The increase in mass of imaginal discs by cell proliferation prior to metamorphosis. Imaginal discs are epithelial infoldings in the larvae of holometabolous insects that develop into adult structures (legs, antennae, wings, etc.) during metamorphosis from larval to adult form.

The regionalization process that results in defined areas of the imaginal disc that will undergo specific cell differentaiton. Imaginal discs are epithelial infoldings in the larvae of holometabolous insects that develop into adult appendages (legs, antennae, wings, etc.) during metamorphosis from larval to adult form.

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.

The multiplication or reproduction of cells, resulting in the expansion of a cell population.

Any process that stops, prevents or reduces the rate or extent of cell proliferation.

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

Any process that decreases 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 (for protein-coding genes) and the translation of that mRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form.

The process in which photoreceptors are arranged in ommatidia in the dorsal and ventral fields to be mirror images. The polarity is established in the imaginal discs concurrently with cell fate specification.

Any cellular process that results in the specification, formation or maintenance of a polarized larval imaginal disc epithelium.

The attachment of one cell to another cell via adhesion molecules, where both cells are part of the same organism.

The attachment of one cell to another cell via adhesion molecules that require the presence of calcium for the interaction.

The attachment of one cell to another cell via adhesion molecules that require the presence of calcium for the interaction.

The attachment of one cell to another cell via adhesion molecules that require the presence of calcium for the interaction.

The formation of a covalent cross-link between or within protein chains.

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

Any process that modulates the frequency, rate or extent of any process in which a protein is transported to, or maintained in, a specific location.

Ensuring that a tube in an open tracheal system is of the correct length.

The process whose specific outcome is the progression of the pupa over time, from its formation to the mature structure. The pupa is a dormant life stage interposed between the larval and the adult stages in insects that undergo a complete metamorphosis.

Progression of the wing disc over time, from its initial formation through to its metamorphosis to form adult structures including the wing hinge, wing blade and pleura.

The series of molecular signals mediated by the serine/threonine kinase Hippo or one of its orthologs. In Drosophila, Hippo in complex with the scaffold protein Salvador (Sav), phosphorylates and activates Warts (Wts), which in turn phosphorylates and inactivates the Yorkie (Yki) transcriptional activator. The core fly components hippo, sav, wts and mats are conserved in mammals as STK4/3 (MST1/2), SAV1/WW45, LATS1/2 and MOB1.

Any process that modulates the frequency, rate or extent of the growth of all or part of an organism so that it occurs at its proper speed, either globally or in a specific part of the organism's development.

Any process that modulates the frequency, rate or extent of the growth of all or part of an organism so that it occurs at its proper speed, either globally or in a specific part of the organism's development.

The specification of polarized ommatidia. Ommatidia occur in two chiral forms. The trapezoidal arrangement of photoreceptors in the dorsal part of the eye is the mirror image of that in the ventral part.

The attachment of one cell to another cell via a cadherin, transmembrane proteins having repeating extracellular calcium ion binding domains.

The specification and formation of the apicobasal polarity of an epithelial cell.

The formation and development of the equator that forms the boundary between the photoreceptors in the dorsal sector of the eye and those in the ventral sector, dividing the eye into dorsal and ventral halves.

Any process that modulates the frequency, rate or extent of the growth of the imaginal disc.

Any process that stops, prevents, or reduces the frequency, rate or extent of imaginal disc growth.

Any process that stops, prevents, or reduces the frequency, rate or extent of imaginal disc growth.

Any process that stops, prevents or reduces the rate or extent of growth, the increase in size or mass of all or part of an organism.

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

Orientation of body hairs, projections from the surface of an organism, such that the hairs all point in a uniform direction along the surface.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of cytoskeletal structures comprising microtubules and their associated proteins and contributes to the establishment of planar polarity.
