Drought is arguably the most serious environmental factor affecting crop production today. A plant's response to drought stress is extremely complex, affecting numerous metabolic pathways that are all interconnected in their responses. Due to this complex nature, scientists do not fully understand the implications of different treatments and how they affect these processes. Acetic acid has been shown to improve plant growth and resistance to drought stress, but exactly how it accomplishes this is also unknown. Soybeans (Glycine max) are one of the most important crops worldwide and can suffer significant yield loss due to drought stress. As climate change …
Optimization Of Dna Extraction From Difficult Sandy-Loam Soils, Anka Colo
Optimization Of Dna Extraction From Difficult Sandy-Loam Soils, Anka Colo
Undergraduate Student Research Internships Conference
Ginseng is a high value perennial crop grown for its roots. A four-year cultivation cycle is required to obtain marketable ginseng roots, during which a condition called ginseng replant disease (GRD) develops. GRD is characterized by a severe root rot disease, and prevents the growth of newly planted ginseng in a former ginseng garden1. Microbiome analysis of ginseng garden soil will help our understanding of the formation of GRD and its severity. However, extracting DNA from the sandy-loam soils required for ginseng cultivation is difficult. Commercial kits are either too expensive or not applicable to the large volumes of soil …
Using Wgcna For Comprehensive Understanding Of Genes Involved In Suberin Biosynthesis From Rna-Seq Data Analysis, Stephanie Wu
Using Wgcna For Comprehensive Understanding Of Genes Involved In Suberin Biosynthesis From Rna-Seq Data Analysis, Stephanie Wu
Undergraduate Student Research Internships Conference
Suberin is a heteropolymer comprising a cell wall-bound poly(phenolic) domain (SPPD) covalently linked to a poly(aliphatic) domain (SPAD) that is deposited between the cell wall and plasma membrane (Woolfson 2018). Previous studies have measured phenolic and/or fatty acid compounds in suberized tissues, and for many of these the biosynthesis is known, However, restricting analyses to only those biomolecules that are known does not yield new information about other genes that may be involved. This experiment serves to identify suberin associated gene clusters within Modules, based on an analysis of their expression patterns using Weighted Gene Correlation Network Analysis (WGCNA). Once …
Plant Biodiversity In The Face Of Climate Change: What Will Become Of Coastal Endemic Species?, Nila Le
Plant Biodiversity In The Face Of Climate Change: What Will Become Of Coastal Endemic Species?, Nila Le
Creative Activity and Research Day - CARD
How will longitudinally constrained coastal flora fare in the face of rapid anthropogenic climate change and disturbance? Coastal communities pose a unique problem for climate change and its associated risks. Species that are concentrated along the coast are naturally vulnerable to the influence of harsh abiotic ecology, such as coastal erosion and high salt concentrations. In addition, analogous to montane species-habitat interactions, coastal communities may be “pushed” off the coast edge as a result of tracking preferred climate in the face of climate variability and sea level rise. This can be problematic for species that cannot disperse quickly enough to …
Evaluating Effects Of Gene Mutation And Light Intensity On Arabidopsis Thaliana Development, Carolanne Bekus
Evaluating Effects Of Gene Mutation And Light Intensity On Arabidopsis Thaliana Development, Carolanne Bekus
Student Scholar Showcase
The completion of sequencing Arabidopsis thaliana’s genome has led to the next crucial challenge of determining gene function in these plants. A. thaliana is a model organism often compared to commercial crops. The discovery of gene function within these plants will aid in giving insight on how gene function can affect commercial crop production. Presented here is an analysis comparing wild-type Columbia (Col-O), to single gene mutants when knocking-out transcriptional factors VPI/ABI3-like 1 (val1) and basic region/leucine zipper motif (bZIP). These single gene mutations may affect several traits that in turn can result in morphological changes and/or …
