Summary
The process of developmental of the eye of Drosophila is an important tool for understanding growth and pattern formation of tissues (from poster provided). Cellular interactions and intercellular signaling play a crucial role in this process. In the primary third instar stage an upsurge of differentiation sweeps from the posterior side to the anterior side of the eye disc. The advancing region of this wave is characterized by a morphogenetic furrow (MF), which leads the wave through production of decapentaplegic Dpp and Hh proteins, which subsequently activate the transcription of RD genes. The Dpp serves as a morphogen that plays a significant role in the proliferation and commencement of pattern formation. It functions in the advancement of the morphogenetic furrow in the eye and are necessary for dorsal ventral patterning of the drosophila embryo. The RD genes attach to enhancers and turn on the expression of certain genes at definite time points during development (from poster provided).
In this study, the researchers have sought out to examine nine different dpp cell lines with the goal of identifying eye specific enhancers (from poster provided). They have proposed to investigate and describe upstream enhancer sequences regulating dpp generation in the third instar of the imaginal disc in the eye and the pupal retina.
The enhancer lines produced in this study may be employed at particular regions limited to a small centralized area and for appropriate regulation of gene expression for prospective experiments. They will represent an important repository to disclose the complex genetic pyramid of eye development. Forthcoming experiments include exploring further into the expression status of these enhancers during eye development (from poster provided).
However, the body of the poster entails headings to separate out the background information, materials and methods and results of the study (from poster provided). The methods and materials used should have been discussed as a separate section with more emphasis than what is included in the poster. While the significance of these cell lines is states in the future directions, some more details regarding the use of these cell lines and future details would have completed the picture. Another major flaw in the poster is the poor organization of the sections, since the flow of the text is difficult to interpret. A bibliography of references appended to the end of the poster would have been good.
