Poultry Litter Ash Reduces Phosphorus Losses During Greenhouse Production Of Lantana Camara L. ‘New Gold’, Daniel E. Wells, Jeffrey S. Beasley, Lewis A. Gaston, Edward W. Bush, Maureen E. Thiessen

Faculty Publications

Phosphorus (P) fertilizers with high water-solubility are often applied in excessive amounts to porous horticultural substrates to produce high-quality plants. As a result, high P losses during containerized plant production have presented an environmental challenge to responsible growers. Poultry litter ash (PLA), a byproduct of bioenergy production, contains P concentrations comparable to conventional P fertilizers but is characterized as having lower water-solubility. Therefore, a series of experiments were conducted to characterize effects of PLA on container-plant growth and P leaching. PLA was compared with superphosphate (SP), a highly water-soluble P source, in ratios of 0:100, 25:75, 50:50, 75:25, and 100:0 …

Effects Of Root Isoflavonoids And Hairy Root Transformation On The Soybean Rhizosphere Bacterial Community Structure, Laura White

Electronic Theses and Dissertations

Rhizodeposits play a key role in shaping rhizosphere microbial communities. In soybean, isoflavonoids are a key rhizodeposit component that aid in plant defense and enable symbiotic associations with rhizobia. However, it is uncertain if and how they influence rhizosphere microbial communities. Isoflavonoid biosynthesis was silenced via RNA interference of isoflavone synthase in soybean hairy root composite plants. Successive sonication was implemented to isolate soil fractions from 3 different rhizosphere zones at 1 and 3 weeks post planting. PCR amplicons from 16S rRNA gene variable regions V1- V3 and V3-V5 from these soil fractions were analyzed via denaturing gradient gel electrophoresis …

Local And Systemic Actions Of Gnrh Relating To Estradiol And Associated Reproductive Parameters In Beef Cattle, Jerica J.J. Rich

Electronic Theses and Dissertations

In cattle, estradiol is responsible for modulating many mechanisms involved in successful reproduction. Specifically estradiol is the primary signal for the initiation of standing estrus (Allrich, 1994), and cattle expressing estrus prior to fixed time AI (FTAI) have been reported to have increased preovulatory estradiol concentrations (Perry and Perry, 2008) and increased pregnancy success compared to animals that did not exhibit estrus (Richardson et al., 2016). Gonadotropin releasing hormone, classically, stimulates estradiol production via the two-cell two-gonadotropin hypothesis (Fortune and Quirk, 1988), and GnRH administered systemically in small doses (5 μg) has been reported to elicit an LH pulse similar …

Differential Gene Expression In Two Nodule Zones Of Soybean, Sunita Pathak Jan 2017

Differential Gene Expression In Two Nodule Zones Of Soybean, Sunita Pathak

Electronic Theses and Dissertations

Soybean, a leguminous plant and rhizobia establishes symbiotic relationships, forming root nodules. Nodule organogenesis starts with cortical cell division forming infection and parenchyma zones which houses N-fixing bacteria and block O2 for nitrogenase enzyme function, respectively. The mechanism by which root cortical cells give rise to two structurally and functionally different nodule tissues is not known. One approach to address this knowledge gap is to evaluate global gene expression patterns in these two tissue types during nodule development. Using INTACT method, we developed two promoters, ENOD2 (nodule parenchyma) and ENOD40 (infection zone) driven nuclear envelope biotin tagging constructs and isolated …

Lysine Bioavailability Of Two Lipid Coated Lysine Products After Exposure To Silages With Different Acidity, Jessica N. Reiners Jan 2017

Lysine Bioavailability Of Two Lipid Coated Lysine Products After Exposure To Silages With Different Acidity, Jessica N. Reiners

