Definition of ommatidial in English: ommatidialadjective Entomology See ommatidium Example sentencesExamples - Histological examination of sections taken through these eyes reveals very minor perturbation of ommatidial organization similar to those seen in Mer / Y eyes alone (data not shown).
- The receptors of the midband which, based on structural evidence, are thought to be specialized to detect and analyze polarized light are in the two most ventral ommatidial rows.
- To determine whether Kek1 functions in a similar manner in the eye, we used ommatidial phenotypes to assay the ability of reduced kek1 function to compensate for reductions in EGFR activity.
- During eye development, HNT function is required for the accumulation of F actin in the apical tip of photoreceptor precursor cells in the ommatidial clusters, as well as in the developing rhabdomere during the pupal period.
- Our results show that rugose gene function is required for correct retinal pattern formation and mutations at the rugose locus affect ommatidial organization, cone cell differentiation, and pigment cell number.
- Each ommatidium of the Drosophila eye is constructed by precisely 19 specified precursor cells, generated in part during a second mitotic wave of cell divisions that overlaps early stages of ommatidial cell specification.
- Within the developing eye disc, these extra photoreceptors appear to occupy the positions of the so-called mystery cells, which normally join the developing unit eye but are then removed during ommatidial assembly.
- In contrast, enhancers of the Tau rough eye phenotype further reduced the eye in size and produced increased ommatidial irregularity and fusion of the overlying lenses.
- The most intensively studied Ras-mediated signaling pathway in Drosophila has been the one that leads to the specification of the R7 photoreceptor in the developing ommatidial clusters of the compound eye.
- However, ommatidial rotation is abnormal in GMR-upd compared to wild type, which is best assessed in the schematics of the WT and GMR-upd adult sections.
- Six glial-like cells are then added to complete the 14-cell ommatidium., An interweaving lattice of support cells emerges in the pupa between ommatidia to precisely organize the ommatidial array.
- However, preliminary analysis has not revealed defects in ommatidial rotation or chirality in sectioned frtz mutant eyes although a low level of these have been seen in in mutants.
- The R8 precursor acts as a founder cell around which all other ommatidial cell types are progressively recruited through a series of inductions mediated by Sevenless and the epidermal growth factor receptor.
- The distal staining ensheathed the pseudocone and showed tapering extensions toward the basement membrane at ommatidial periodicity, indicative of expression in pigment cells.
- The eye is composed of a repeating array of 800 ommatidial clusters, each of which comprises 20 cells including 8 neuronal photoreceptor cells designated R1 - R8.
- Section of a bnd clone viewed under light microscopy shows no recognizable photoreceptors or ommatidial organization in the mutant tissue.
- The hyperactivation of the Sevenless RTK-signaling pathway in the Drosophila eye causes the ommatidial precursors to differentiate as neurons and results in a rough eye phenotype.
- Using the R3 / R4 marker anti-SALM, ommatidial clusters that contain three SALM-positive nuclei were observed.
- The hormones triggering chromatophoral pigment dispersion and ommatidial light adaptation belong to one set, and these are distinct from those responsible for chromatophoral pigment concentration and ommatidial dark adaptation.
- However, in some cases both cells adopted the R7 fate, resulting in an ommatidial cluster containing three R7 neurons (cross hatched arrow, Figure 9D).
