A Transcriptomic Exploration Of Hawaiian Drosophilid Development And Evolution, Madeline M. Chenevert
A Transcriptomic Exploration Of Hawaiian Drosophilid Development And Evolution, Madeline M. Chenevert
University of New Orleans Theses and Dissertations
One in four known species of fruit flies inhabit the Hawaiian Islands. From a small number of colonizing flies, a wide range of species evolved, some of which managed to reverse-colonize other continental environments. In order to explore the developmental pathways, which separate the Hawaiian Drosophila proper and the Scaptomyza group that contains reverse-colonized species, the transcriptomes of two better-known species in each group, Scaptomyza anomala and Drosophila grimshawi, were analyzed to find changes in gene expression between the two groups. This study describes a novel transcriptome for S. anomala studies as well as unusual changes in gene expression …
The Functional Conservation Of Frazzled In Insects, Benjamin Wadsworth
The Functional Conservation Of Frazzled In Insects, Benjamin Wadsworth
Graduate Theses and Dissertations
Axons in the developing embryo receive and react to signals that direct their growth to reach target tissues at specified locations. The signal pathways that direct midline crossing of axons during embryonic development have been comprehensively examined in the past years using the Drosophila ventral nerve cord or the spinal cord as a model system. A number of these signaling mechanisms are conserved, however disparities have been found between species in general strategy or the molecular signals controlling the response of axons to guidance cues.
The Netrin-Frazzled pathway has been shown to aid in midline crossing of axons in the …

Effects Of Meiotic Drive On Developing Eye-Stalks In Stalk-Eyed Flies, Christopher Lepore, Olivia Smith, Heather Wood, Josephine Reinhardt Phd
McNair Scholars Program
Teleopsis dalmanni, commonly known as Stalk-Eyed flies, are known for their sexually dimorphic eye-stalks which females use to pick mates. Within the Gombak-12 population, some individuals contain meiotic drive which is known to influence eye-stalk length and sex ratios. Our goal was to identify genes in developing eye tissue that play a role in causing meiotic drive. To identify these candidate genes, we determined the sex and meiotic drive status of individuals by dissecting 3rd instar larvae for their carcasses. After finding that Qiagen Puregene and Qiagen DNEasy columns DNA extraction techniques worked best—determined by using gel electrophoresis—we prepared …
From Spinning Silk To Spreading Saliva: Mouthpart Remodeling In Manduca Sexta (Lepidoptera: Sphingidae), Istvan Miko, Sarthok Rasique Rahman, Anne C. Jones, Mark A. Townley, Brandon Gominho, Sulav Paudel, S David Stupski, Heather M. Hines, Rudolf J. Schilder

Biological Sciences
As a model organism, the tobacco hornworm Manduca sexta (Linnaeus 1763) has contributed much to our knowledge of developmental processes in insects, and major developmental changes between different larval instars are generally well understood. Second and later instars of M. sexta do not produce silk, and their spinneret and accessory labial glands (=Lyonet’s glands), structures thought to be key players in silk production in other lepidopterans, are highly reduced. To our knowledge, mouthparts and labial gland morphology of the silk-producing first instar have never been described. In this study, we compared the mouthpart morphology and transcriptome profile of first and …

Do Enallagma Exsulans From Streams And Lakes Show Patterns Of Divergence?, Savannah Rae Graham
Graduate Theses and Dissertations
Divergent selection across heterogenous environments could lead to adaptive divergence in populations resulting in potential local adaption. These populations have phenotypic differences that are fitness related and make native individuals more fit than non-native individuals. My research focuses on a species of damselfly, Enallagma exsulans, to explore local adaptation and morphological differences as a result of divergent selection or plasticity. My first study explored potential local adaptation of wild caught stream and lake E. exsulans using a reciprocal transplant design, a classic approach for this objective. The stream and lake sites chosen were on a small spatial scale allowing for …

Spinal Muscular Atrophy (SMA) is caused by homozygous mutations in the human survival motor neuron 1 (SMN1) gene. SMN protein has a well-characterized role in the biogenesis of small nuclear ribonucleoproteins (snRNPs), core components of the spliceosome. SMN is part of an oligomeric complex with core binding partners, collectively called Gemins. Biochemical and cell biological studies demonstrate that certain Gemins are required for proper snRNP assembly and transport. However, the precise functions of most Gemins are unknown. To gain a deeper understanding of the SMN complex in the context of metazoan evolution, we investigated its composition in Drosophila …
