A complex and coordinated series of cellular movements that occurs at the end of cleavage during embryonic development of most animals. The details of gastrulation vary from species to species, but usually result in the formation of the three primary germ layers, ectoderm, mesoderm and endoderm.

Formation of terminal branches in the open tracheal system. These are long cytoplasmic extensions that form fine tubules that transport oxygen directly to the tissues. An example of the process is found in Drosophila melanogaster.

The process in which the R7 photoreceptor commits to its cell fate. The R7 receptor contributes the central part of the rhabdomere in the apical parts of the ommatidium.

The process in which the anatomical structures derived from the wing disc are generated and organized. This includes the transformation of a wing imaginal disc from a monolayered epithelium in the larvae of holometabolous insects into recognizable adult structures including the wing hinge, wing blade and pleura.

The regionalization process in which the area of a imaginal disc-derived wing that will form a wing vein is specified.

The process in which the anatomical structures of the imaginal disc-derived wing are generated and organized. The wing is an appendage modified for flying.

A biological process in which an animal physically develops after birth or hatching, involving a conspicuous and relatively abrupt change in the animal's form or structure. Examples include the change from tadpole to frog, and the change from larva to adult. An example of this is found in Drosophila melanogaster.

Any biological process in an organism that recurs with a regularity of approximately 24 hours.

Polarization of the ovarian follicle cells along the dorsal/ventral axis. An example of this process is found in Drosophila melanogaster.

Any process that activates or increases the rate or extent of cell proliferation.

A series of molecular signals initiated by the binding of an extracellular ligand to torso (a receptor tyrosine kinase) on the surface of a target cell, and ending with regulation of a downstream cellular process, e.g. transcription.

The series of molecular signals generated as a consequence of a fibroblast growth factor receptor binding to one of its physiological ligands.

The series of molecular signals generated as a consequence of a fibroblast growth factor receptor binding to one of its physiological ligands.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of deprivation of nourishment.

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

Any process involved in the maintenance of an internal equilibrium of hydrogen ions (protons) within a cell or between a cell and its external environment.

The process in which a relatively unspecialized hemocyte precursor cell acquires the specialized features of a lamellocyte. Lamellocytes are a hemocyte lineage that exists only in larvae, but are seldom observed in healthy animals. Lamellocytes differentiate massively in the lymph glands after parasitization and are large flat cells devoted to encapsulation of invaders too large to be phagocytosed by plasmatocytes.

The regionalization process that subdivides the wing imaginal disc into the wing and notum (body wall) subfields, thus determining whether cells ultimately differentiate wing or notum-specific structures.

Any process that modulates the frequency, rate or extent of growth of the body of an organism so that it reaches its usual body size.

The process whose specific outcome is the progression of a light-responsive receptor in the compound eye over time, from its formation to the mature structure.

The process in which a relatively unspecialized cell acquires the characteristics of a mature hemocyte. Hemocytes are blood cells associated with a hemocoel (the cavity containing most of the major organs of the arthropod body) which are involved in defense and clotting of hemolymph, but not involved in transport of oxygen.

Development of a photoreceptor, a cell that responds to incident electromagnetic radiation, particularly visible light.

Any process that activates or increases the frequency, rate or extent of photoreceptor cell differentiation. An example of this process is found in Drosophila melanogaster.

The phosphorylation by a protein of one or more of its own amino acid residues (cis-autophosphorylation), or residues on an identical protein (trans-autophosphorylation).

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

An intracellular protein kinase cascade containing at least ERK1 or ERK2 (MAPKs), a MEK (a MAPKK) and a MAP3K. The cascade may involve 4 different kinases, as it can also contain an additional tier: the upstream MAP4K. The kinases in each tier phosphorylate and activate the kinase in the downstream tier to transmit a signal within a cell.

Any process that activates or increases the frequency, rate or extent of signal transduction mediated by the ERK1 and ERK2 cascade.

Any process that stops, prevents or reduces the frequency, rate or extent of apoptotic signaling pathway.
