Overcoming India’S Food Security Challenges: The Role Of Intellectual Property Management And Technology Transfer Capacity Building, Stanley Kowalski, Aarushi Gupta, Ifica Mehra
Law Faculty Scholarship
The growth of the Indian economy after Independence has had little impact on the food security of the country. The paper analyses the development of advanced crop varieties through the use of agricultural technologies (hereinafter "agbiotech") within the technology transfer system, a framework which comprises of the interactions of intellectual property rights law and agricultural research and development in India. Through this, the author argues that agricultural innovation in India is failing due to the absence of connections within the technology transfer system and advocates for the creation of a national program aimed at advancing IP and tech-transfer capacity in …

Growth Of Bella Bluegrass Compared To A Standard Kbg Blend And Tall Fescue, Paul Johnson, Xin Dai, Roberrto Gurel
Growth Of Bella Bluegrass Compared To A Standard Kbg Blend And Tall Fescue, Paul Johnson, Xin Dai, Roberrto Gurel
CWEL Publications
A goal of low-input turfgrass is to reduce mowing, thereby reducing labor, fuel, and equipment expenses. A way to meet this goal is to develop grasses that grow slower. 'Bella' Kentucky bluegrass was released by the University of Nebraska-Lincoln as a slow-growing variety of bluegrass. This experiment documents slightly to significantly slower growth of 'Bella' compared to a traditional Kentucky bluegrass sod blend and tall fescue grown in the Intermountain West region of North America. Consumers frequently seek grasses that need less mowing and fertilizer (Busey and Parker, 1992). Although turfgrasses recover from traffic by growing, many uses don't need …

Center for Plant Science Innovation: Faculty Publications
Iron is an important micronutrient in human and plant nutrition. Adequate iron nutrition during crop production is central for assuring appropriate iron concentrations in the harvestable organs, for human food or animal feed. The whole-plant movement of iron involves several processes, including the reduction of ferric to ferrous iron at several locations throughout the plant, prior to transmembrane trafficking of ferrous iron. In this study, soybean plants that constitutively expressed the AtFRO2 iron reductase gene were analyzed for leaf iron reductase activity, as well as the effect of this transgene's expression on root, leaf, pod wall, and seed mineral concentrations. …

West Central Research and Extension Center, North Platte
Understanding the biology of heifer maturity and its relationship to calving difficulty and subsequent breeding success is a vital step in building a bioeconomic model to identify optimal production and profitability. A limited dependent variable probit model is used to quantify the responses among heifer maturities, measured by a maturity index (MI), on dystocia and second pregnancy. The MI account for heifer age, birth BW, prebreeding BW, nutrition level, and dam size and age and is found to be inversely related to dystocia occurrence. On average there is a 2.2% increase in the probability of dystocia with every 1 point …

Department of Agronomy and Horticulture: Faculty Publications
Triacylglycerol (TAG) metabolism is a key aspect of intracellular lipid homeostasis in yeast and mammals, but its role in vegetative tissues of plants remains poorly defined. We previously reported that PHOSPHOLIPID:DIACYLGLYCEROL ACYLTRANSFERASE1 (PDAT1) is crucial for diverting fatty acids (FAs) from membrane lipid synthesis to TAG and thereby protecting against FA-induced cell death in leaves. Here, we show that overexpression of PDAT1 enhances the turnover of FAs in leaf lipids. Using the trigalactosyldiacylglycerol1-1 (tgd1-1) mutant, which displays substantially enhanced PDAT1- mediated TAG synthesis, we demonstrate that disruption of SUGAR-DEPENDENT1 (SDP1) TAG lipase or PEROXISOMAL TRANSPORTER1 (PXA1) severely decreases …

The Middle Eocene Climatic Optimum (MECO; ~ 40 million years ago [Ma]) is one of the most prominent transient global warming events in the Paleogene. Although the event is well documented in geochemical and isotopic proxy records at many locations, the marine biotic response to the MECO remains poorly constrained. We present new high-resolution, quantitative records of siliceous microplankton assemblages from the MECO interval of Ocean Drilling Program (ODP) Site 1051 in the subtropical western North Atlantic Ocean, which are interpreted in the context of published foraminiferal and bulk carbonate stable isotope (δ18O and δ13C) records. …

Reduced Inputs Turfgrass Through White Clover Inclusion, Bret Andrew Sparks
Reduced Inputs Turfgrass Through White Clover Inclusion, Bret Andrew Sparks
Theses and Dissertations--Plant and Soil Sciences
Most managed turfgrass species require frequent inputs to maintain an acceptable level of quality. Among these inputs, nitrogen (N) fertilization is usually the most limiting in terms of growth and development. However, N fertilization is also linked to non-point source (NPS) pollution. White clover (WC) is known for its ability to provide N when mixed into stands of turfgrass, and does not pose a threat for NPS pollution. Two field studies were designed to investigate the effects of WC inclusion in stands of cool-season turfgrasses. In the first field study, three cultivation techniques were examined for establishment of WC into …

