Approaches To Supplementing Silicon In Soilless Media And The Value Of Silicon In The Mitigation Of Drought Stress, Mackenzie Grace Dey
All Graduate Theses and Dissertations
Silicon (Si) is not considered an essential element for plants to complete their lifecycle, but is known to be beneficial for plants under environmental stress such as drought. Unlike natural soils, Si is minimally bioavailable in soilless media. With indoor agriculture and greenhouse production increasing, the benefits of Si have been seen and Si should be supplemented. This work aimed to characterize and quantify the dissolution of Si from media substrates and additives to achieve a steady-state release of Si in soilless media. Typical media components such as coconut coir, peat moss, perlite, rock wool, sand, and vermiculite minimally released …

Evaluating Strategies For Anemone And Ranunculus Cut Flower Production In The Us Intermountain West, Shannon Rauter
All Graduate Theses and Dissertations
National growth in small-scale, specialty cut flower farms is reflected in Utah, where 145 members have joined the Utah Cut Flower Farm Association since its 2019 founding. Cool season cut flower production is limited in Utah and the Intermountain West by a narrow harvest window and elevated soil salinity. The objective of this research was to optimize production systems for anemone (Anemone coronaria L.) and ranunculus (Ranunculus asiaticus L.) in the Intermountain West by evaluating season advancement methods within a high tunnel and field production system, as well as the salinity sensitivity of each species. Fall planting dates, …

An Overview Of The Potential Effect Of Climate Change On American Pine Marten, Jordyn Morel
Honors College
The impacts of climate change are only increasing, and yet not all those impacts have been studied on certain species. The American pine marten Martes americana (Turton, 1806) is one of the species potentially vulnerable to climate change. They are an important component of biodiversity as they hunt a variety of small mammals and feed on numerous plants. Martens are also important prey to many winged and terrestrial species. In Maine, they are an umbrella species that co-occur with eleven other species and their presence is also a good indicator of a healthy forest environment. I conducted a literature review …

The Impact Of Glycine Betaine Applications On Drought Response In Wild Blueberries, Abigail Fisher
Honors College
Wild blueberries are an economically important crop for Maine, and with warming temperatures leading to increased periods of drought and increased soil moisture deficits, it is important to find new ways to combat the effects of drought. In this study, we aimed to look at the effect of foliar-applied glycine betaine applications on wild lowbush blueberries in both field and greenhouse experiments. The product being tested was Bluestim, a foliar-applied product containing >96% pure glycine betaine sold by Biobest. The product is claimed to work as an osmoprotectant allowing the plant to maintain turgor pressure and protect enzymes and macromolecules …

Characterization And Management Of Auxin-Resistant Palmer Amaranth In Tennessee, Delaney C. Foster
Doctoral Dissertations
Palmer amaranth has a long history of evolving resistance to herbicides to the point it has become a significant row crop production obstacle. Cotton and soybean growers were offered new technologies in 2016, expanding in-crop herbicide options to include dicamba or 2,4-D. Within three years of commercialization, dicamba use in these crops increased ten-fold and growers began to report Palmer amaranth escapes in west Tennessee auxin-tolerant production systems. A survey of Palmer amaranth escapes in dicamba and 2,4-D-tolerant cotton and soybean fields in Tennessee was conducted in the fall of 2021 with the objective of determining if poor control was …

Functional Analysis Of Soybean Proteinase Inhibitor Genes And Cyst Nematode-Inducible Synthetic Promoters For Insects And Nematode-Resistance In Plants, Mst Shamira Sultana
Doctoral Dissertations
Proteinase inhibitors (PIs) from legumes have the potential for use as protectants in response to pests and pathogens. Soybean (Glycine max) contains two trypsin inhibitors (TIs): Kunitz trypsin inhibitor (KTI) and Bowman-Birk inhibitor (BBI). In this study, the possible role of soybean TIs in plant defense against insects and nematodes was investigated. In addition to the three known TIs (KTI1, KTI2 and KTI3), novel inhibitors KTI5, KTI7, and BBI5 were identified in soybean. Their functional role was further examined by overexpression in soybean and Arabidopsis. In vitro enzyme inhibitory assays showed significant increase in trypsin and chymotrypsin inhibitory …

The Effects Of Deleting Lrb E3 Ligase Region 2 On Red Light Responses In Arabidopsis Thaliana, Sabina Liskey
Masters Theses
The ability of plants to absorb light through photoreceptors is essential for successful plant development. Phytochromes are important plant photoreceptors that detect and absorb red and far-red light and must function properly for plant survival. The Light Response BTB proteins (LRB) play an important role in a plant’s response to red light by degrading phytochrome B (PhyB) via the ubiquitin proteasome system (UPS). Although there has been a successful investigation into understanding the function of the LRBs, the function of a few regions within LRB proteins remains unknown, including a portion located on the N-terminal end of the protein, termed …

This budget contains costs (preplant and site preparation, establishment and maintenance, and harvest and processing) and returns for the production and sale of anemone cut flowers that were grown in a high tunnel (14 feet by 40 feet). Production methods, yield, costs, and pricing were determined from Utah State University (USU) research trials, as well as feedback from Northern Utah producers. The costs and returns represent typical production in Northern Utah but should be adjusted where necessary for individual situations. Site selection, tunnel use, variety, harvest timing, pest management, and other practices will impact costs and returns to a cut-flower …

Background: Large-diameter trees have an outsized influence on aboveground forest dynamics, composition, and structure. Although their influence on aboveground processes is well studied, their role in shaping belowground fungal communities is largely unknown. We sought to test if (H1) fungal community spatial structure matched aboveground forest structure, (H2) fungal functional guilds exhibited differential associations to aboveground tree, snag, and deadwood, and (H3) that large-diameter trees and snags have a larger influence on fungal community richness than smaller-diameter trees. We used MiSeq sequencing of fungal communities collected from soils in a spatially intensive survey in a portion of Cedar Breaks National …

Technical Note: On Uncertainties In Plant Water Isotopic Composition Following Extraction By Cryogenic Vacuum Distillation, Haoyu Diao, Philipp Schuler, Gregory R. Goldsmith, Rolf T. W. Siegwolf, Matthias Saurer, Marco M. Lehmann
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
Recent studies have challenged the interpretation of plant water isotopes obtained through cryogenic vacuum distillation (CVD) based on observations of a large 2H fractionation. These studies have hypothesized the existence of an H-atom exchange between water and organic tissue during CVD extraction with the magnitude of H exchange related to relative water content of the sample; however, clear evidence is lacking. Here, we systematically tested the uncertainties in the isotopic composition of CVD-extracted water by conducting a series of incubation and rehydration experiments using isotopically depleted water, water at natural isotope abundance, woody materials with exchangeable H, and organic materials …
