Characterization Of Waxy Grain Sorghum Lines In Relation To Granule-Bound Starch Synthase, J. F. Pedersen, S. R. Bean, R. A. Graybosch, S. H. Park, M. Tilley
Characterization Of Waxy Grain Sorghum Lines In Relation To Granule-Bound Starch Synthase, J. F. Pedersen, S. R. Bean, R. A. Graybosch, S. H. Park, M. Tilley
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
The waxy phenotype, associated with endosperm containing little or no amylose, has been recognized in sorghum (Sorghum bicolor L. Moench) since 1933. Although variants of the waxy gene are well characterized in other cereals, the waxy trait has been assumed to be controlled by a single allele, wx, in sorghum. Recent improvements in technologies encourage re-examination of the waxy sorghums. The objectives of this research were therefore to identify and characterize sorghum lines with differing waxy alleles and to describe the actions of those alleles in crosses. Grain of eight waxy sorghum lines (BTxARG1, BTx630, Tx2907, B.9307, 94C274, …

Distribution Of Hydrogen Peroxide In The Northwest Pacific Ocean, Jinchun Yuan, Alan M. Shiller
Faculty Publications
[1] Hydrogen peroxide (H2O2) is a reactive oxygen intermediate involved in the cycling of metals and dissolved organic matter. Because little is known of its distribution in the North Pacific Ocean, we determined H2O2 in surface waters continuously and obtained vertical profiles at nine stations during a cruise from Japan to Hawaii. Surface water H2O2 varied from less than 10 to more than 250 nmol dm(-3). A diel cycle in surface water H2O2 (similar to 25 nmol dm(-3)) was observed only on one day during the monthlong cruise. This is contrary to expectations based on the usual assumption of photo-production …

Biotinylation Of K12 In Histone H4 Decreases In Response To Dna Double-Strand Breaks In Human Jar Choriocarcinoma Cells1,2, Nagarama Kothapalli, Gautam Sarath, Janos Zempleni
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
We tested the hypothesis that biotinylation of K12 in histone H4 plays a role in the cellular response to double-strand breaks (DSB) of DNA in human cells. DSB were caused by treating choriocarcinoma JAr cells with etoposide. Biotinylation of K12 in histone H4 decreased by 50% as early as 10–20 min after initiation of treatment with etoposide. Biotinylation returned to initial levels 30–40 min after the addition of etoposide to the medium. Temporal patterns of K12-biotinylation were similar for human lymphoma cells. Phosphorylation of S14 of histone H2B and poly(ADP-ribosylation) of glutamate residues on histone H2A are known markers of …

Telomere Structure And Shortening In Telomerase-Deficient Trypanosoma Brucei, Oliver Dreesen, Bibo Li, George A.M. Cross
Biological, Geological, and Environmental Faculty Publications
Telomerase consists of a reverse transcriptase (TERT) and an RNA that contains a template for telomere-repeat extension. Telomerase is required to prevent telomere erosion and its activity or lack thereof is important for tumorigenesis and ageing. Telomerase has been identified in numerous organisms but it has not been studied in kinetoplastid protozoa. Trypanosoma brucei, the causative agent of African sleeping sickness, evades the host immune response by frequently changing its variant surface glycoprotein (VSG). The single expressed VSG is transcribed from one of ∼20 subtelomeric 'Expression Sites', but the role telomeres might play in regulating VSG transcription and switching is …

Characterization Of A Novel Filarial Serine Protease Inhibitor, Ov-Spi-1, From Onchocerca Volvulus, With Potential Multifunctional Roles During Development Of The Parasite, Louise Ford, David B. Guiliano, Yelena Oksov, Asim K. Debnath, Jing Liu, Steven A. Williams, Mark L. Blaxter, Sara Lustigman
Biological Sciences: Faculty Publications
A novel filarial serine protease inhibitor (SPI) from the human parasitic nematode Onchocerca volvulus, Ov-SPI-1, was identified through the analysis of a molting third-stage larvae expressed sequence tag dataset. Subsequent analysis of the expressed sequence tag datasets of O. volvulus and other filariae identified four other members of this family. These proteins are related to the low molecular weight SPIs originally isolated from Ascaris suumwhere they are believed to protect the parasite from host intestinal proteases. The two Ov-spi transcripts are up-regulated in the molt- ing larvae and adult stages of the development of the parasite. Recombinant Ov-SPI-1 is an …