Boron Nutrition Of Burley And Dark Tobacco, Laura Ann Frakes Mitchell
Theses and Dissertations--Plant and Soil Sciences
The incidences of suspected Boron (B) deficiency have increased recently in Kentucky tobacco fields, potentially due to recent changes in management practices. The symptoms observed in the field include; hollow stalk, stunted growth, deformed or no bud formation, small slits on the lower leaf midrib and uncontrollable breaking of the midrib approximately two inches from the stalk. B is a micronutrient tobacco needs in minute amounts, however excessive additions of B could cause toxicity. The objectives of this work were to 1) establish critical points for B sufficiency, 2) describe and define B deficiency and toxicity symptoms and 3) develop …

Saudi Arabian Students In Detroit Use Natural Health Products More So Than Other University Students In Detroit, Samiah Naji Alqahtani
Wayne State University Theses
Natural Health Products (NHP), are defined as products that derive from organisms and may include supplements and herbal/traditional remedies. Prior research indicates that females use NHP more than males. We have unpublished data to show that students use NHP for health maintenance with significantly different use of NHP by Native/Aboriginal students vs. other students. Less is known about Saudi students. We hypothesize that: (1) There are gender differences in NHP used; and (2) There are geo-ethnic differences in NHP used. We also determine the predictor variables that influence NHP use by students. Students from Wayne State University (n=560; 193 …

Potassium Fertilization Mitigates The Adverse Effects Of Drought On Selected Zea Mays Cultivars, Lixin Zhang, Mei Gao, Shengxiu Li, Ashok Kumar Alva, Muhammad Ashraf
Turkish Journal of Botany
In the present study, the role of potassium (K) in mitigating the adverse effects of drought stress (DS) on 2 maize (Zea mays L.) cultivars, 'Shaandan 9' (S_{9}; drought-tolerant) and 'Shaandan 911' (S_{911}; drought-sensitive), was assessed. K application increased dry matter (DM) across all growth stages and grain yield (GY) in both cultivars under DS, but not under control conditions. Drought-tolerant cultivar S_9 was superior to drought-sensitive cultivar S_{911} under DS in terms of DM and GY regardless of K addition. Additionally, K application increased relative water content, nitrate reductase activity, and concentrations of potassium ion, free proline, soluble protein, …

Tomato Fruit Quality As Influenced By Salinity And Nitric Oxide, Hala Ezzat Mohamed Ali, Ghada Saber Mohamed Ismail
Turkish Journal of Botany
The impact of salinity (measured by adding 100 mM of NaCl to the nutrient solution) and spraying with sodium nitroprusside (10 µM of SNP, NO source) on fruit quality of tomato (Super Strain B) plants grown under field conditions was studied. Irrigation with salinised nutrient solution alone resulted in a significant suppression in fruit fresh and dry biomass, length, diameter, and volume as well as \beta-carotene and lycopene contents. This decrease was accompanied by a significant increase in Na accumulation, total alkaloids, and antioxidants, including total phenolics and flavonoids, and reduced ascorbic acid (ASA) content. Similar to total phenolics and …

Does Gypsum Influence Seed Germination?, Eva M. Cañadas, Miguel Ballesteros, Francisco Valle, Juan Lorite
Turkish Journal of Botany
Flora inhabiting gypsum outcrops in arid environments shows a high level of specialization. However, the processes involved are still unclear, specifically at the key stage of germination. Here, to assess whether gypsum could chemically influence seed germination, we tested the germination of species according to 3 functional groups: gypsophiles, gypsovags, and calcicoles. A total of 24 taxa were selected, all occurring in gypsum and limestone substrates, under a semiarid and dry Mediterranean climate. Three levels of gypsum (CaSO_{4}^.2H_{2}O) solution (low = 0.5 g/L, medium = 1 g/L, and high = 2.4 g/L) and 1 control treatment of distilled water were …