Does The Fungal Pathogen (Botryosphaeria Dothidea) Exceed The Dehydration Tolerance Of Its Chaparral Host?, Cristian M. Garcia
Does The Fungal Pathogen (Botryosphaeria Dothidea) Exceed The Dehydration Tolerance Of Its Chaparral Host?, Cristian M. Garcia
Seaver College Research And Scholarly Achievement Symposium
We tested the hypothesis that an opportunistic endophytic fungus Botryosphaeria dothidea that frequently infects and causes dieback in several different species of chaparral shrubs in the Santa Monica Mountains continues to elongate and grow in host tissues at dehydration levels that exceed host survival. This was done by collecting several large branches from the field from three dominant species of co-occurring chaparral shrubs, Malosma laurina, Ceanothus spinosus, and Ceanothus megacarpus. We allowed branches to dehydrate at increasing lengths of time, from a few days to one week, in an air-conditioned laboratory, then sealed in plastic bags to allow tissuewater equilibration, …
Hydraulic Mechanisms Of Fungal-Induced Dieback In A Keystone Chaparral Species During Unprecedented Drought In California, Natalie M. Aguirre, Marissa E. Ochoa, Helen I. Holmlund, Frank E. Ewers, Stephen D. Davis
Hydraulic Mechanisms Of Fungal-Induced Dieback In A Keystone Chaparral Species During Unprecedented Drought In California, Natalie M. Aguirre, Marissa E. Ochoa, Helen I. Holmlund, Frank E. Ewers, Stephen D. Davis
Seaver College Research And Scholarly Achievement Symposium
Between 2012-2016, southern California experienced unprecedented drought that caused dieback in Malosma laurina, a keystone species of chaparral shrub communities. Dieback was especially severe in coastal exposures of the Santa Monica Mountains, leading to whole plant mortality exceeding 50% at some sites. We hypothesized that the endophytic fungus causing the dieback, Botryosphaeria dothidea, was successful in invading the xylem tissue of M. laurina because of protracted water stress, carbon starvation, or a combination of the two. We tested these possibilities in a controlled pot experiment by comparing three treatments, each inoculated with the fungus: (1) irrigated controls (2) …
Small Scale Heterogeneity In Vegetation Structure In A Patch-Burn-Grazing Landscape, Eric G. Behrens
Small Scale Heterogeneity In Vegetation Structure In A Patch-Burn-Grazing Landscape, Eric G. Behrens
UNO Student Research and Creative Activity Fair
Disturbances are drivers of spatial change in the plant communities of the tallgrass prairie ecosystem. Fire and large herbivore grazing are prevalent disturbances that maintain the vegetation structure and create spatial heterogeneity in vegetation at various scales. The fire-grazing disturbance interaction occurs when areas that have been recently burned are followed by intense grazing due to the high quality of forage regrowth. This interaction has been managed in tallgrass prairies in a homogenous method using uniform burning and grazing and a heterogeneous method using patch-burn-grazing (PBG). Vegetation heterogeneity at a large scale has been studied in PBG and uniformly managed …
The Effects Of Two Levels Of Salinity On Wisconsin Fast Plants, Megan M. Janssen, Emily Geison, Tiffany Bertoni, Matthew Zimmerman
The Effects Of Two Levels Of Salinity On Wisconsin Fast Plants, Megan M. Janssen, Emily Geison, Tiffany Bertoni, Matthew Zimmerman
Celebration of Learning
Wisconsin Fast Plant (Brassica rapa, Brassicaceae) seeds were planted in three, six-celled planting containers filled with potting soil and put beneath a continuous grow-lux light. One week after sprouting, one container (E1) was put into a separate tray filled with 0.5% NaCl solution, another container (E2) was put into a separate tray filled with 1.0% NaCl solution, and the third container was left in regular tap water. At seven-day intervals thereafter, the height of all plants was recorded, and the numbers of leaves and flowers were recorded. By week four of recording data, the average height (mm) of the control …
