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

The process whose specific outcome is the progression of sensory organs over time, from its formation to the mature structure.

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 orderly movement of epithelial cells during development of an open tracheal system. An example of this is found in Drosophila melanogaster.

The process whose specific outcome is the progression of the oenocyte over time, from its formation to the mature structure. The oenocytes are large secretory cells found in clusters underlying the epidermis of larval abdominal segments.

The process whose specific outcome is the progression of the heart over time, from its formation to the mature structure. The heart is a hollow, muscular organ, which, by contracting rhythmically, keeps up the circulation of the blood.

The process whose specific outcome is the progression of the somatic muscle over time, from its formation to the mature structure. Somatic muscles are striated muscle structures that connect to the exoskeleton or cuticle.

The series of events required for an organism to receive an auditory stimulus, convert it to a molecular signal, and recognize and characterize the signal. Sonic stimuli are detected in the form of vibrations and are processed to form a sound.

The process whose specific outcome is the progression of the male gonad over time, from its formation to the mature structure.

The process in which anatomical structures of the veins on an imaginal disc-derived wing are generated and organized.

The process whose specific outcome is the progression of a tissue over time, from its formation to the mature structure.

The process by which an organism or tissue maintains a population of stem cells of a single type. This can be achieved by a number of mechanisms: stem cell asymmetric division maintains stem cell numbers; stem cell symmetric division increases them; maintenance of a stem cell niche maintains the conditions for commitment to the stem cell fate for some types of stem cell; stem cells may arise de novo from other cell types.

The process aimed at the progression of a glial cell over time, from initial commitment of the cell to a specific fate, to the fully functional differentiated cell.

The process whose specific outcome is the progression of the neural tube over time, from its formation to the mature structure. The mature structure of the neural tube exists when the tube has been segmented into the forebrain, midbrain, hindbrain and spinal cord regions. In addition neural crest has budded away from the epithelium.

The process, occurring in the embryo, by which the anatomical structures of the limb are generated and organized. A limb is an appendage of an animal used for locomotion or grasping.

The process whose specific outcome is the progression of the male genitalia over time, from its formation to the mature structure.

Any process that restricts, stops or prevents a cell from adopting a terminal cell fate in an open tracheal system. Once the terminal and fusion fates have been correctly induced, inhibitory feedback loops prevent the remaining branch cells from assuming similar fates.

Formation of the tracheal pits, the first tube-like structures to form in the open tracheal system. Once cells are determined to their tracheal cell fate, the tracheal pits arise by invagination of each ectodermal cluster of tracheal placode cells, between 5 and 7 hours after egg laying. An example of this is found in Drosophila melanogaster.

The process in which the anatomical structures of a spiracle are generated and organized. Spiracles are the openings in the insect open tracheal system; externally they connect to the epidermis and internally they connect to the tracheal trunk.

The process in which a cell in the larval wing imaginal disc becomes capable of differentiating autonomously into a notum cell, if left in its normal environment.

Any process that mediates the adoption of a specific fate by a cell.

The process in which a relatively unspecialized cell acquires the specialized features of the R8 photoreceptor.

The process in which a relatively unspecialized cell acquires the specialized features of the R7 photoreceptor.

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 transcription from an RNA polymerase II promoter.

The process whose specific outcome is the progression of the antennal joint over time, from its formation to the mature structure. The antennal joint is the joint between antennal segments.

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

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 compact and highly condensed form of chromatin.

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.

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

A protein complex that is capable of associating with DNA by direct binding, or via other DNA-binding proteins or complexes, and regulating transcription.

A stable assembly of two or more macromolecules, i.e. proteins, nucleic acids, carbohydrates or lipids, in which at least one component is a protein and the constituent parts function together.

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.
