Available in PDF, EPUB and Kindle. Book excerpt: 1 Kevin Moses It is now 25 years since the study of the development of the compound eye in Drosophila really began with a classic paper (Ready et al. 1976). In 1864, August Weismann published a monograph on the development of Diptera and included some beautiful drawings of the developing imaginal discs (Weismann 1864). One of these is the first description of the third instar eye disc in which Weismann drew a vertical line separating a posterior domain that included a regular pattern of clustered cells from an anterior domain without such a pattern. Weismann suggested that these clusters were the precursors of the adult ommatidia and that the line marks the anterior edge of the eye. In his first suggestion he was absolutely correct - in his second he was wrong. The vertical line shown was not the anterior edge of the eye, but the anterior edge of a moving wave of patterning and cell type specification that 112 years later (1976) Ready, Hansen and Benzer would name the "morphogenetic furrow". While it is too late to hear from August Weismann, it is a particular pleasure to be able to include a chapter in this Volume from the first author of that 1976 paper: Don Ready! These past 25 years have seen an astonishing explosion in the study of the fly eye (see Fig.

This book was released on 2007 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: (Cont.) First, we characterized the eye phenotypes arising from overexpression of nito. Overexpression of nito perturbs eye development and in contrast to spen, which has been shown to act as a positive effector of EGFR signaling, appears to be a negative effector of EGFR signaling during eye development. Further genetic analysis of the relationship between spen and nito in the eye suggests they function antagonistically, possibly by targeting a common set of genes for transcriptional regulation. Further analysis of SPOC family mutants and study of the functions of these proteins at a molecular level will be necessary to understand the relationship of small and large SPOC proteins and the roles of the proteins in development and disease.
Download or read book Using Transcriptomics to Identify Targets of Eyeless and Signaling Pathways in Drosophila Eye Development written by Nfsonsam Landry Ewongkem and published by . This book was released on 2012 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tissue-specific transcription factors cooperate with signaling pathways to promote specification, in part by co-regulating transcription. The Drosophila melanogaster Pax6 homolog Eyeless forms a complex, incompletely understood regulatory network with signaling pathways to control eye-specific gene expression. I employed mRNAseq and microarray approaches to identify targets co-regulated by Eyeless and Hedgehog, Decapentaplegic or Notch signals, to further understand the Drosophila eye network. The gene encoding the neprilysin family peptidase 'Abnormally blistered and morphologically misshapen eyes', Abams and the Drosophila class II 'Myosin heavy chain' protein, Mhc, were expressed at higher levels in the eye tissues versus wing tissues, and were highly expressed in eye tissues in response to Ey+N. Thus, both abams and Mhc were predicted to have roles in eye development. Whereas wild type eyes have a regular array of ommatidia interspersed with regularly occurring sensory bristles, using RNA interference (RNAi), I showed that reduction of abams function resulted in smaller eyes that consisted of patches of individual ommatidia surrounded by numerous bristles. Photoreceptor development was disrupted when abams function was reduced in eye precursors. Loss of function analyses and RNAi of Mhc revealed disruptions in the eye lattice and the mispositioning of photoreceptor nuclei within the eye precursor epithelium. My results suggest that Abams is involved in cell-cell signaling while Mhc regulates cell morphology and/or cell-cell adhesion during eye development. Transcription factor binding site (BS) analyses using computational modeling revealed [greater than or equal to] 94 other candidate genes as potential direct targets of Ey or Ey+Hh, Dpp or N. These included genes with already known roles in Drosophila eye development, as well as genes with unknown function, thus providing potential new directions to pursue to further understand the mechanism of interaction between Ey and Hh, Dpp or Notch during Drosophila eye development. Given the similarity between D. melanogaster and vertibrate eye development, further study of Abams and Mhc in Drosophila eye development will provide novel insights into our understanding of eye development in D. melanogaster and humans.

Available in PDF, EPUB and Kindle. Book excerpt: Vision is our primary sensory modality, and we are naturally curious as to how the visual system assembles. The visual system is in many ways remarkably simple, a repeating assemblage of neurons and support cells that parse the visual field through precision and redundancy. Through this simplicity the eye has often led the way in our exploration of how an organ is assembled. Eye development has therefore long been a favorite for exploring mechanisms of cell fate choice, patterning and cell signaling. This volume, which is part of the Current Topics in Developmental Biology series, highlights the exceptional advances over the past 20 years. Chapters emphasize our knowledge of transcription factors and how these generate networks to direct the eye field and associated structures. Topics such as cell fate specification are also explored, along with the potential of Drosophila as a model for lens formation and the progress made in using the Drosophila eye to examine planar cell polarity. Contributions from researchers who are active in identifying new paradigms to explore Review of our current state of knowledge Chapters written by authors with a new generation approach that takes a more systems approach to identifying factors and better defines cell subtypes
