Systematics Of Malesian-Pacific Piper (Piperaceae), Rani Asmarayani
Systematics Of Malesian-Pacific Piper (Piperaceae), Rani Asmarayani
Dissertations
Comprised of ~2400 spp., Piper is a major clade in the magnoliid angiosperms. Three major groups are recognized in Piper, i.e., the Neotropical, Asian and South Pacific. Unlike Neotropical Piper,relationships in the Paleotropical Piper remain enigmatic. This study focused on the Paleotropical Piperwith emphasize on the Malesian-Pacific Piper, Malesia being the center of diversity of the genus in the Paleotropics. The goals are to evaluate relationships within Paleotropical Piper (chapter 1), to evaluate characters, morphological (chapter 1) and stem anatomical (chapter 2), that may distinguish clades, and to investigate the species boundaries focusing on the well-supported …

Generating High-Order Optical And Spin Harmonics From Ferromagnetic Monolayers, G.P. Zhang, M.S. Si, M. Murakami, Y.H. Bai, Thomas George
Chemistry & Biochemistry Faculty Works
High-order harmonic generation (HHG) in solids has entered a new phase of intensive research, with envisioned band-structure mapping on an ultrashort time scale. This partly benefits from a flurry of new HHG materials discovered, but so far has missed an important group. HHG in magnetic materials should have profound impact on future magnetic storage technology advances. Here we introduce and demonstrate HHG in ferromagnetic monolayers. We find that HHG carries spin information and sensitively depends on the relativistic spin–orbit coupling; and if they are dispersed into the crystal momentum k space, harmonics originating from real transitions can be k-resolved and …

Evolution Of Bidirectional Costly Mutualism From Byproduct Consumption, Lon Chubiz, William Harcombe, Jeremy Chacón, Elizabeth Adamowicz, Christopher Marx
Biology Department Faculty Works
Mutualisms are essential for life, yet it is unclear how they arise. A two-stage process has been proposed for the evolution of mutualisms that involve exchanges of two costly resources. First, costly provisioning by one species may be selected for if that species gains a benefit from costless byproducts generated by a second species, and cooperators get disproportionate access to byproducts. Selection could then drive the second species to provide costly resources in return. Previously, a synthetic consortium evolved the first stage of this scenario: Salmonella enterica evolved costly production of methionine in exchange for costless carbon byproducts generated by …
Puf Proteins: Regulation Of Condition-Specific Mrna Decay And Contributions To Ribosome Biogenesis In Yeast, Anthony Fischer
Puf Proteins: Regulation Of Condition-Specific Mrna Decay And Contributions To Ribosome Biogenesis In Yeast, Anthony Fischer
Dissertations
Regulation of protein expression is critical to organism survival. Multiple disease states arise from aberrant accumulation/aggregation of proteins or reduced production of key enzymes. Cells have many ways to manipulate protein levels, including transcription factors, chromatin modification, modification of messenger RNA (mRNA), and manipulation of proteolytic protein decay. Cells can indirectly control protein volume by controlling mRNA lifespan, which is directly correlated with protein output. Often, sequence-specific elements in mRNA contribute to this lifespan. The Puf family of RNA-binding proteins is ubiquitous throughout eukarya, and plays important cellular and developmental roles through mRNA lifespan regulation. Puf proteins contain a C-terminal …
A Parallelized Implementation Of Cut-And-Solve And A Streamlined Mixed-Integer Linear Programming Model For Finding Genetic Patterns Optimally Associated With Complex Diseases, Michael Yip-Hin Chan
A Parallelized Implementation Of Cut-And-Solve And A Streamlined Mixed-Integer Linear Programming Model For Finding Genetic Patterns Optimally Associated With Complex Diseases, Michael Yip-Hin Chan
Theses
With the advent of genetic sequencing, there was much hope of finding the inherited elements underlying complex diseases, such as late-onset Alzheimer’s disease (AD), but it has been a challenge to fully uncover the necessary information hidden in the data. A likely contributor to this failure is the fact that the pathogenesis of most complex diseases does not involve single markers working alone, but patterns of genetic markers interacting additively or epistatically. But as we move upwards beyond patterns of size two, it quickly becomes computationally infeasible to examine all combinations in the solution space. A common solution to solving …
Multiple Puf Proteins Regulate The Stability Of Ribosome Biogenesis Transcripts, Anthony Fischer, Wendy Olivas
Multiple Puf Proteins Regulate The Stability Of Ribosome Biogenesis Transcripts, Anthony Fischer, Wendy Olivas
Biology Department Faculty Works
Cells must make careful use of the resources available to them. A key area of cellular regulation involves the biogenesis of ribosomes. Transcriptional regulation of ribosome biogenesis factor genes through alterations in histone acetylation has been well studied. This work identifies a post-transcriptional mechanism of ribosome biogenesis regulation by Puf protein control of mRNA stability. Puf proteins are eukaryotic mRNA binding proteins that play regulatory roles in mRNA degradation and translation via association with specific conserved elements in the 3ʹ untranslated region (UTR) of target mRNAs and with degradation and translation factors. We demonstrate that several ribosome biogenesis factor mRNAs …

