Mechanistic Examination Of Protist-Mediated Plant Growth Through The Comparative Development Of Medicago Truncatula, Shane Connolly
Mechanistic Examination Of Protist-Mediated Plant Growth Through The Comparative Development Of Medicago Truncatula, Shane Connolly
University Scholar Projects
Protists are known to increase plant growth through two main mechanisms: the microbial loop and the alteration of the root microbiome. The microbial loop is a nutrient recycling method in which protists provide inorganic nitrogen ions to the plant. Alteration of root microbiome leads to the removal of plant pathogens and shifting communities towards plant growth-promoting bacteria (PGPB). This study aimed to elicit which mechanism could produce the largest boost in shoot weight for Medicago truncatula. A series of microcosm experiments were explored in which M. truncatula was grown with variable microbiome structures to allow for mechanism differentiation. The …
Enhancing Tomato Fruit Quality: Application Of Crispr/Dcas9-Mediated Methylation On The Pg Gene Promoter Region, Irena Komninakas
Enhancing Tomato Fruit Quality: Application Of Crispr/Dcas9-Mediated Methylation On The Pg Gene Promoter Region, Irena Komninakas
Holster Scholar Projects
Commercially produced tomatoes are typically harvested well before maturation in order to withstand domestic and international distribution. While this process ensures unspoiled goods, the nutritional value of the fruits have been curtailed as a result of premature harvesting. Previous research has found that the polygalacturonase gene (PG gene) is responsible for cell wall degradation of the tomato. In this study, CRISPR/dCas9 technology was employed to increase methylation levels in the promoter regions of the PG gene. This method is significant in that it epigenetically modifies the tomato genome using a technique that has the potential to develop non-genetically modified progeny …
Genetic Analysis Of Flower Color Differences Between A Hummingbird-Pollinated And A Self-Pollinated Monkeyflower (Mimulus) Species, Caitlin Foster
Genetic Analysis Of Flower Color Differences Between A Hummingbird-Pollinated And A Self-Pollinated Monkeyflower (Mimulus) Species, Caitlin Foster
University Scholar Projects
Flower color plays an important role in pollinator discrimination and speciation. Understanding the genetic contributions to flower color differences between two closely related species, Mimulus cardinalis and Mimulus parishii, can improve understanding of how they developed different pollination syndromes and diverged from a recent common ancestor. M. cardinalis is hummingbird-pollinated and has large, bright red flowers while M. parishii is self-pollinated and has small, pale pink flowers. An F2 hybrid population between these two species was created to establish a platform for analysis of the genetic architecture controlling the differences in anthocyanin pigmentation. Statistical analysis of anthocyanin concentration distribution …
An Analysis Of Crispr-Cas Gene Editing In Agriculture, Ashley Laliberte
An Analysis Of Crispr-Cas Gene Editing In Agriculture, Ashley Laliberte
Honors Scholar Theses
The CRISPR-Cas system is a promising form of gene editing, especially for the agriculture industry. The ability to make single-nucleotide edits within a gene of interest, without the need to introduce foreign DNA, is a powerful tool for designing healthier and more efficient crops and food animals. This system provides opportunity for increased nutritional value, decreased food waste, and more economically and environmentally sustainable food production. Though this biotechnology is facing mechanistic limitations due to off-target effects and inefficient homology-directed repair, vast improvements have already been made to improve its efficacy. The CRISPR-Cas system is already the most advanced form …
Ploidy Number For Panicum Virgatum (Switchgrass) From The Long Island Sound Coastal Lowland Compared To Upland And Lowland Cultivars., Tanisha Williams, Carol Auer
Ploidy Number For Panicum Virgatum (Switchgrass) From The Long Island Sound Coastal Lowland Compared To Upland And Lowland Cultivars., Tanisha Williams, Carol Auer
Plant Science Articles
Panicum virgatum L. (switchgrass) is a native, perennial grass in North America with important ecological function in ecoregions including the Long Island Sound Coastal Lowland in the Northeastern United States. In recent decades, switchgrass has become a model lignocellulosic bioenergy crop with a large research portfolio describing its distribution, genetics, genomics, phenology, traits, gene flow, and cultivation. Switchgrass has been divided into two ecotypes, the Lowland ecotype which is tetraploid (2n= 4x= 36 chromosomes) and the Upland ecotype which is tetraploid or octaploid (2n= 8x= 72). While most switchgrass research has focused on genotypes from the Midwest or Southeastern regions, …
