Impact Of Winter Cover Crops And Nitrogen Recommendations For Corn-Soybean Rotation In Northeast Arkansas, Brayden William Burns

Student Theses and Dissertations

Research plots were established on production farms in no-tillage, corn-soybean rotations following a winter cover crop. Independent variables included fertilizer N-application (0, 62, 124, 185, 247 and 309 kg N ha-1) and the presence or absence of a winter cover crop. Yield optimum nitrogen rates (YONR) estimated using linear plateau models ranged from 69.7 to 214.1 kg N ha-1, well below the University of Arkansas’ recommendation of 247 kg N ha-1. Relative to these YONRs, dynamic N-recommendation systems like N-Star, and pre-sidedress available nitrogen (PSAN) reduced recommended N-application rate with little risk of insufficient N-supply. Other recommendations like the Soil …

Investigation Of The State Of Dna Methylation In High And Low Protein Accumulating Maize Lines, Akash Lal

Student Theses and Dissertations

Transgenic plant-based production for industrial enzymes is an evolutionary tool. Green bio- factories have powerful potential to produce desirable product on the most economical and efficient level. Seed itself provides protein a very stable environment, solving the problem of storage. Transgenic plants easily scale up production. Increasing population, climate change and low amounts of arable land create a damaging situation for which a plant-based production system is beneficial. The transgenic plant-based production system rather than microbial fermentation is a solution for this rising scenario. Epigenetics is a natural phenomenon which causes heritable changes in gene expression alternative to the involvement …

Pando: Charismatic Megaflora And The Populus Paradox, Paul C. Rogers, Lance Oditt

Aspen Bibliography

Within the field of landscape ecology, the Pando aspen grove on the Fishlake National Forest of Utah is legendary—and it is in danger of dying from hotter, drier temperatures and other threats. Pando is one of the largest and oldest known still-living organisms on Earth. Quaking aspen are an important tree species in Greater Yellowstone and the Rocky Mountain West. Enjoy this essay written by a scientist who studies Pando and a photographer who celebrates this arboreal mega-being.

The Annual Rhythmic Differentiation Of Populus Davidiana Growth–Climate Response Under A Warming Climate In The Greater Hinggan Mountains, Ruixin Yun, Yuting Jin, Junxia Li, Zhenju Chen, Zhaoyang Lyu, Ying Zhao, Di Cui

Aspen Bibliography

The stability and balance of forest ecosystems have been seriously affected by climate change. Herein, we use dendrochronological methods to investigate the radial growth and climate response of pioneer tree species in the southern margin of cold temperate coniferous forest based on Populus davidiana growing on the Greater Hinggan Mountains in northeastern China. Correlations of P. davidiana growth with temperature and precipitation in a year (October–September) were rhythmically opposed: while temperatures in previous October–June (winter and spring) and in May–September (growing season) respectively inhibited and promoted radial growth on P. davidiana (p < 0.01), precipitation in the same periods respectively promoted and inhibited of growth (p < 0.01). High temperature or less rain/snow in winter and early spring, and low temperature or excess rainfall in summer, are inconducive to P. davidiana growth and vice versa …

Mental Model-Based Repeated Multifaceted (Mrm) Intervention Design: A Conceptual Framework For Improving Preventive Health Behaviors And Outcomes, Mazbahul G. Ahamad, Fahian Tanin

Department of Agronomy and Horticulture: Faculty Publications

Objective: Field interventions employed to improve preventive health behaviors and outcomes generally use well established approaches; however, recent studies have reported that health education and promotional interventions have little to no impact on health behaviors, especially in low- and middle-income countries. We aimed to develop a conceptual framework to improve intervention designs that would internalize these concerns and limitations.

Results: We identified three major experimental design- and implementation-related concerns associated with mental models, including the balance between the treatment and control groups, the treatment group’s willingness to adopt suggested behaviors, and the type, length, frequency, intensity, and sequence of treatments. …

Lymphocyte Proteomics For Monitoring Long Term Immune System Dynamics, Michaela Mccown

Undergraduate Honors Theses

Time dependent change in lymphocytes provides a necessary background for monitoring the development of Chronic Lymphocytic Leukemia from asymptomatic to malignant. Several bulk proteomics studies characterize differences between tumor cells and healthy B cells, yet the transition to symptomatic disease is not well understood. This could be shown by a longitudinal study beginning with asymptomatic patients if the rare tumor cells in early stages can be isolated from small volume blood draws and effectively characterized with few cells, such as was done here using healthy B cells to provide a baseline for such studies to discriminate routine fluctuation from pathogenic …

Dynamic Interplay Between The Co-Opted Fis1 Mitochondrial Fission Protein And Membrane Contact Site Proteins In Supporting Tombusvirus Replication, Wenwu Lin, Zhike Feng, K. Reddisiva Prasanth, Yuyan Liu, Peter D. Nagy

Plant Pathology Faculty Publications

Plus-stranded RNA viruses have limited coding capacity and have to co-opt numerous pro-viral host factors to support their replication. Many of the co-opted host factors support the biogenesis of the viral replication compartments and the formation of viral replicase complexes on subverted subcellular membrane surfaces. Tomato bushy stunt virus (TBSV) exploits peroxisomal membranes, whereas the closely-related carnation Italian ringspot virus (CIRV) hijacks the outer membranes of mitochondria. How these organellar membranes can be recruited into pro-viral roles is not completely understood. Here, we show that the highly conserved Fis1 mitochondrial fission protein is co-opted by both TBSV and CIRV via …

Grass Bud Responses To Fire In A Semiarid Savanna System, Quinn A. Hiers, Morgan L. Treadwell, Matthew B. Dickinson, Kathleen L. Kavanagh, Alexandra G. Lodge, Heath D. Starns, Doug R. Tolleson, Dirac Twidwell, Carissa L. Wonkka, William E. Rogers

Department of Agronomy and Horticulture: Faculty Publications

Increasingly, land managers have attempted to use extreme prescribed fire as a method to address woody plant encroachment in savanna ecosystems. The effect that these fires have on herbaceous vegetation is poorly understood. We experimentally examined immediate (<24 hr) bud response of two dominant graminoids, a C₃ caespitose grass, Nassella leucotricha, and a C₄ stoloniferous grass, Hilaria belangeri, following fires of varying energy (J/m² ) in a semiarid savanna in the Edwards Plateau ecoregion of Texas. Treatments included high- and low-energy fires determined by contrasting fuel loading and a no burn (control) treatment. Belowground axillary buds were counted and their activities classified to determine immediate effects …