The Brazilian Cerrado is one of the most endangered biomes in the world. We evaluated the sustainability of leaf harvest in one of the most important Cerrado tree species, Stryphnodendron adstringens. The bark of this tree is used as a source of medicinal tannin. Harvesting bark, however, often kills the tree. In a manipulative field experiment, we tested the hypothesis that harvesting leaves, which might serve as an alternative source of tannin, would be less detrimental for tree survival, growth, reproduction, and defense than harvesting bark. In a two-way crossed experimental design, we either clipped 100% of a plant’s leaves …
Haemosporidian Parasite Community In Migrating Bobolinks On The Galapagos Islands, Patricia Parker, Noah Perlut, Rosalind Renfrew, Maricruz Jaramillo
Haemosporidian Parasite Community In Migrating Bobolinks On The Galapagos Islands, Patricia Parker, Noah Perlut, Rosalind Renfrew, Maricruz Jaramillo
Biology Department Faculty Works
Bobolinks (Dolichonyx oryzivorus) migrate from their breeding grounds in North America to their wintering grounds in South America during the fall each year. A small number of Bobolinks stop temporarily in Galapagos, and potentially carry parasites. On the North American breeding grounds, Bobolinks carry a least two of the four Plasmodium lineages recently detected in resident Galapagos birds. We hypothesized that Bobolinks carried these parasites to Galapagos, where they were bitten by mosquitoes that then transmitted the parasites to resident birds. The haemosporidian parasite community in 44% of the Bobolinks we captured was consistent with those on their breeding grounds. …

Chemistry & Biochemistry Faculty Works
The established role of nematic liquid crystals (NLCs) in the recent rapid development of displays has motivated researchers to modulate the electro-optical properties of LCs. Furthermore, adding nanomaterials into NLCs has led to enhancements of the properties of NLCs, like reduced threshold of the operating voltage, variation in pretilt angle, reduced switching time, etc. These enhanced properties, due to interfacial dynamics, are enabling wider applications of NLCs and nanomaterials. The recent literature of nanomaterial-doped NLCs is rich with various kinds of nanomaterials in a variety of NLCs. The light has been focused on the most widely used and studied gold …
Transcriptomics Of Learning, Pablo Iturralde
Transcriptomics Of Learning, Pablo Iturralde
Theses
Learning is a basic and important component of behavior yet we have very little empirical information about the interaction between mechanisms of learning and evolution. In our work, we are testing hypotheses about the neurogenetic mechanisms through which animal learning abilities evolve. We are able to test this directly by using experimentally evolved populations of flies, which differ in learning ability. These populations were previously evolved within the lab by creating worlds with different patterns of change following theoretically predicted effects on which enhanced learning will evolve. How has evolution acted to modulate genes and gene expression in the brain …

