Arabidopsis Tt8 Orthologue Of Pinto Bean (Phaseolus Vulgaris L.) Regulates Proanthocyanidin Genes And Seed Coat Darkening, Nishat Shayala Islam
Arabidopsis Tt8 Orthologue Of Pinto Bean (Phaseolus Vulgaris L.) Regulates Proanthocyanidin Genes And Seed Coat Darkening, Nishat Shayala Islam
Electronic Thesis and Dissertation Repository
Postharvest darkening of seed coat in pinto bean (Phaseolus vulgaris L.) is an undesirable trait that hinders its market potential. Darkening is more rapid in the cultivars like CDC Pintium than the newly developed slow darkening cultivar 1533-15. A single gene, SLOW DARKENING (Sd), is responsible for the slow darkening in pinto beans and the trait co-segregates with two simple sequence repeat (SSR) markers. The objective of this research is to identify and characterize the Sd gene to understand the slow darkening mechanism in pinto bean seed coat. A search for Sd within the linkage distance from …
Confirming World-Wide Distribution Of An Agriculturally Important Lacewing, Chrysoperla Zastrowi Sillemi, Using Songs, Morphology, Mitochondrial Gene Sequencing, And Phylogenetic Reconstruction, Zoe Mandese
Honors Scholar Theses
The Chrysoperla carnea-group of green lacewings is a cryptic species complex. Species within the group are morphologically similar, yet isolated from one another via reproductive mating song. Chrysoperla zastrowi, a species within the carnea-group, is currently described with a distribution ranging from South Africa to the Middle East and India. However, recent collections of carnea-group lacewings from Guatemala and California were preliminarily identified as Chrysoperla zastrowi based upon similarities in their vibrational courtship songs. This analysis aims to place six specimens, collected by collaborators in Guatemala, Armenia, Iran, and California, into a pre-existing phylogeny of the …
Grapevine Vein Clearing Virus: Epidemiological Patterns And Construction Of A Clone, Cory Von Keith
Grapevine Vein Clearing Virus: Epidemiological Patterns And Construction Of A Clone, Cory Von Keith
MSU Graduate Theses
Grapevine vein clearing virus (GVCV) is a recently discovered virus belonging to the Badnavirus genus. Characteristic to its name, the virus is associated with a disease where symptoms manifest as pronounced vein-clearing, resulting in severe berry deformation and vine decline in susceptible grape varieties. Sustainable production of wine is dependent on healthy plants. The associated disease is mainly found in Midwest vineyards. Attempts were made in this thesis to provide evidence of causality of the virus to the associated disease and to infer the historical path and migration pattern of GVCV. Conclusions and discussions will provide grape producers with the …
The Identification Of Interspecific Hybrids Between Jaeger 70 X Vignoles Grapes Using Ssr Markers, Carl William Knuckles Iv
The Identification Of Interspecific Hybrids Between Jaeger 70 X Vignoles Grapes Using Ssr Markers, Carl William Knuckles Iv
MSU Graduate Theses
Jaeger 70 cultivar is an interspecific hybrid of Vitis linececumii x Vitis rupestris, with an interesting past. It was created by Hermann Jaeger of Neosho, MO, who is most notable for saving the French wine industry by developing phylloxera resistant rootstocks in the mid-1800s. Traditionally the Jaeger 70 variety has been grafted to French wine grape cultivars to impart disease resistance and cold hardiness while retaining desirable wine characteristics. One interesting characteristic of Jaeger 70 is that it is a female-only plant, allowing for many interesting areas of study. Vitis interspecific hybrid Vignoles, is a cold hardy cultivar of largely …
Production Of A Candidate Recombinant Protein Vaccine For Mannheimia Haemolytica In Lettuce And Tobacco Chloroplasts, Coby K. Martin
Production Of A Candidate Recombinant Protein Vaccine For Mannheimia Haemolytica In Lettuce And Tobacco Chloroplasts, Coby K. Martin
Electronic Thesis and Dissertation Repository
The cattle industry worldwide is ravaged by bovine respiratory disease (BRD), a bacterial disease caused by Mannheimia haemolytica. Recent efforts to design vaccines against M. haemolytica focus on a virulence factor, leukotoxin, in addition to surface lipoproteins. Plant-based protein production is a safe and inexpensive alternative to traditional methods. Edible vaccines deliver antigens to pharyngeal tissues, which can provide local immunization against M. haemolytica prior to its progression into the lungs. In this project, a chimeric protein containing M. haemolytica antigens was produced in tobacco chloroplasts as a candidate edible vaccine for BRD. Attempts were made to transform lettuce …
Chemical Topping Burley Tobacco, Mitchell D. Richmond
Chemical Topping Burley Tobacco, Mitchell D. Richmond
Theses and Dissertations--Plant and Soil Sciences
The act of topping tobacco (Nicotiana tabacum L.) involves the removal of the terminal bud or inflorescence of the tobacco plant. This practice ordinarily is accomplished by manually removing the top of each tobacco plant in an entire field which is labor intensive and costly. Chemical topping utilizes sucker control products to inhibit the terminal bud and axillary bud growth without manually removing the top of the tobacco plant. There were several research objectives in order to determine the utility of a chemical topping system: 1) determine if burley tobacco could be chemically topped with currently registered suckercide products …
Adverse Pregnancy Outcomes And Imbalance In Angiogenic Growth Mediators And Oxidative Stress Biomarkers Is Associated With Advanced Maternal Age Births: A Prospective Cohort Study In Ghana, Enoch Odame Anto, William K.

Research outputs 2014 to 2021
Background Advanced maternal age (AMA) has been associated with negative pregnancy outcomes. Oxidative stress (OS) and defective placental dysfunction are contributing factors. This study determined the association between AMA and adverse pregnancy outcomes, OS biomarkers and angiogenic growth mediators (AGMs) in normal pregnancies. Methods This prospective cohort study conducted at the Obstetrics and Gynaecology (O&G) Department of the Komfo Anokye Teaching Hospital (KATH) finally included 175 normal pregnant women comprising, 58 AMA (35–45 years), 55 (30–34 years) and 62 optimal childbearing age (20–29 years). Venous blood samples were collected at 28–32 weeks for soluble fms-like tyrosine kinase-1 (sFlt-1), placental growth …
