane is attached to actin filaments.

The aggregation, arrangement and bonding together of a set of components to form a filtration diaphragm, a specialized cell-cell junction found between the cells of the excretory system, which provides a barrier for filtration of blood or hemolymph.

Any process that activates or increases the frequency, rate or extent of epidermal growth factor receptor signaling pathway activity.

Any process that activates or increases the frequency, rate or extent of fibroblast growth factor receptor signaling pathway activity.

Any process that activates or increases the frequency, rate or extent of the sevenless signaling pathway.

Any process that stops, prevents, or reduces the frequency, rate or extent of synaptic growth at neuromuscular junction.

A process that modulates synaptic plasticity, the ability of synapses to change as circumstances require. They may alter function, such as increasing or decreasing their sensitivity, or they may increase or decrease in actual numbers.

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 attachment of an epithelial cell to another epithelial cell via adhesion molecules.

Any process that activates or increases the frequency, rate or extent of the torso signaling pathway.

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

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

Germline specific intercellular bridge. During cyst formation in insects, ring canals interconnect the cells of the cyst, facilitating the passage of cytoplasmic components between cells.