Microvesicles (MVs) and exosomes comprise a class of cell-secreted particles termed extracellular vesicles (EVs). These cargo-holding vesicles mediate cell-to-cell communication and have recently been implicated in neurodegenerative diseases such as Alzheimer’s disease (AD). The two types of EVs are distinguished by the mechanism of cell release and their size, with the smaller exosomes and the larger MVs ranging from 30 to 100 nm and 100 nm to 1 μm in diameter, respectively. MV numbers are increased in AD and appear to interact with amyloid-β peptide (Aβ), the primary protein component of the neuritic plaques in the AD brain. Because microglial …
Investigation Of The Role Of Gene Clusters In Terpene Biosynthesis In Sorghum Bicolor, Rebecca Hay
Investigation Of The Role Of Gene Clusters In Terpene Biosynthesis In Sorghum Bicolor, Rebecca Hay
Theses
The staple crop Sorghum bicolor shows potential as a source of secondary metabolite-based biofuels due to its diverse phenotype and chemical profile. S. bicolor produces a variety of high-energy metabolites, including terpenes which are a potential renewable source of fuel additives. Information on the biosynthetic and genetic pathways by which S. bicolor terpenes are produced is limited and these pathways must be better understood before they can be engineered for human applications. Recent work on plant biosynthetic pathways has shown that terpenes can be modified by the products of clustered genes. Identification of biosynthetic gene clusters may accelerate the elucidation …

Roles Of Phospholipases And Ribosomal S6 Kinase In Lipid Remodeling And Growth In Arabidopsis Response To Phosphate Deprivation, Yuan Su
Dissertations
Phosphate (Pi) is one of three macronutrients for plants, which is vital for plant growth and development. Understanding the mechanism by which plants respond and adapt to Pi deficiency not only unveils functions of genes and pathways involved, but also provides potential tools to manipulate crops to better stand Pi stress in low Pi-containing lands. One of the significant metabolic changes in plants under Pi starvation is the membrane lipid remodeling that converts Pi-containing lipids such as phospholipids to Pi-free lipids, such as glycolipids. To elucidate the metabolism and regulation of lipid remodeling, this dissertation characterizes the role of two …

Interactions between species and their environment play a key role in the evolution of diverse communities, and numerous studies have emphasized that interactions among microbes and among trophic levels play an important role in maintaining microbial diversity and ecosystem functioning. In this study, we investigate how two of these types of interactions, public goods cooperation through the production of iron scavenging siderophores and predation by the social amoeba Dictyostelium discoideum, mediate competition between two strains of Pseudomonas fluorescens that were co-isolated from D. discoideum. We find that although we are able to generally predict the competitive outcomes between strains based …
The Ecology Of Nest Cavity Use By Arboreal Ants In The Brazilian Cerrado: Resource Availability, Nest Modification, And Trophic Interactions, Galen Priest
Dissertations
Arboreal ants in the Brazilian Cerrado rely on cavities in living trees as nest sites. These cavities are created by a community of, wood-boring beetles, which act as ecosystem engineers. Despite the importance of these cavities as a resource, little is known about their natural abundance and heterogeneity, how ants use and modify them as nest sites, and how this interaction between cavities and their ant occupants influences trophic interactions on cerrado trees. Here I use natural history observations and manipulative experiments to address these questions. In the first chapter I quantified the occurrence, heterogeneity, and use of beetle-created cavities …

Dna Binding Kinetics Of Large Antiviral Hairpin Polyamides, Jacquelyn Niederschulte
Dissertations
While vaccines exist for the some of the most problematic strains of human papillomavirus (HPV), a double stranded DNA virus, there is currently no cure. HPV remains one of the most commonly sexually transmitted infections and is responsible for virtually all cervical cancers and genital warts. Natural products Distamycin A and netropsin have inspired the hairpin Nmethylpyrrole (Py)/N-methylimidazole (Im) polyamides (PAs) studied here. The larger hairpin PAs, designed to bind to sites of 10 or more DNA bp, have been shown to be effective antivirals against oncogenic HPV strains 16, 18, and 31, while smaller hairpin PAs are not. Despite …

