Molecular approaches to improve soybean plant architecture and seed composition
… to improve the value of soybean, yield and seed composition deserve attention considering its ever-increasing demand as well as where its overall value comes from. In terms of yield improvement, the current research suggested an alternative strategy to remodel the architecture of soybean …

NESTED ASSOCIATION MAPPING TO IDENTIFY SEED COMPOSITION QTL IN DIVERSE SOYBEAN LINES
… and environmental factors controlling soybean seed composition is an essential prerequisite for such an endeavor. Three separate studies were initiated to understand the underlying genetics governing soybean seed compositional traits.

Exploiting natural variation in Plantago seed composition for food and human health applications
… a method for small-scale rapid fractionation of seed mucilage (Cowley et al. 2020, Plant Methods, 16:20). Most published seed mucilage extraction techniques while simple and robust, were recognised early in my candidature to be less than ideal for screening natural variants.. Previously published …

Molecular Analyses of the Soybean Glabrous Mutation (P1) and of Transgenic Lines Designed to Modify Seed Composition
… expression of the PDHK gene(s) in soybean seeds specifically by introduction of a PDHK RNAi construct transgenically into soybean. The insertion of the PDHK RNAi construct was confirmed in the soybean sublines by PCR and Southern blot analysis. The dry seeds from the transgenic lines were …

Integrating Genomic and Phenomic Breeding Selection Tools with Field Practices to Improve Seed Composition Quality Traits in Soybean
… identify sulfur fertilization impact on soybean seed composition including amino and fatty acid profiles. First, a genome-wide association study (GWAS) analyzed genomic influence on proteinogenic methionine in soybean seeds which identified 23 single nucleotide polymorphisms (SNPs). Utilizing a …

Evaluation and characterization of QTL controlling seed composition in soybean and breeding for resistance to sudden death syndrome of soybean
… up breeding work is performed on QTL controlling seed composition in soybean and QTL conferring resistance to sudden death syndrome of soybean. In chapter 2, a genetic locus conferring pink flowers, the wp locus, and a confirmed seed protein concentration QTL located on chromosome 20 are evaluated …

GENETIC ANALYSIS OF SELECTED SEED CONSTITUENT TRAITS IN CHICKPEA (Cicer arietinum L.)
Seed composition is a major factor that influences grain utilization and end-use. To improve chickpea (Cicer arietinum L.) seed quality, it is imperative to identify novel genetic resources with desired seed composition for use in breeding programs. The specific objectives of the study were: 1) to …

Characterization of Soybean Germplasm with Modified Phosphorus and Sugar Composition
… Merr.] cultivars with modified phosphorus (P) composition has nutritional and environmental benefits, but poor seed germination and emergence presents challenges for commercial production. Different genetic mutations in two sources of germplasm, CX1834 and V99-5089, decrease the phytate and …

Breeding for increased protein concentration, sudden death syndrome resistance, and soybean cyst nematode resistance in soybean
… value of soybean through genetic improvement of seed composition and disease resistance traits. In order for a gene to be effectively incorporated into a breeding program, it must maintain its desired effect across many genetic backgrounds without a negative effect on agronomic traits such as …

Enhancing Seed Quality and Application of Soybean through High Test Weigh and Low Trypsin Inhibitors
Soybean is an integral oilseed crop that is used all over the world. Despite this, soybean has been experiencing a decrease in seed quality seen by the decreasing trend in test weight, and is limited in its uses due to the antinutritional factor, trypsin inhibitor (TI). This project first worked to …

A Survey of the Agronomic and End Use Characteristics of Low Phytic Acid Soybeans
… 75% of the P in soybean (Glycine max L. Merr.) seeds, but it is indigestible by mono- and agastric animals resulting in economic and environmental detriment. Soybean lines with genetically reduced PA contents have been developed using three distinct mutant alleles at the MIPS1, LPA1, and LPA2 …

Characterization of raffinose synthase genes in soybean
… the nutritional value of each component of the seed. The carbohydrate component is largely composed of sucrose, raffinose, and stachyose, which represent [about]10% of the meal. Both raffinose and stachyose are considered anti-nutritional units; sucrose is considered nutritionally useful. …

Investigation of Putative Genetic Factors Associated with Soybean [Glycine Max (L.) Merr.] Seed Quality Traits
… have improved, or altered, agronomic or seed composition traits, allowing them to be efficiently utilized in a specific niche of the processing industry. Facilitating the development of such cultivars requires a thorough understanding of the genetic factors that affect the manifestation …

Botanical Resource Use in the Bronze and Iron Age of the Central Eurasian Mountain/Steppe Interface: Decision Making in Multiresource Pastoral Economies
… also discussed in this dissertation based on the seed composition of burnt dung. The wild seeds in the assemblage indicate that herds were grazed in small forage-rich ecological pockets, rather than on the steppe proper. This system of focused herd grazing is still used today. Focusing economic …
