Discovering Genes Involved In The Synthesis Of Secondary Metabolites From The Seeds Of Moringa Oleifera Through Transcriptome Analysis, Vivian A. Panes, Ma. Divina Kristi A. Discar

Biology Faculty Publications

Moringa oleifera is a widely used crop that produces seeds with a plethora of benefits encompassing health and nutrition. Secondary metabolite compounds were determined in the seeds of Moringa oleifera that possess nutritional and pharmacological benefits. Although various phytochemical researchers reported the presence of secondary metabolites in M. oleifera seeds, there is a lack of research on the genes encoding for enzymes that catalyze the synthesis of secondary metabolites in the seeds of M. oleifera. In the present study, RNA sequencing was used to analyze the transcriptome of the mature seed embryos of M. oleifera. Biological pathway analysis …

De Novo Assembly Of The Burying Beetle Nicrophorus Orbicollis (Coleoptera: Silphidae) Transcriptome Across Developmental Stages With Identification Of Key Immune Transcripts, Harim Won, Thomas T. Schulze, Emalie J. Clement, Gabrielle F. Watson, Sean M. Watson, Rosalie C. Warner, Elizabeth A. M. Ramler, Elias J. Witte, Mark A. Schoenbeck, Claudia M. Rauter, Paul H. Davis

Burying beetles (Nicrophorus spp.) are among the relatively few insects that provide parental care while not belonging to the eusocial insects such as ants or bees. This behavior incurs energy costs as evidenced by immune deficits and shorter life-spans in reproducing beetles. In the absence of an assembled transcriptome, relatively little is known concerning the molecular biology of these beetles. This work details the assembly and analysis of the Nicrophorus orbicollis transcriptome at multiple developmental stages. RNA-Seq reads were obtained by next-generation sequencing and the transcriptome was assembled using the Trinity assembler. Validation of the assembly was performed by functional …

Analysis Of The Oil Biosynthesis Transcripts Of The Moringa Oleifera Lam. Mature Seed Embryos Using Rna Sequencing, Vivian A. Panes, A Kitazumi, M Butler, R.D Baoas, B.G De Los Reyes

Biology Faculty Publications

Moringa oleifera seeds are capable of producing 40% edible oils that are gaining significance due to its nutritional advantages. Several studies have examined M. oleifera seed oil, nevertheless, these studies focused on the extraction of oil and methods of biodiesel production. There is a paucity of information on transcriptome level studies to determine the unigenes involved in oil biosynthesis metabolic pathways. The main objective of this study is to explore the transcriptome of the mature embryo of M. oleifera Lam. particularly the key genes related to oil biosynthesis. The transcriptome reflects the set of genes that are actively expressed at …

Characterizing The Neurotranscriptomic States In Alternative Stress Coping Styles, Ryan Y. Wong, Melissa S. Lamm, John Godwin

Biology Faculty Publications

Background: Animals experience stress in many contexts and often successfully cope. Individuals exhibiting the proactive versus reactive stress coping styles display qualitatively different behavioral and neuroendocrine responses to stressors. The predisposition to exhibiting a particular coping style is due to genetic and environmental factors. In this study we explore the neurotranscriptomic and gene network biases that are associated with differences between zebrafish (Danio rerio) lines selected for proactive and reactive coping styles and reared in a common garden environment.

Results: Using RNA-sequencing we quantified the basal transcriptomes from the brains of wild-derived zebrafish lines selectively bred to exhibit the proactive …

Limited Sex-Biased Neural Gene Expression Patterns Across Strains In Zebrafish (Danio Rerio), Ryan Y. Wong, Melissa M. Mcleod, John Godwin

Biology Faculty Publications

Background: Male and female vertebrates typically differ in a range of characteristics, from morphology to physiology to behavior, which are influenced by factors such as the social environment and the internal hormonal and genetic milieu. However, sex differences in gene expression profiles in the brains of vertebrates are only beginning to be understood. Fishes provide a unique complement to studies of sex differences in mammals and birds given that fish show extreme plasticity and lability of sexually dimorphic characters and behaviors during development and even adulthood. Hence, teleost models can give additional insight into sexual differentiation. The goal of …

De Novo Assembly And Analysis Of The Northern Leopard Frog Rana Pipiens Transcriptome, Matthew K. Christenson, Andrew J. Trease, Lakshmi-Prasad Potluri, Andrew Jezewski, Vincent M. Davis, Lindsey A. Knight, Alan Kolok, Paul H. Davis

Biology Faculty Publications

The northern leopard frog Rana (Lithobates) pipiens is an important animal model, being used extensively in cancer, neurology, physiology, and biomechanical studies. R. pipiens is a native North American frog whose range extends from northern Canada to southwest United States, but over the past few decades its populations have declined significantly and is now considered uncommon in large portions of the United States and Canada. To aid in the study and conservation of R. pipiens, this paper describes the first R. pipiens transcriptome. The R. pipiens transcriptome was annotated using Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), …

Transcriptome Analysis Of Two Buffalograss Cultivars, Michael Wachholtz, Tiffany Heng-Moss, Paul Twigg, Lisa Baird, Guoqing Lu, Keenan Amundsen

Biology Faculty Publications

Background: Buffalograss [Buchloë dactyloides (Nutt.) Engel. syn. Bouteloua dactyloides (Nutt.) Columbus] is a United States native turfgrass species that requires less irrigation, fungicides and pesticides compared to more commonly used turfgrass species. In areas where water is limited, interest in this grass species for lawns is increasing. While several buffalograss cultivars have been developed through buffalograss breeding, the timeframe for new cultivar development is long and is limited by a lack of useful genetic resources. Two high throughput next-generation sequencing techniques were used to increase the genomic resources available for buffalograss.

Results: Total RNA was extracted and …
