Involvement Of Poly(Adp-Ribose)Ylation (Parylation) In The Regulation Of Antioxidant Defense System In Arabidopsis Thaliana Under Salt Stress, Rengi̇n Özgür Uzi̇lday

Turkish Journal of Botany

Posttranslational modifications (PTM) are one of the first responses of plants to environmental stress and involve changing the location and activity of proteins in the cell. Addition of poly(ADP-ribose) (PAR) to proteins, poly(ADP-ribose)ylation (PARylation), is a posttranslational modification resulting from the binding of ADP-ribose from NAD+ to target proteins by PAR polymerases (PARP). PARylation is involved in many physiological events in plants including abiotic and biotic stress response. The aim of this work was to understand involvement of PARylation in inducing enzymatic antioxidant defence and alternative electron sinks in response to salinity. For this purpose A. thaliana plants were treated …

Getting To The Root Cause: The Genetic Underpinnings Of Root System Architecture And Rhizodeposition In Sorghum, Farren Smith

Graduate Theses, Dissertations, and Problem Reports (ETD)

Plants are some of the most diverse organisms on earth, consisting of more than 350,000 different species. To understand the underlying processes that contributed to plant diversification, it is fundamental to identify the genetic and genomic components that facilitated various adaptations over evolutionary history. Most studies to date have focused on the underlying controls of above-ground traits such as grain and vegetation; however, little is known about the “hidden half” of plants. Root systems comprise half of the total plant structure and provide vital functions such as anchorage, resource acquisition, and storage of energy reserves. The execution of these key …

The Impacts Of Maple Syrup Production On The Herbaceous Layer In Appalachian Hardwood Forests, Logan Scott Ferguson

Graduate Theses, Dissertations, and Problem Reports (ETD)

Vegetation data were collected from eight maple syrup farms (sugarbushes) and eight undeveloped maple-dominated sites to examine potential differences in understory plant communities due to disturbance effects. Understory plants were identified to the species level and percent cover of aboveground leaf-area for each species was estimated within 600 total quadrats. Overstory data and environmental data were collected to help determine if they had any effect on herbaceous-layer plant communities. Species richness, Shannon diversity, and Pielou’s evenness were calculated, with the analysis showing no significant differences between the site types. The absolute cover of plant functional groups was also compared between …

Review Of The Duck Factory: A History Of Waterfowl In North Dakota, By Mike Jacobs And Erik Fritzell, Douglas Johnson

The Prairie Naturalist

It was by geological accident that North Dakota became the heart of duck production in the continental United States. When the Wisconsin glaciation retreated some 11,000 years ago, it left an uneven layer of glacial till over much of North Dakota and nearby states and provinces, an area termed the Prairie Pothole Region. Large blocks of ice in the glacial till eventually melted and formed depressions that became wetlands, or prairie potholes. These were embedded in a matrix of soil that, with millennia of growth by deep-rooted prairie plants, became rich topsoil. The wetlands, surrounded by luxuriant grassland, were ideal …

Understanding Morphological Responses Of Typha (Cattail) Species To Nutrient Pollution, Anna Marie Shapiro

Dissertations and Theses @ UNI

In the Midwestern United States, Typha x glauca is a hybrid of the native Typha latifolia and the non-native Typha angustifolia. Typha x glauca is considered invasive, and it is dominating Typha latifolia when they co-occur. Wetlands in the Midwest face nutrient pollution, due to fertilization used within the agricultural industry. Wetlands are nutrient sinks, which store the increased levels of nitrogen and phosphorus. These nutrients are known to increase Typha growth. Within this thesis, it was hypothesized that an increase of nitrogen in the wetland may increase the width of Typha leaves, making it difficult to distinguish the …