Study On Seed Morphometry Of Some Threatened Western Himalayan Orchids, Jagdeep Verma, Kusum Sharma, Kranti Thakur, Jaspreet Kaur Sembi, Suraj Prakash Vij
Turkish Journal of Botany
Physical seed characteristics of 32 threatened Western Himalayan orchids belonging to 23 genera of 3 subfamilies were studied using light and scanning electron microscopy. The species showed remarkable seed shape variations (fusiform, spathulate, ovoid, filiform) irrespective of their taxonomic position. Epiphytes produced relatively small-sized seeds compared to their terrestrial, lithophytic, or mycoheterotrophic counterparts. Seeds were truncated (length/width < 6.0) in 27 species, and were mostly elongated (length/width = 19.957 ± 1.459) in the orchidoid species Goodyera biflora (Lindl.) Hook.f. The number or size of testa cells was found fairly consistent at the genus level, and their walls were straight, sinuous, or undulate. Periclinal walls possessed vertical or oblique ornamentation in 6 species, which is of taxonomic implication. Embryos were rather tiny and most of the seed space (even >90% in 7 species) was occupied by air. The highest seed to embryo volume ratio was recorded in terrestrial Liparis odorata (Willd.) Lindl. and the lowest in epiphytic Rhynchostylis retusa (L.) Blume, both of which are members of the advanced Epidendroideae. Seed characteristics …

Plasticity And Within Plant Sex-Ratio Variation In Monoecious Emex Spinosa, Regina Berjano, Montserrat Arista, María Talavera, María Jesús Ariza, Pedro Luis Ortiz
Turkish Journal of Botany
Understanding how phenotype trait expression varies at different levels of biological organization is crucial to understanding the fundamental ecological, evolutionary, and developmental issues that contribute to adaptive plasticity. This is particularly important in plants because of their modular organization. Here, we study plasticity in flower production in response to light intensity at 3 levels of biological organization (between populations, among individuals, and within individuals) in Emex spinosa (L.) Compd., a Mediterranean amphicarpic annual. Plants exposed to high light intensity grew faster and produced more flowers than plants at low light intensity. Female flower production was the most labile trait. Within …

Turkish Journal of Botany
To identify and isolate genes related to abiotic stress (salinity and drought) tolerance in grapevine, a candidate gene approach led to the isolation from Cabernet Sauvignon cultivar of a full-length cDNA of dehydrin gene. The latter, named VvDhn, which is highly and mainly induced in late embryogenesis in seeds, encodes for a protein of 124 amino acids with a predicted molecular mass of 13.3 kDa. Details of the physicochemical parameters and structural properties (molecular mass, secondary structure, conserved domains and motives, and putative posttranslational modification sites) of the encoded protein have also been elucidated. The expression study of VvDhn was …

Department of Plant Pathology: Faculty Publications
Sorghum lines were bred for reduced lignin for cellulosic bioenergy uses, through the incorporation of brown midrib (bmr)6 or -12 into two backgrounds (RTx430 and Wheatland) as either single or doublemutant lines. When these lines were assessed for resistance to Fusarium thapsinum stalk rot, a cause of lodging, they were as resistant to F. thapsinum as the near-isogenic wild type. Peduncles of newly identified bmr lines from an ethyl-methanesulfonate-mutagenized population, inoculated with F. thapsinum, were as resistant as the wild-type line, BTx623. One bmr line (1107) had significantly smaller mean lesion lengths than BTx623, suggesting that a mutation …

College Students’ Perceptions Regarding Sensory Aspects Of Conventionally Produced And Unconventionally Produced Foods: Implications For Marketing To The Millennial Generation, Christina Crowder, Catherine W. Shoulders, K. Jill Rucker
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Consumers vote every day on which products line the shelves of grocery stores, co-ops, and niche markets. Public unrest with regard to the environmental, animal welfare, food purity, and human health impacts of agricultural production practices have led to the rise of unconventionally produced (UP) food products. While the sales of UP foods is increasing, studies regarding the qualities of such products that impact consumer purchases have yielded inconsistent results. This study examined students’ perceptions of sensory aspects of conventionally produced (CP) and UP foods to better understand how sensory aspects impact decisions to purchase. Students reported consistent perceptions regarding …
Effects Of Asphondylia Borrichiae, Simulated Herbivory, And Nutritional Status On Survival, Flowering, And Seed Viability In Sea Oxeye Daisy (Borrichia Frutescens), Lisa S. Rowan
UNF Graduate Theses and Dissertations
Although herbivory and other types of plant damage typically are viewed as detrimental to plant survival and performance, vigorous regrowth, greater seed set, and fitness benefits may be possible when damage to the apical meristem, or actively growing stem terminal, is involved. Such damage releases apical dominance, or the hormonal suppression of lateral buds, activates dormant lateral buds, and enables lateral shoots to grow. Since in plants with terminal flowers, each stem may bear a flower, removal of the apical meristem may result in stem bifurcation and ultimately increase the number of flowers and seeds, thereby increasing potential fitness. In …
