Pollinator Plant Communities Within Restored Montane Longleaf Pine Ecosystems, Hanen Van Rossem
Master's Theses
Historically the fire-dependent and biodiverse longleaf pine (Pinus palustris) ecosystem was the dominant ecosystem of the Southeastern US. This ecosystem’s range was massively reduced due to land conversion and fire exclusion, causing the decline of many native species. Efforts to restore and protect longleaf pine stands are now ongoing with the goal of expanding habitat and refuge for threatened species. Differences in restoration practices and prior land use may influence the extent to which restored habitat patches can support pollinators and their plants. This study compared pollinator plant biodiversity between restored neighboring montane longleaf pine stands that differed in …

Molecular Crosstalk Of Transcription Factors And Hormones In Drought Tolerance Genes In Plants, Cengi̇z Kaya
Turkish Journal of Botany
Water deficit is a critical challenge to global agricultural productivity and food security, which is exacerbated by climate change and increasing water scarcity. To withstand drought stress, plants employ a variety of molecular strategies driven by complex regulatory networks. This review examines the central role of transcription factors (TFs) as master regulators that activate drought responsive genes, which in turn mediate key adaptive processes such as osmoregulation, antioxidative defense, and membrane stability. A distinctive aspect of this review is its focus on the dynamic interplay between TFs and hormonal signaling pathways, including abscisic acid, ethylene, salicylic acid, and jasmonic acid. …

Unveiling The Physical Interaction Between Gsnor1 And Trx-H Isoforms, Anika Tabassum, Gary J. Loake
Turkish Journal of Botany
This study aims to investigate any possible interaction between two highly conserved regulators of cellular SNO levels: S-nitrosoglutathione reductase (GSNOR1) and thioredoxin (TRX). These two enzymes control global S-nitrosylation levels and thus impact the cellular redox state during immune responses. A mutant line (Δtrx1trx2sfa1) of Saccharomyces cerevisiae MaV203 strain was generated to explore this possibility rather than using a classical strain. We identified and characterized the physical interaction between GSNOR1 and Arabidopsis cytosolic h isoforms in a yeast two-hybrid screen. Out of the seven TRX isoforms, AtGSNOR1 displayed a high interaction with AtTRXh3, AtTRXh4, and AtTRXh5 (AtTRXh5>AtTRXh4 & AtTRXh3). …

Genomic Structure Among Populations Of A Regionally Rare Perennial Plant Indicates The Need For Reevaluation Of Management Units, Cheyenne Moore, Angela J. Mcdonnell, Scott Schuette, Christopher T. Martine
Faculty Journal Articles
Conservation of rare species often relies on the delineation of management units and genomic tools can now be applied for this purpose. However, this is not as common on a local scale, where populations are often small and fragmented, despite the utility of informing conservation and management practice at the regional level. We use a genotyping by sequencing (GBS) approach to assess the perennial riparian plant species Baptisia australis (Fabaceae) in Pennsylvania, where the taxon is at the edge of its natural distribution and considered threatened. In this system, we investigate whether sampled subpopulations exhibit genetic structure. We find that …

Extending Cover Crop Growing Window To Improve The Health Of Environmentally Sensitive Soils, Noshin Ara Tunazzina
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Sloping and sandy soils are highly susceptible to degradation. The health of these soils could be improved with cover crops (CCs). However, CC effectiveness in improving soil health mainly depends on CC biomass production, which is often low in temperate regions. The question is: how can we increase CC biomass production? Lengthening the CC growing window can be a potential strategy. This study assessed how 1) interseeded and terminated early (2-3 weeks before crop planting) CC, 2) interseeded and terminated late (at crop planting) CC, 3) drilled (after harvest) and terminated early CC, 4) drilled and terminated late CC, and …

Effects Of Plant Growth-Promoting Microorganisms On Microbial Community Dynamics And Plant Growth Responses Of Aeroponically Cultivated Spinach, Veronica Snow
All NMU Master's Theses
Regional food insecurity caused by the inability to use conventional farming techniques year-round in cold climates increases the need for access to quality, locally sourced, and affordable foods year-round. Shifting from a soil-based system to aeroponics can increase yields, as aeroponic systems are not weather-reliant and can operate year-round. Aeroponics, a subgroup of hydroponics, induces growth by misting nutrient-rich solutions onto the plant roots. These systems use space and water more efficiently and rely less on fertilizers and pesticides but are vulnerable to errors in nutrient application, power loss, and rapid pathogen spread. Adding Vermicompost (VCT) and plant growth-promoting microorganisms …
Chromosome Evolution Model Reveals Hidden Variation In Karyotype-Driven Speciation In Ferns,

Chromosome Evolution Model Reveals Hidden Variation In Karyotype-Driven Speciation In Ferns, Thomas Buchloh
All Theses
Because karyotype change commonly generates reproductive isolation between diverging species, rapid karyotype evolution, like that seen in plants, may increase the total rate of diversification. However, few studies have investigated this predicted relationship. Tests of this prediction have identified a positive correlation between the rate of karyotype change (specifically whole genome duplications) and diversification, but tests have been restricted to relatively small and young clades. Fortunately, novel macroevolutionary models have recently become available to investigate patterns of karyotype evolution in large phylogenies, providing new opportunity to investigate variation in karyotype driven diversification. Ferns are one of the most karyotype rich …

The vegetation of the Amazonian rainforest is hypothesized to have been shaped by pre-Columbian activities, such as burning and palm management to various extents. Management of palms is hypothesized to have caused some of the most useful species to become hyperdominant in Amazonia. This study investigated the extent to which human activities over the past 5000 years affected palm abundances in mature lowland rainforests near Iquitos, Peru. I used phytoliths and charcoal from soil cores to determine the history of local floras, and modern palm surveys to compare modern phytolith occurrence with modern vegetation. Because pre-Columbian activity clustered along the …
