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

The process whose specific outcome is the progression of the epidermis over time, from its formation to the mature structure. The epidermis is the outer epithelial layer of an animal, it may be a single layer that produces an extracellular material (e.g. the cuticle of arthropods) or a complex stratified squamous epithelium, as in the case of many vertebrate species.

A transition where an epithelial cell loses apical/basolateral polarity, severs intercellular adhesive junctions, degrades basement membrane components and becomes a migratory mesenchymal cell.

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 whose specific outcome is the progression of the antenna over time, from its formation to the mature structure. The antenna are the sensory structures on the head that are capable of detecting various environmental stimuli.

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 establishment, maintenance and elaboration of the proximal/distal axis of the leg imaginal disc, a precursor to the adult leg.

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

The timing of the emergence of the adult fly from its pupal case, which usually occurs at dawn.

Any process that modulates 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 rhythm of the locomotor activity of an organism during its 24 hour activity cycle.

Any process preventing the degeneration of the photoreceptor, a specialized cell type that is sensitive to light.

Any process that activates or increases 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.

The process of expanding or inflating the folded imaginal disc-derived pupal wing, and the adhering of the dorsal and ventral surfaces, to form the mature adult wing.

The process of negative regulation of cell adhesion that results in a cell or sheet of cells splitting off from an existing epithelial sheet.

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

Organized structure of distinctive morphology and function, bounded by a single or double lipid bilayer membrane and occurring within the cell. Includes the nucleus, mitochondria, plastids, vacuoles, and vesicles. Excludes the plasma membrane.

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.