Efficient Reduced Bias Genetic Algorithm For Generic Community Detection Objectives, Aditya Karnam Gururaj Rao
Theses
The problem of community structure identification has been an extensively investigated area for biology, physics, social sciences, and computer science in recent years for studying the properties of networks representing complex relationships. Most traditional methods, such as K-means and hierarchical clustering, are based on the assumption that communities have spherical configurations. Lately, Genetic Algorithms (GA) are being utilized for efficient community detection without imposing sphericity. GAs are machine learning methods which mimic natural selection and scale with the complexity of the network. However, traditional GA approaches employ a representation method that dramatically increases the solution space to be searched by …

Backward electromagnetic waves are extraordinary waves with contra-directed phase velocity and energy flux. Unusual properties of the coherent nonlinear optical coupling of the phase-matched ordinary and backward electromagnetic waves with contra-directed energy fluxes are described that enable greatly-enhanced frequency and propagation direction conversion, parametrical amplification, as well as control of shape of the light pulses. Extraordinary transient processes that emerge in such metamaterials in pulsed regimes are described. The results of the numerical simulation of particular plasmonic metamaterials with hyperbolic dispersion are presented, which prove the possibility to match phases of such coupled guided ordinary and backward electromagnetic waves. Particular …
The Ecology And Feeding Behavior Of Mosquitoes In The Galapagos Islands, Samoa S. Asigau
The Ecology And Feeding Behavior Of Mosquitoes In The Galapagos Islands, Samoa S. Asigau
Dissertations
Mosquitoes remain important vectors in transmitting wildlife diseases. This dissertation aims to understand the role that mosquitoes play in transmitting wildlife diseases such as avian malaria, a protozoan parasite belonging to the genus Plasmodium. Using data from wild-caught mosquitoes captured in multiple years and across multiple islands on the Galapagos Archipelago, we describe distributional patterns of mosquitoes, their range limits and assess whether there exists a disease-free refuge as occurs in Hawaii. We show that altitudinal ranges for disease transmission of avian malaria may not be bounded by a stable disease-free refuge, since mosquitoes are found at all elevations, …
Interactions And Pathogen Transmission Between Carnivores In Madagascar, Fidisoa Rasambainarivo
Interactions And Pathogen Transmission Between Carnivores In Madagascar, Fidisoa Rasambainarivo
Dissertations
Introduced carnivores exert considerable pressure on native predators through predation, competition and disease transmission. Improved understanding of determinant factors of interactions and pathogen transmission between introduced and endemic wildlife may help to predict disease emergence, avoid pathogen spillover and help control outbreaks. Using non-invasive camera traps, I identified areas where transmission of pathogens might happen through records of shared space-use within a protected area in Eastern Madagascar. I showed that indirect interactions between animals were more likely to occur near the research station which may constitute a disease transmission hotspot for carnivores in the landscape. Secondly, I investigated the associations …

Biology Department Faculty Works
Peroxisomes are eukaryotic organelles critical for plant and human development because they house essential metabolic functions, such as fatty acid β-oxidation. The interacting ATPases PEX1 and PEX6 contribute to peroxisome function by recycling PEX5, a cytosolic receptor needed to import proteins targeted to the peroxisomal matrix. Arabidopsis pex6 mutants exhibit low PEX5 levels and defects in peroxisomal matrix protein import, oil body utilization, peroxisomal metabolism, and seedling growth. These defects are hypothesized to stem from impaired PEX5 retrotranslocation leading to PEX5 polyubiquitination and consequent degradation of PEX5 via the proteasome or of the entire organelle via autophagy. We recovered a …

