The morphogenetic furrow is a dorsoventral indentation which sweeps anteriorly across the eye disc. Ommatidia begin to form along the furrow, resulting in a graded series of ommatidial development across the anterior/posterior axis of the disc.

Any process that activates or increases the frequency, rate or extent of mitotic division septum formation. Division septum formation is the assembly and arrangement of a septum that spans the plasma membrane interface between progeny cells following cytokinesis.

Any process that stops, prevents or reduces the frequency, rate or extent of mitotic cytokinetic process.

Any process that stops or reduces the activity of a sodium:hydrogen antiporter, which catalyzes the reaction: Na+(out) + H+(in) = Na+(in) + H+(out).

Any process that modulates the activity of a sodium:hydrogen antiporter, which catalyzes the reaction: Na+(out) + H+(in) = Na+(in) + H+(out).

Any process in which a lysosome is transported to, and/or maintained in, a specific location.

Any process that activates or increases the activity of a sodium:hydrogen antiporter, which catalyzes the reaction: Na+(out) + H+(in) = Na+(in) + H+(out).

The component of an lysosome membrane consisting of gene products and protein complexes that are loosely bound to one of its surfaces, but not integrated into the hydrophobic region.

The cell cycle process where kinetochore microtubule attachment defects are corrected.

The process in which the R8 photoreceptor commits to its cell fate. The R8 receptor contributes the central part of the rhabdomere in the basal parts of the ommatidium.

The process in which the R2/R5 photoreceptors commit to their cell fate. R2 and R5 are paired photoreceptors which contribute the outer rhabdomeres.

The process in which the R1/R6 photoreceptors commit to their cell fate. R1 and R6 are paired photoreceptors which contribute the outer rhabdomeres.

The assembly and arrangement of a septum that spans the plasma membrane interface between progeny cells following mitotic cytokinesis. The progeny cells that form a division septum are not able to exchange intracellular material.

The process in which the R7 photoreceptor commits to its cell fate. The R7 receptor contributes the central part of the rhabdomere in the apical parts of the ommatidium.

The process in which the R3/R4 photoreceptors commit to their cell fate. R3 and R4 are paired photoreceptors which contribute the outer rhabdomeres.

OBSOLETE. Any heterochromatin maintenance that is involved in chromatin silencing at or near a centromere.
