Cocoa has been useful in several ways, especially to countries that produce it and consumers all over the world. Its benefits range from improving economies to satisfying millions all over the world who desire one cocoa product or the other. The production of cocoa however is not without its own attendant problems. Aging tree stock, spread of diseases, and production capacity problems are, but a few of many challenges that seed gardens that produce cocoa face. This study investigated the pollination process on selected seed gardens in Ghana, the second largest world producer of cocoa. The purpose of this study ...
The Development Of Polyamines Throughout Brassica Rapa Over Its Lifecycle, 2014 University of New Hampshire
The Development Of Polyamines Throughout Brassica Rapa Over Its Lifecycle, Matthew Ryan Sullivan, Jon Larsen, Subhash C. Minocha
Student Research Projects
Polyamines are naturally produced chemicals in plants involved in growth, development and stress response. The primary objective of my study is to create a profile of changes in the entire life of the plant, in every organ at all stages of development from seed germination to seed formation. We have analyzed polyamines putrescine, spermidine and spermine in all parts of Brassica rapa, a small, rapid growing plant. Parallel to the polyamines, we will also study changes in the activities of the polyamine biosynthetic enzymes and the expression of their genes in different organs at different times. In the next stage ...

Entomology Publications and Papers
The fall armyworm, Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), is an important pest of maize in the United States and many tropical areas in the western hemisphere. In 2001, Herculex I® (Cry1F) maize was commercially planted in the United States to control Lepidoptera, including S. frugiperda. In 2006, a population of S. frugiperda was discovered in Puerto Rico that had evolved resistance to Cry1F maize in the field, making it the first well-documented case of an insect with field resistance to a plant producing protein from Bacillus thuringiensis (Bt). Using this resistant population, we conducted tri-trophic studies with a ...
Reassessment Of Practical Subspecies Identifications Of The Usda Daucus Carota L. Germplasm Collection: Morphological Data, David M. Spooner, Mark P. Widrlechner, Kathleen R. Reitsma, Debra E. Palmquist, Slim Rouz, Zeineb Ghrabi-Gammar, Mohamed Neffati, Béchir Bouzbida, Philipp W. Simon, Mohammed El Koudrim
NCRPIS Publications and Papers
The genus Daucus includes about 20 recognized species. The most widespread and economically important species, Daucus carota L., occurs on almost every continent. The cultivated carrot, subsp. sativus (Hoffm.) Schübl. and G. Martens, has been selected from wild populations that are extremely diverse, especially in the western Mediterranean. The predominant outcrossing and the lack of sexual isolating mechanisms among recognized infraspecific taxa complicate the taxonomy and identification of the wild populations, resulting in widely different interpretations of the number of infraspecific taxa. We measured 36 morphological characters from multiple individuals within each of 155 accessions of D. carota and from ...
Registration Of ‘Mattern’ Waxy (Amylose-Free) Winter Wheat, 2014 University of Nebraska, Lincoln
Registration Of ‘Mattern’ Waxy (Amylose-Free) Winter Wheat, P S. Baenziger, R A. Graybosch, D K. Santra, T Regassa, Y Jin, S Wegulo, G Bai, P S. Amand, X Chen, B Seabourn, F Dowell, R Bowden, D M. Marshall
Teshome H. Regassa
‘Mattern’ (Reg. No. CV-1092, PI 665947) hard winter waxy wheat (Triticum aestivum L.) was developed cooperatively by the USDA–ARS and the Nebraska Agricultural Experiment Station and released in 2012. Mattern has red grain color and waxy (amylose-free) endosperm starch. It was released primarily for its unique end-use quality attributes and for grain yield competitive with currently grown Nebraskaadapted cultivars. The waxy starch is conditioned by the presence of three naturally occurring mutations that eliminate production of the enzyme granule-bound starch synthase. Granule-bound starch synthase synthesizes amylose in typical wheats and other cereal crops. Mattern was tested experimentally as NX04Y2107 ...
