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 change in form (cell shape and size) that occurs when relatively unspecialized cells, e.g. embryonic or regenerative cells, acquire specialized structural and/or functional features that characterize the cells, tissues, or organs of the mature organism or some other relatively stable phase of the organism's life history.

Coordinated organization of groups of cells in the plane of an epithelium, such that they all orient to similar coordinates.

Coordinated organization of groups of cells in the plane of an epithelium, such that they all orient to similar coordinates.

Coordinated organization of groups of cells in the plane of an epithelium, such that they all orient to similar coordinates.

Orientation of hairs in the imaginal disc-derived wing along a proximal-distal axis, such that each cell of the wing produces one wing hair which points in a distal direction.

Orientation of hairs in the imaginal disc-derived wing along a proximal-distal axis, such that each cell of the wing produces one wing hair which points in a distal direction.

The attachment of a plasma membrane adhesion molecule in one cell to an identical molecule in an adjacent cell.

The attachment of an adhesion molecule in one cell to a nonidentical adhesion molecule in an adjacent cell.

Coordinated organization of groups of cells in a tissue, such that they all orient to similar coordinates.

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 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.

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

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.

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

The specification and formation of anisotropic intracellular organization or cell growth patterns.

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

The process giving rise to the pattern of cell differentiation in the wing imaginal disc.

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.

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

Any process that modulates the rate, frequency or extent of the establishment of planar polarity, the coordinated organization of groups of cells in a tissue, such that they all orient to similar coordinates.

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.

The component of the plasma membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.

The component of the plasma membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.

The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
