Abstract

<div class="line" id="line-7"> <span style='font-family: "Calibri","sans-serif"; font-size: 11pt;'> The development of the compound eye of </span> <i> <span style='font-family: "Calibri","sans-serif"; font-size: 11pt;'> Drosophila </span> </i> <span style='font-family: "Calibri","sans-serif"; font-size: 11pt;'> is controlled, in part, by the concerted actions of several nuclear proteins that form an intricate regulatory system. One member of this network is </span> <i> <span style='font-family: "Calibri","sans-serif"; font-size: 11pt;'> sine oculis </span> </i> <span style='font-family: "Calibri","sans-serif"; font-size: 11pt;'> ( </span> <i> <span style='font-family: "Calibri","sans-serif"; font-size: 11pt;'> so </span> </i> <span style='font-family: "Calibri","sans-serif"; font-size: 11pt;'> ), the founding member of the Six gene family. Mutations within </span> <i> <span style='font-family: "Calibri","sans-serif"; font-size: 11pt;'> so </span> </i> <span style='font-family: "Calibri","sans-serif"; font-size: 11pt;'> affect the entire visual system, including the compound eye. The vertebrate homologs Six3 and Six6 also appear to play crucial roles in retinal formation. Mutations in Six3 inhibit retinal formation in chickens and fish, whereas those in Six6 are the underlying cause of bilateral anophthalmia in humans. Together, these phenotypes suggest a conserved role for the Six genes in eye development. In this report, we describe the effects of a dominant&hyphen;negative mutation of </span> <i> <span style='font-family: "Calibri","sans-serif"; font-size: 11pt;'> sine oculis </span> </i> <span style='font-family: "Calibri","sans-serif"; font-size: 11pt;'> on the development of the compound eye of </span> <i> <span style='font-family: "Calibri","sans-serif"; font-size: 11pt;'> Drosophila </span> </i> <span style='font-family: "Calibri","sans-serif"; font-size: 11pt;'> . The mutation resides within the Six domain and may have implications for eye development and disease. </span></div>
