The Role Of The Golgi Elmo Proteins In Cell Adhesion In Arabidopsis Thaliana, Wesley James Hudson
The Role Of The Golgi Elmo Proteins In Cell Adhesion In Arabidopsis Thaliana, Wesley James Hudson
Honors Projects
Proper growth and development of plant cells is dependent upon successful cell adhesion between cells, and this is mostly mediated by pectin in the plant cell wall. Previously, the Kohorn Laboratory identified a non-enzymatic Golgi protein named ELMO1 as it is required for cell adhesion, likely acting as a scaffold for cell wall polymer synthesis. Plants with mutant ELMO1 demonstrate a weak defective cellular adhesion phenotype as well as reduced mannose content in the cell wall. ELMO1 has homologous proteins in at least 29 different vascular plants. These homologues have 2 possible deletions in their amino acid sequence, but protein …
Mutual Benefits Of Inducible Defenses To Crab Predators In The Blue Mussel Mytilus Edulis In A Multi-Predator Environment, Sophia Walton
Mutual Benefits Of Inducible Defenses To Crab Predators In The Blue Mussel Mytilus Edulis In A Multi-Predator Environment, Sophia Walton
Honors Projects
The blue mussel Mytilus edulis alters its phenotype in species-specific ways in response to either green crab (Carcinus maenus) or sea star (Asterias sp.) predation. Previous studies have shown that only sea stars induce changes in abductor muscle morphology, while green crabs generally alter the shape and thickness of shells. In the Western Gulf of Maine, Blue mussels collected from wave protected sites with abundant green crab predators were shown to have significantly thicker shells and larger adductor muscles than mussels collected from wave exposed sites with few green crab predators. The phenotypes of mussels originating …

Aortic Pressure And Heart Rate In The Lobster Homarus Americanus Are Modulated By Mechanical Feedback And Neuropeptides, Grace Marie Hambelton
Aortic Pressure And Heart Rate In The Lobster Homarus Americanus Are Modulated By Mechanical Feedback And Neuropeptides, Grace Marie Hambelton
Honors Projects
Baroreceptors are stretch receptors located in the aorta of mammals; in response to increased afterload, they elicit a decrease in heart rate, creating a negative feedback loop that lowers blood pressure. Although lobsters (Homarus americanus) do not have baroreceptors like mammals, closely related land crabs have been shown to have baroreceptor-like responses. Heart contraction is also regulated by the Frank-Starling response, where increasing stretch or preload increases the contractile force of the heart. In addition to these types of biomechanical modulations, lobsters use a central pattern generator, the cardiac ganglion, to maintain synchronicity of the heartbeat. The heart …
Characterization Of Yellow Family Proteins In Gryllus Bimaculatus, Alexandra W. Rubenstein
Characterization Of Yellow Family Proteins In Gryllus Bimaculatus, Alexandra W. Rubenstein
Honors Projects
Neuronal plasticity occurs in developing nervous systems, with adult organisms rarely able to recover from neurological damage. The cricket, Gryllus bimaculatus, is useful to study neuronal plasticity due to its reorganization of the auditory system in response to injury beyond development. When a cricket ear is removed and auditory afferents severed, a rare phenomenon occurs: the dendrites of interneurons on the deafferented side cross the typically-respected midline of the prothoracic ganglion to form functional synapses with auditory afferents from the opposite side. To find proteins involved in this phenomenon, the Horch Lab assembled a de novo transcriptome from neurons in …
Natural Variation In Chromatin Conformation Among Populations Of Drosophila Melanogaster, Utku Ferah
Natural Variation In Chromatin Conformation Among Populations Of Drosophila Melanogaster, Utku Ferah
Honors Projects
The role of polymorphisms in protein-coding and non-coding regions of the genome during adaptive evolution has been a long-debated subject in evolutionary biology. Although the importance of coding-sequence polymorphisms during evolution has been well-documented, the influence of non-coding regions of the genome on phenotypic diversity and adaptive evolution remains less clear. Enhancers are cis-regulatory elements that dictate gene transcription rates, times, and locations; enhancers are located in noncoding regions and, when active, exhibit an open-chromatin conformation. In the current study, we identified putative enhancers that differ in chromatin conformation among three natural isolates of Drosophila melanogaster from different parts …