Using Resistant Prey Demonstrates That Bt Plants Producing Cry1ac, Cry2ab, And Cry1f Have No Negative Effects On Geocoris Punctipes And Orius Insidiosus, Jun-Ce Tian, Li-Ping Long, Xiang-Ping Wang, Steven E. Naranjo, Jörg Romeis, Richard L. Hellmich, Ping Wang, Anthony M. Shelton
Entomology Publications and Papers
Geocoris punctipes (Say) and Orius insidiosus (Say) are generalist predators found in a wide range of crops, including cotton (Gossypium hirsutum L. ) and maize (Zea mays L. ), where they provide important biological control services by feeding on an array of pests, including eggs and small larvae of caterpillars. A high percentage of cotton and maize in the United States and several other countries are transgenic cultivars that produce one or more of the insecticidal Cry proteins ofBacillus thuringiensis Berliner (Bt). Here we quantify effects of three Cry proteins on the life history of these predators over two generations when ...

Theses, Dissertations, and Other Capstone Projects
Arctotheca prostrata is a perennial plant species native to South Africa that reproduces vegetatively by long runners. In South Africa it also reproduces sexually, producing fruits with fertile seeds. The species was brought to California to serve as a ground cover but fruits had not been reported. Historically, it has been said to be infertile. This study tested the fertility of A. prostrata in California by crossing plants from California with each other and with plants grown from imported South African seeds. Pollen viability was tested and morphological measures were made on heads, leaves, and pollen. Mean Californian and South ...
Fusarium Head Blight Resistance And Agronomic Performance In Soft Red Winter Wheat Populations, 2014 University of Kentucky
Fusarium Head Blight Resistance And Agronomic Performance In Soft Red Winter Wheat Populations, Daniela Sarti Dvorjak
Theses and Dissertations--Plant and Soil Sciences
Fusarium head blight (FHB), caused by Fusarium graminearum Schwabe [telomorph: Gibberella zeae Schwein.(Petch)], is recognized as one of the most destructive diseases of wheat (Triticum aestivum L. and T. durum L.) and barley (Hordeum vulgare L.) worldwide. Breeding for FHB resistance must be accompanied by selection for desirable agronomic traits. Donor parents with two FHB resistance quantitative trait loci (QTL) Fhb1 (chromosome 3BS) and QFhs.nau-2DL (chromosome 2DL) were crossed to four adapted SRW wheat lines to generate backcross and forward cross progeny. F2 individuals were genotyped and assigned to 4 different groups according to presence/ absence of ...
The Performance Of Bacterial Phytosensing Transgenic Tobacco Under Field Conditions, 2013 University of Tennessee, Knoxville
The Performance Of Bacterial Phytosensing Transgenic Tobacco Under Field Conditions, Michael Harrison Fethe
Currently the platforms for wide-area detection of environmental contamination are limited. Therefore, there is interest in developing new platforms, especially for use in crop plants to detect and report the presence of biotic and abiotic stress agents. A biosensor uses a biological organism or substrate to detect the presence of an elicitor (i.e., heavy metal, TNT, or bacteria). The foundational groundwork to create biosensors in transgenic plants exists. The creation of bacterial phytosensing transgenic tobacco containing an orange fluorescent protein (OFP) reporter driven by synthetic pathogen-inducible promoters provides a fluorescent signal when infected with phytopathogens for earlier detection in ...

Identifying Molecular Markers Associated With Salt And Boron Tolerance In Poplar Trees, 2013 California Polytechnic State University
Identifying Molecular Markers Associated With Salt And Boron Tolerance In Poplar Trees, Darshanpreet Gill, Nathan Follen, Davis W. Cheng, Kyan Salehi, Gary Banuelos, James P. Prince
STEM Teacher and Researcher (STAR) Program Posters
Standard irrigation practices promote salt and boron accumulation in soils on the Westside of Central California. The build-up of these inorganic salts leads to the degradation of arable land and reduction of crop production. Different clones of poplar trees have been shown to grow in salt- and boron-contaminated soils, and in doing so, gradually remove significant amounts of these inorganic salts from the soil. In an effort to identify molecular markers linked with salt and boron tolerance in poplars, 31 PCR primer pairs have been designed based on candidate genes identified from the literature, and an additional 31 PCR primer ...