The Optimal Discovery Procedure: A New Approach To Simultaneous Significance Testing, John D. Storey
The Optimal Discovery Procedure: A New Approach To Simultaneous Significance Testing, John D. Storey
UW Biostatistics Working Paper Series
Significance testing is one of the main objectives of statistics. The Neyman-Pearson lemma provides a simple rule for optimally testing a single hypothesis when the null and alternative distributions are known. This result has played a major role in the development of significance testing strategies that are used in practice. Most of the work extending single testing strategies to multiple tests has focused on formulating and estimating new types of significance measures, such as the false discovery rate. These methods tend to be based on p-values that are calculated from each test individually, ignoring information from the other tests. As …

Fractals Analysis Of Cardiac Arrhythmias, Mohammed Saeed
Fractals Analysis Of Cardiac Arrhythmias, Mohammed Saeed
Department of Biological & Biomedical Sciences
Heart rhythms are generated by complex self-regulating systems governed by the laws of chaos. Consequently, heart rhythms have fractal organization, characterized by self-similar dynamics with long-range order operating over multiple time scales. This allows for the self-organization and adaptability of heart rhythms under stress. Breakdown of this fractal organization into excessive order or uncorrelated randomness leads to a less-adaptable system, characteristic of aging and disease. With the tools of nonlinear dynamics, this fractal breakdown can be quantified with potential applications to diagnostic and prognostic clinical assessment. In this paper, I review the methodologies for fractal analysis of cardiac rhythms and …

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Switchgrass is a large, North American, perennial grass that is being evaluated as a potential energy crop. Expressed sequence tags (ESTs) were generated from four switchgrass cv. ‘‘Kanlow’’ cDNA libraries to create a gene inventory of 7,810 unique gene clusters from a total of 11,990 individual sequences. Blast similarity searches to SwissProt and GenBank non-redundant protein and nucleotide databases were performed and a total of 79% of these unique clusters were found to be similar to existing protein or nucleotide sequences. Tentative functional classification of 61% of the sequences was possible by association with appropriate gene ontology descriptors. Significant differential …

How microtubules act to position the plane of cell division during cytokinesis is a topic of much debate. Recently, we showed that a subpopulation of stable microtubules extends past chromosomes and interacts with the cell cortex at the site of furrowing, suggesting that these stabilized microtubules may stimulate contractility. To test the hypothesis that stable microtubules can position furrows, we used taxol to rapidly suppress microtubule dynamics during various stages of mitosis in PtK1 cells. Cells with stabilized prometaphase or metaphase microtubule arrays were able to initiate furrowing when induced into anaphase by inhibition of the spindle checkpoint. In these …

Hemoglobin (Hb) is a Highly Conserved Protein that Provides a Vital Link between Environmental Oxygen and its Use And/or Storage within an Organism. While Ubiquitous among Vertebrates, Hb Occurs Frequently in Invertebrate Phyla as Well. Many Arthropod Species Use the Copper-Binding Pigment Hemocyanin, But Unique in This Phylum Are the Branchiopod Crustaceans, Which Express Hb. Branchiopod Hb Concentration and Structure Are Exquisitely Sensitive to Environmental Oxygen Availability. Hemoglobin Concentration and Oxygen-Binding Affinity Increase with Decreasing Oxygen Tension in Daphnia, Artemia and Triops. the Change in Binding Affinity is Attributed to Differential Hb Subunit Expression in Daphnia and Artemia But Remains …

Two genera and Þve species of valgine scarabs (Cetoniinae: Valgini) are found in the New World, including the introduced European species, Valgus hemipterus L.. Valgus mexicanus Cazier is transferred to the genus Dasyvalgus Kolbe, and characters that support this transfer are discussed. Based on shared morphological characters, Valgus minutus Casey and V. serricollis Fitch are synonymized with V. canaliculatus (Olivier). Neotypes are designated for V. serricollis Fitch and Cetonia canaliculata Olivier.Akey to the genera and species of New World Valgini is provided. Species are redescribed and information about geographic and phenology, biology, and larvae is provided.

As much of the focus of genetics and molecular biology has shifted toward the systems level, it has become increasingly important to accurately extract biologically relevant signal from thousands of related measurements. The common property among these high-dimensional biological studies is that the measured features have a rich and largely unknown underlying structure. One example of much recent interest is identifying differentially expressed genes in comparative microarray experiments. We propose a new approach aimed at optimally performing many hypothesis tests in a high-dimensional study. This approach estimates the Optimal Discovery Procedure (ODP), which has recently been introduced and theoretically shown …
