One mechanism proposed to explain high species diversity in tropical systems is strong negative conspecific density dependence (CDD), which reduces recruitment of juveniles in proximity to conspecific adult plants. Although evidence shows that plant-specific soil pathogens can drive negative CDD, trees also form key mutualisms with mycorrhizal fungi, which may counteract these effects. Across 43 large-scale forest plots worldwide, we tested whether ectomycorrhizal tree species exhibit weaker negative CDD than arbuscular mycorrhizal tree species. We further tested for conmycorrhizal density dependence (CMDD) to test for benefit from shared mutualists. We found that the strength of CDD varies systematically with mycorrhizal …

Origin, Rise And Development Of American Upland Cotton And Their Status At Present. Second Edition, Ed. By F.M. Bourland, J. O. Ware
Research Reports and Research Bulletins
American Upland cotton (Gossypium hirsutum) is a Dixie product. Although the stocks of the species were brought from elsewhere, new types (through series of adaptational changes) formed this distinctive group—the final characteristics of which are a product of the Cotton Belt of the United States. These biological processes were considerably aided by man and the steps of development possibly were about as follows: (a) natural selection took place in the earlier introductions, (b) seed were saved from the more choice stocks, (c) series of subsequent introductions were obtained from the better sources, (d) these were acclimatized and the superior ones …
A Robust Agroinfiltration Method,

A Robust Agroinfiltration Method, Bryce N. Trull
Masters Theses
Stable transformation of soybean (Glycine max) is a markedly slow and laborious process. Thus, a tool that enables rapid evaluation of genetic elements in planta is critical to advance complex research and genetic engineering in soybean. To that end, a substantially robust agroinfiltration method was innovated in this work. Agroinfiltration is a technique that leverages Agrobacterium-mediated transient transformation to deliver genetic elements to the cells of whole plant tissues, usually leaves. Several factors were found to be relevant to successful soybean leaf agroinfiltration, including genotype, surfactant, developmental stage, and Agrobacterium culture medium. The research represents not only …
Characterization Of Lignin Structural Variability And The Associated Application In Genome Wide Association Studies,

University of Tennessee, Knoxville
Characterization Of Lignin Structural Variability And The Associated Application In Genome Wide Association Studies, Nathan D. Bryant
Doctoral Dissertations
Poplar (Populus sp.) is a promising biofuel feedstock due to advantageous features such as fast growth, the ability to grow on marginal land, and relatively low lignin content. However, there is tremendous variability associated with the composition of biomass. Understanding this variability, especially in lignin, is crucial to developing and implementing financially viable, integrated biorefineries. Although lignin is typically described as being comprised of three primary monolignols (syringyl, guaiacyl, p-hydroxyphenyl), it is a highly irregular biopolymer that can incorporate non-canonical monolignols. It is also connected by a variety of interunit linkages, adding to its complexity. Secondary cell wall …

A Genome Wide Association Study Of Heat Tolerance In Snap Bean (Phaseolus Vulgaris), Morgan Stone
All Theses
Bean production in the United States has decreased while the temperatures have been steadily increasing, reaching new highs each year. Heat stress is detrimental to common bean (also known as snap bean) production. Symptoms of heat stress include decrease in pollen viability, shriveling of pods, and pod abortion making them unmarketable. Pod production of 323 snap bean accessions from a large diversity panel was assessed in a randomized complete block design with field trials at two different times in the spring season. The results show a significant decrease in the number of pods produced per plant and weight of pods …

Enabling Breeding For Fruitlet Freeze Tolerance In Peach, Ufuk Caglar
All Theses
Climate change is affecting the production of temperate fruit crops, with cold temperatures emerging as a critical abiotic stressor that limits plant growth and performance. Freeze damage, particularly in spring, has resulted in significant economic losses in peach production in the southeastern United States. Research efforts in peach and other Prunus species have primarily focused on studying dormancy-related traits associated with bloom time, such as chill and heat requirement, with fruitlet freeze tolerance not equally represented. Breeding for climate resilience in peach requires a combination of these traits to allow for late bloom via targeted chill requirement and high heat …

Evaluation Of Vegetative Indices To Determine Canopy Ground Cover For Winter Survival And Hybrid Necrosis In Winter Wheat, Micheal Young
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
The benefit of unmanned aircraft systems and image processing methods in agronomic research across numerous crops has been well documented as has the importance of wheat, Triticum aestivum L., on the global food supply. Hence there is great interest in digital solutions applied to aspects of wheat breeding. A major trait of importance to winter wheat breeders in higher latitudes is winter survival, which can result in poor yield and performance if lines do not survive extreme cold. Scoring winter survival is most commonly based on visual score of 0% to 100% with the higher percentage conveying higher winter survival …

Driscoll’S Water-Use Efficiency (Wue) Strawberry Breeding Trial, Aidan Inoue
Plant Sciences
California’s water supply is seeing stress and growers are increasingly under pressure to lower their water use. While reducing irrigation to strawberry plants can be used to raise sugars (°bx), research on the impact of deficit irrigation on plant growth, fruit yield and quality are not yet quantified. The purpose of this experiment is to observe the effects of a ~50% deficit irrigation treatment on tabletop strawberry plants where drainage measurements and plant absorption can be recorded. Results indicate that plant vigor and total marketable yield are predominantly treatment dependent whereas fruit characteristics, including culls and berry size are reliant …

The current economic environment continues to drive the need to produce record or near-record yields to be profitable. Price volatility in 2022 added another level of difficulty in the quest for being profitable. The cotton market saw significant movement after reaching a $1.5802 per pound high in May 2022, cotton prices corrected and more than halved in value at the October 2022 low, and then consolidated around the 80 cents per pound level in December 2022 (Cotton is Consolidating). Great uncertainties still exist for the upcoming season, most of which are outside of our control. These include, but are not …

Isolation Of Arabidopsis Thaliana Plants Homozygous For An Insertional Inactivation Mutation Within Atprp4., Sydney Raitz, Timothy D. Trott
Research in Biology
The AtPRP4 gene in Arabidopsis thaliana has been shown to function in several specific parts of the plant’s cell wall. It is shown to be expressed in the seeds, radicles, roots, leaves, inflorescences, and embryos of Arabidopsis thaliana. These patterns have suggested unique functions for ATPRP4 in determining cell-type-specific wall structure during the development of a plant as well as contributing to defense reactions against physical damage to the plant and pathogen infection within the plant. In this study, a simple DNA prep was performed on the true leaves of Arabidopsis thaliana. Subsequent PCR reactions were performed using …