Bioconfinement Of A Putatively Sterile Nicotiana Hybrid And Development Of Tools For Assessing Gene Flow, 2013 University of Tennessee, Knoxville
Bioconfinement Of A Putatively Sterile Nicotiana Hybrid And Development Of Tools For Assessing Gene Flow, John Hollis Rice
Production of transgenic crops in open field environments is an ongoing concern of due to the potential for gene flow. New transgenic crops, such as plant-made-pharmaceuticals may generate additional concerns about effects of adventitious transgenes. Use of a bioconfinement strategy may alleviate any consequences by preventing gene flow. The following chapters discuss previous and current research on gene flow, testing of a Nicotiana hybrid system for bioconfinement efficiency, and development of methods for transgene detection. The candidate ‘platform plant’ that was tested is a Nicotiana hybrid (Nicotiana tabacum ‘TN 90’ × Nicotiana glauca) previously identified to be sexually sterile. To quantify ...
Identification Of Cyclophilin Gene Family In Soybean And Characterization Of Gmcyp1, 2013 Western University
Identification Of Cyclophilin Gene Family In Soybean And Characterization Of Gmcyp1, Hemanta Raj Mainali
University of Western Ontario - Electronic Thesis and Dissertation Repository
I identified members of the Cyclophilin (CYP) gene family in soybean (Glycine max) and characterized the GmCYP1, one of the members of soybean CYP. CYPs belong to the immunophilin superfamily with peptidyl-prolyl cis-trans isomerase (PPIase) activity. PPIase catalyzes the interconversion of the cis- and trans-rotamers of the peptidyl-prolyl amide bond of peptides. After extensive data mining, I identified 62 different CYP genes in soybean (GmCYP1 to GmCYP62), of which 8 are multi-domain proteins and 54 are single domain proteins. At least 25% of the GmCYP genes are expressed in soybean. GmCYP1 localizes to the nucleus and the cytoplasm and ...

Biological Sciences Faculty Research Publications
In an effort to identify newly evolved genes in rice,we searched the genomes of Asian-cultivated rice Oryza sativa ssp. japonica and its wild progenitors, looking for lineage-specific genes. Using genome pairwise comparison of approximately 20-Mb DNA sequences from the chromosome 3 short arm (Chr3s) in six rice species, O. sativa, O. nivara, O. rufipogon, O. glaberrima, O. barthii, and O. punctata, combined with synonymous substitution rate tests and other evidence, we were able to identify potential recently duplicated genes, which evolved within the last 1 Myr. We identified 28 functional O. sativa genes, which likely originated after O. sativa ...
Alternative Poa Species As Permanent And Temporary Turfgrasses In The Transition Zone, 2013 University of Tennessee, Knoxville
Alternative Poa Species As Permanent And Temporary Turfgrasses In The Transition Zone, Samuel Lucas Freshour
As restrictions on water, fertilizer, and pesticide use increase, along with public pressure, turfgrass practitioners will need ways to meet the challenges of reduced inputs while still maintaining acceptable turf quality. Proper selection of turfgrass species and cultivars that are adapted to the climate, intended use, and level of expectation is the best and first line of defense for reduced input situations. The objective of this study was to evaluate alternative species from the bluegrass (Poa) genus for their performance as both permanent and temporary winter turfgrass species. In 2010 and 2011, 45 different treatments consisting of 37 different bluegrasses ...
Effects Of Leaflet Orientation And Root Morphology On Physiological Traits And Yield In Soybeans., 2013 University of Tennessee, Knoxville
Effects Of Leaflet Orientation And Root Morphology On Physiological Traits And Yield In Soybeans., Richard Dewayne Johnson
Drought is the most important abiotic stress adversely affecting soybean (Glycine max (L.) Merr.) yield. Leaflet orientation has been shown to reduce leaflet temperatures and transpiration while root morphology has been related to slower wilting phenotypes. The objective of this study was to investigate effects of leaflet orientation and rooting morphology on whole plant transpiration, yield, water use efficiency, and other physiological traits in soybeans using grafting techniques, population lines, near-isogenic lines, and restrained leaf canopy experiments. Experiments were conducted in Knoxville, TN with additional yield trial plots at Springfield, Spring Hill, and Milan, TN. Data were collected on whole ...