Electronic Theses and Dissertations

Three experiments were conducted to determine bioavailability of 2 lipid coated Lys products (EB and EC). In an initial experiment, Lys disassociation from 2 lipid coated Lys products was best described by a first-order kinetic model after incubation in alfalfa- or corn-silage at 2 different amounts of acidity. Greater amounts of Lys immediately disassociated from EC (15.7%) than EB (4.9%; P < 0.05). Lysine that initially disassociated in corn silage at low pH (0.5%) was less than corn silage at a more neutral pH (18.7%), whereas Lys that initially disassociated in alfalfa silage was not affected (P = 0.26) by pH. Lysine that slowly disassociated from lipid coated Lys differed by product (P = 0.01), and acidity (P < 0.01) affected amounts of Lys that slowly disassociated differently within alfalfa- or corn-silage (pH × silage = 0.02). Greater amounts of Lys disassociated from acidic corn silage (79%) than neutral corn silage (32%; P = 0.01). However, amounts of Lys that slowly disassociated from alfalfa silage was not impacted by acidity (P = 0.40). Additionally, amounts of Lys that did not disassociate (P < 0.04) within 24 h were greater (P < 0.04) when lipid coated Lys was mixed with neutral silages (44%) compared to acidic silages (21%). However, rate of Lys disassociation from lipid coated Lys products was not affected by acidity or exposure to alfalfa- or corn-silage (P = 0.21). In a second experiment, we measured in vitro ammonia release from EB and EC after mixing with alfalfa- or corn-silage at different amounts of acidity with or without monensin. Ammonia release from Lys increased (Quadratic < 0.01) with greater amounts of time; however, differences between in vitro cultures with added Lys and negative control were not detected until 36 h of incubation. By 36 h, all cultures containing added Lys were greater than the negative control. After 42 h of incubation, ammonia release from Lys was greatest from EC and when lipid and Lys-HCl in amounts identical to EB were provided to cultures; EB, Lys-HCl, and lipid and Lys in amounts identical to EC were intermediate. After 48 h of incubation, ammonia release from Lys in EB was greatest and Lys-HCl was least, but EC and amounts of lipid and Lys-HCl identical to either EB or EC were intermediate. Ammonia release from Lys were less from cultures containing monensin after 48 h of incubation. In experiment 3, 9 white-faced ewes (70.1 ± 5.2 kg BW; 5.3 ± 0.6 yr) were used to measure Lys bioavailability by a slope-ratio analysis from 2 lipid coated Lys products and Lys-HCl after mixing in corn silage. Plasma Lys concentrations increased (Linear < 0.01) in response to abomasal infusion of Lys, and bioavailability of EB, EC, and Lys- HCl were calculated to be 10.74%, 18.82%, and 11.87%, respectively. However, increases in plasma Lys from EB (Linear = 0.41) and Lys-HCl (Linear = 0.36) were not different from plasma Lys supported by diet alone, but the rate of increase in plasma Lys in response to EC tended (Linear = 0.15) to be greater than plasma Lys levels from diet. Evidently, manufacturing method among lipid coated Lys products as well as physical and chemical characteristics of diet can impact availability of Lys from lipid coated Lys products.

Silencing Seed Dormancy Genes To Mitigate Risk Of Transgene Flow To Weedy Rice, Alexander Wireko Kena Jan 2017

Silencing Seed Dormancy Genes To Mitigate Risk Of Transgene Flow To Weedy Rice, Alexander Wireko Kena

Electronic Theses and Dissertations

The flow of fitness-enhancing transgenes from genetically modified crops into wild/weed relatives may cause serious ecological and economic consequences. Seed dormancy (SD) is a key adaptive trait that distributes germination over time, resulting in weed persistence in agroecosystems. Thus, silencing major genes controlling SD would reduce the adaptive fitness of weeds. SD-enhancing genes cloned from weedy rice include SD7-1, SD7-2, SD12a, SD12b, and SD12c. The goal of this study was to develop a transgenic mitigation (TM) strategy using SD gene-silencing structures as mitigating factors to reduce the risk of transgene flow to wild/weed populations.
