The process whose specific outcome is the progression of the peripheral nervous system over time, from its formation to the mature structure. The peripheral nervous system is one of the two major divisions of the nervous system. Nerves in the PNS connect the central nervous system (CNS) with sensory organs, other organs, muscles, blood vessels and glands.

The projection of branches of an open tracheal system towards their target tissues. An example of this is found in Drosophila melanogaster.

Any process that modulates the surface configuration of a cell.

Any process that modulates the surface configuration of an embryonic cell.

The process that occurs during oogenesis involving the ovarian follicle cells, somatic cells which surround the germ cells of an ovary. An example of this is found in Drosophila melanogaster.

Growth of epithelial tubes that originate from pits in an open tracheal system and grow towards each other to meet and form a continuous open tube called the dorsal trunk. The dorsal trunk extends from the anterior spiracle to the posterior spiracle of the larva and forms the main airway of the insect tracheal system.

Fusing of specific tracheal branches in an open tracheal system to branches from neighboring hemisegments to form a continuous tracheal network. Branch fusion is mediated by individual cells at the tip of each branch, which contact a similar cell and undergo a coordinated series of morphogenetic events that create a bicellular fusion joint.

Ensuring that an epithelial tube in an open tracheal system is of the correct length and diameter. Tracheal tubes undergo highly regulated tube-size increases during development, expanding up to 40 times their initial size by the end of larval life. Tube size appears to be controlled by regulation of apical membrane expansion and secretion, rather than by changes in cell number, size or shape.

Synthesis and deposition of a chitin-based noncellular, hardened, or membranous secretion from an epithelial sheet. An example of this process is found in Drosophila melanogaster.

The process in which a relatively unspecialized cell acquires the specialized features of a compound eye cone cell, a cone-shaped cell, that focuses light in a compound eye.

Any process that mediates the specification of a cell into a compound eye cone cell.

Any process that mediates the specification of a cell into a compound eye cone cell.

Any process that increases the frequency, rate or extent of DNA binding. DNA binding is any process in which a gene product interacts selectively with DNA (deoxyribonucleic acid).

The process whose specific outcome is the progression of the R7 photoreceptor over time, from its formation to the mature structure. The R7 photoreceptor is the last photoreceptor to develop in the ommatidium.

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

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.

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

The process whose specific outcome is the progression of the R1 and R6 pair of photoreceptors in the eye over time, from their formation to the mature structures. R1 and R6 are paired photoreceptors that contribute to the outer rhabdomeres. An example of this process is found in Drosophila melanogaster.

The process in which a cell becomes capable of differentiating autonomously into a myoblast in an environment that is neutral with respect to the developmental pathway. Upon specification, the cell fate can be reversed. A myoblast is a mononucleate cell type that, by fusion with other myoblasts, gives rise to the myotubes that eventually develop into skeletal muscle fibers.

The process in which the anatomical structures of the compound eye corneal lens are generated and organized.

The morphogenetic process in which an epithelium narrows along one axis and lengthens in a perpendicular axis.

The process in which the anatomical structures of branches in the open tracheal system are generated and organized.

Any process that activates or increases the frequency, rate or extent of border follicle cell migration.

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 type of chromosome in a polyploid cell, formed when multiple copies of homologous chromosomes are aligned side by side to give a giant chromosome in which distinct chromosome bands are readily visible.

A protein complex that possesses activity that prevents or downregulates transcription.
