The Impact of Surface Ocean Mixing on Phytoplankton Communities and Associated Carbon Pools

Creator:: VerWey, Brian J.
Abstract:: Deep mixing events in the ocean’s surface layer act as physical drivers of carbon export by detraining dissolved and particulate organic matter, including surface phytoplankton communities, to depth. Once removed from the sunlit surface ocean environment, phytoplankton accumulation rates are dependent on the relative contributions of loss processes, such as...

Constructing a gene expression atlas of Chia (Salvia hispanica)

Creator:: Phillips, Jeremy Levi, Geniza, Matthew, Haq, Ebaad, and Jaiswal, Pankaj
Abstract:: • Salvia hispanica, also known as Chia, is an annual plant of the mint family, Lamiaceae. Chia is a vascular plant with perennating buds initially formed at or within the soil surface. Chia grows to roughly one meter tall at maturity, with leaves growing in opposite arrangement, small purple flowers,...

The Seed Cone Eathiestrobus gen. nov.: Fossil Evidence for a Jurassic Origin of Pinaceae

Creator:: Rothwell, Gar W., Mapes, Gene, Stockey, Ruth A., and Hilton, Jason
Abstract:: Premise of the study: Pinaceae and nonpinoid species are sister groups within the conifer clade as inferred from molecular systematic comparisons of living species and therefore should have comparable geological ages. However, the fossil record for the nonpinoid lineage of extant conifer families is Triassic, nearly 100 million years older...

Diversity of ancient conifers: The jurassic seed cone bancroftiastrobus digitata gen. et sp. nov. (coniferales)

Creator:: Rothwell, Gar W., Mapes, Gene, Stockey, Ruth A., and Hilton, Jason
Abstract:: Premise of research. A third genus of anatomically preserved conifer seed cones has been recognized from a Late Jurassic deposit in northeastern Scotland. This cone is described as Bancroftiastrobus digitata Rothwell, Mapes, Stockey et Hilton. Methodology. The cone was sectioned with the classic coal ball peel technique and studied and...

Distribution of Potato virus Y Strains in Tubers during the Post-Harvest Period

Creator:: Whitworth, Jonathan L., Hamm, Philip B., and Nolte, Phillip
Abstract:: Russet Burbank, Russet Norkotah, and Shepody tubers infected with Potato virus Y strains (PVYO, PVYN:O, PVYNTN) were tested from storage at 4A degrees C at the initiation of sprouting and then the same tubers were tested again from storage at 4A degrees C seventy eight days later. Samples were taken...

Small secreted proteins of pyrenophora tritici-repentis and their role in wheat Infection

Creator:: Hernandez, Jason, Manning, Viola, Pandelova, Iovanna, and Ciuffetti, Lynda M.
Abstract:: Host-selective toxins (HSTs) secreted by the pathogenic isolate of Pyrenophora tritici-repentis, BFP, are major pathogenicity factors in tan spot disease of wheat. Along with characterized HSTs such as Ptr ToxA (ToxA), BFP secretes at least two more uncharacterized toxic components. In an attempt to identify these additional components, 12 candidate...

Reconsidering Relationships among Stem and Crown Group Pinaceae: Oldest Record of the Genus Pinus from the Early Cretaceous of Yorkshire, United Kingdom

Creator:: Ryberg, Patricia E., Rothwell, Gar W., Stockey, Ruth A., Hilton, Jason, Mapes, Gene, and Riding, James B.
Abstract:: This study describes a specimen that extends the oldest fossil evidence of Pinus L. to the Early Cretaceous Wealden Formation of Yorkshire, UK (131-129 million years ago), and prompts a critical reevaluation of criteria that are employed to identify crown group genera of Pinaceae from anatomically preserved seed cones. The...

Genome-Wide Profiling and Analysis of Arabidopsis siRNAs

Creator:: Kasschau, Kristin D., Fahlgren, Noah, Chapman, Elisabeth J., Sullivan, Christopher M., Cumbie, Jason S., Givan, Scott A., and Carrington, James C.
Abstract:: Eukaryotes contain a diversified set of small RNA-guided pathways that control genes, repeated sequences, and viruses at the transcriptional and posttranscriptional levels. Genome-wide profiles and analyses of small RNAs, particularly the large class of 24-nucleotide (nt) short interfering RNAs (siRNAs), were done for wild-type Arabidopsis thaliana and silencing pathway mutants...

Length Bias Correction in Gene Ontology Enrichment Analysis Using Logistic Regression

Creator:: Mi, Gu, Di, Yanming, Emerson, Sarah, Cumbie, Jason S., and Chang, Jeff H.
Abstract:: When assessing differential gene expression from RNA sequencing data, commonly used statistical tests tend to have greater power to detect differential expression of genes encoding longer transcripts. This phenomenon, called "length bias", will influence subsequent analyses such as Gene Ontology enrichment analysis. In the presence of length bias, Gene Ontology...

Litter decay processes and soil nitrogen availability in native and cheatgrass-dominated arid rangelands

Creator:: Harrison, Kristen S.
Abstract:: As large-scale restorations of degraded rangelands are initiated, land managers need to understand how decades of dominance by the invasive annual grass, cheatgrass (Bromus tectorum L.), have altered ecosystem processes. One way to assess such alterations is by observing differences in decay rates, since decomposition is determined by factors such...
