The process whose specific outcome is the progression of a pancreatic A cell over time, from its formation to the mature structure. A pancreatic A cell is a cell in the pancreas that secretes glucagon.

Any process that modulates the frequency, rate or extent of rhodopsin gene expression. This includes transcriptional, translational, or posttranslational regulation.

The process whose specific outcome is the progression of the telencephalon over time, from its formation to the mature structure. The telencephalon is the paired anteriolateral division of the prosencephalon plus the lamina terminalis from which the olfactory lobes, cerebral cortex, and subcortical nuclei are derived.

The process whose specific outcome is the progression of the subthalamus over time, from its formation to the mature structure. The subthalamus is the anterior part of the diencephalon that lies between the thalamus, hypothalamus, and tegmentum of the mesencephalon, including subthalamic nucleus, zona incerta, the fields of Forel, and the nucleus of ansa lenticularis.

The process in which the thalamus changes over time, from its initial formation to its mature state.

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 assembly and arrangement of a rhabdomere within a cell. The rhabdomere is the organelle on the apical surface of a photoreceptor cell that contains the visual pigments.

Development of photoreceptors, sensory cells that react to the presence of light, found in the ocellus.

Any process that activates or increases the frequency, rate or extent of cellular DNA-templated transcription.

The process whose specific outcome is the progression of a neuron over time, from initial commitment of the cell to a specific fate, to the fully functional differentiated cell.

Any process that stops, prevents, or reduces the frequency, rate or extent of transcription mediated by RNA polymerase II.

The characteristic movement of an immature neuron from germinal zones to specific positions where they will reside as they mature.

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 the brain over time, from its formation to the mature structure. Brain development begins with patterning events in the neural tube and ends with the mature structure that is the center of thought and emotion. The brain is responsible for the coordination and control of bodily activities and the interpretation of information from the senses (sight, hearing, smell, etc.).

The process in which the anatomical structures of a leg derived from an imaginal disc are generated and organized. A leg is a limb on which an animal walks and stands. An example of this is found in Drosophila melanogaster.

Any process that increases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA or circRNA (for protein-coding genes) and the translation of that mRNA or circRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form.

The progression of the globus pallidus over time from its initial formation until its mature state. The globus pallidus is one of the basal ganglia involved with control of voluntary movement in the brain.

The progression of the olfactory bulb over time from its initial formation until its mature state. The olfactory bulb coordinates neuronal signaling involved in the perception of smell. It receives input from the sensory neurons and outputs to the olfactory cortex.

The migration of cells in the cerebral cortex in which cells move orthogonally to the direction of radial migration and do not use radial glial cell processes as substrates for migration.

The directed movement of individual interneuron precursors during the embryonic development of the olfactory bulb.

The creation of greater cell numbers in the forebrain due to cell division of progenitor cells.

The migration of GABAergic interneuron precursors from the subpallium to the cerebral cortex.

The process whose specific outcome is the progression of a chaeta over time, from its formation to the mature structure. A chaeta is a sensory multicellular cuticular outgrowth of a specifically differentiated cell.

The process whose specific outcome is the progression of the forebrain over time, from its formation to the mature structure. The forebrain is the anterior of the three primary divisions of the developing chordate brain or the corresponding part of the adult brain (in vertebrates, includes especially the cerebral hemispheres, the thalamus, and the hypothalamus and especially in higher vertebrates is the main control center for sensory and associative information processing, visceral functions, and voluntary motor functions).

The increase in length of the aristal core. The arista is the terminal segment of the antenna and consists of a central core and a series of lateral extensions.

Progression of the leg imaginal disc over time, from its initial formation through to its metamorphosis to form adult structures including the leg, coxa and ventral thoracic pleura.

Any process that modulates the frequency, rate or extent of cell proliferation.

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

The whole of the physical, chemical, and biochemical processes carried out by living organisms to break down ingested lipids into components that may be easily absorbed and directed into metabolism.

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

Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter.

Any process that activates or increases the frequency, rate or extent of growth of an organ of an organism.

The process whose specific outcome is the progression of a neuron over time, from initial commitment of the cell to a specific fate, to the fully functional differentiated cell.

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

The process in which the developmental fate of a cell becomes restricted such that it will develop into an epithelial cell.

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.