Environmental factors strongly influence the ecology and evolution of vector‐borne infectious diseases. However, our understanding of the influence of climatic variation on host–parasite interactions in tropical systems is rudimentary. We studied five species of birds and their haemosporidian parasites (Plasmodium and Haemoproteus) at 16 sampling sites to understand how environmental heterogeneity influences patterns of parasite prevalence, distribution, and diversity across a marked gradient in water availability in northern South America. We used molecular methods to screen for parasite infections and to identify parasite lineages. To characterize spatial heterogeneity in water availability, we used weather‐station and remotely sensed climate data. We …

Thermodynamics In Large Hairpin Polyamide-Dna Interactions, Yang Song
Dissertations
Human papillomavirus (HPV) is a common sexually transmitted virus responsible for cervical cancers, and its infection is currently incurable. Only a few vaccines against high-risk HPV strains are available. Hairpin polyamides (PAs) in different sizes (8-20 units long) bind DNA in different lengths. They have been shown to have different anti-HPV activities in cell culture.
The interaction between PA and DNA is stabilized by two types of molecular forces: attractive and repulsive forces. Attractive forces include hydrogen bonds, van der Waals contacts and electrostatic forces between PA and DNA. Repulsive forces include the hydrophobic effect, which forces the PA out …
Haemosporidian Parasites And Host Immune Function Of Galapagos Avifauna, Maricruz Jaramillo
Haemosporidian Parasites And Host Immune Function Of Galapagos Avifauna, Maricruz Jaramillo
Dissertations
The large number of emergent infectious diseases witnessed in the past few decades has increased interest in the ecology and distribution of potentially threatening pathogens worldwide. Island species are often considered more vulnerable to parasites due to their impoverished parasite communities, long isolation from disease and low genetic diversity. Avian surveys done by our group on the Galapagos Islands have found various pathogens infecting their endemic avifauna, including haemosporidian parasites of the genera Plasmodium and Haemoproteus. My research seeks to understand the relationships between two haemosporidian parasites (blood parasites) and their multiple bird hosts in Galapagos and to explore …

Haemosporidians are a diverse group of vector-borne parasitic protozoa that includes the agents of human malaria; however, most of the described species are found in birds and reptiles. Although our understanding of these parasites’ diversity has expanded by analyses of their mitochondrial genes, there is limited information on these genes’ evolutionary rates. Here, 114 mitochondrial genomes (mtDNA) were studied from species belonging to four genera: Leucocytozoon, Haemoproteus, Hepatocystis, and Plasmodium. Contrary to previous assertions, the mtDNA is phylogenetically informative. The inferred phylogeny showed that, like the genus Plasmodium, the Leucocytozoon and Haemoproteus genera are not monophyletic groups. Although sensitive to …

BackgroundMitochondria play a key role in the balance of energy and heat production, and therefore the mitochondrial genome is under natural selection by environmental temperature and food availability, since starvation can generate more efficient coupling of energy production. However, selection over mitochondrial DNA (mtDNA) genes has usually been evaluated at the population level. We sequenced by NGS 12 mitogenomes and with four published genomes, assessed genetic variation in ten penguin species distributed from the equator to Antarctica. Signatures of selection of 13 mitochondrial protein-coding genes were evaluated by comparing among species within and among genera (Spheniscus, Pygoscelis, Eudyptula, Eudyptes and …

Plant drought stress causes systematic changes to photosynthesis, metabolism, growth, and potentially the phytobiome. Additionally, drought affects plants in both a species-specific and water-deficit-driven manner, causing the response to drought to be dependent both on how drought is being experienced and on any adaptation to prior drought exposure. Thus, understanding the effect of drought on plants requires assessing drought response in multiple conditions, such as progressive acute drought and recurrent cyclic drought, and at different levels of severity. In this study, we have utilized RNA sequencing to identify changes to the plant transcriptome and the phytobiome during both acute progressive …
