The Evolutionary Genetics Of Seed Shattering And Flowering Time, Two Weed Adaptive Traits In Us Weedy Rice, Carrie S. Thurber
The Evolutionary Genetics Of Seed Shattering And Flowering Time, Two Weed Adaptive Traits In Us Weedy Rice, Carrie S. Thurber
Open Access Dissertations
Weedy rice is a persistent weed of cultivated rice (Oryza sativa) fields worldwide, which competes with the crop and drastically reduces yields. Within the US, two main populations of genetically differentiated weedy rice exist, the straw-hulled (SH) group and the black-hulled awned (BHA) group. Current research suggests that both groups are derived from Asian cultivated rice. However, the weeds differ from the cultivated groups in various morphological traits. My research focus is on the genetic basis of two such traits: seed shattering ability and differences in flowering time. The persistence of weedy rice has been partly attributed to its ability …
Rhythmic Growth And Vascular Development In Brachypodium Distachyon, Dominick A. Matos
Rhythmic Growth And Vascular Development In Brachypodium Distachyon, Dominick A. Matos
Masters Theses 1911 - February 2014
Plants reduce inorganic carbon to synthesize biomass that is comprised of mostly polysaccharides and lignin. Growth is intricately regulated by external cues such as light, temperature, and water availability and internal cues including those generated by the circadian clock. While many aspects of polymer biosynthesis are known, their regulation and distribution within the stem are poorly understood. Plant biomass is perhaps the most abundant organic substance on Earth and can be used as feedstock for energy production. Various grass species are under development as energy crops yet several of their attributes make them challenging research subjects. Brachypodium distachyon has emerged …

Development Of A Cytosolic Ph Reporter For Tobacco By2 Cells, Michael E. Urbanowski
Masters Theses 1911 - February 2014
The regulation of pH is a critical homeostatic function of plant cells. In addition to acting as the primary cationic species responsible for energizing the plasma membrane, protons likely act as an important regulator and messenger. Despite this importance, few studies have thoroughly described cytosolic pH patterns as the plant cell progresses through the cell cycle. To investigate pH in plant cells, I chose Nicotiana tabacum (tobacco) Bright Yellow-2 (BY-2) cells as a model system. My research has two aims. First, I will measure and report the interphase cytosolic pH of BY-2 cells. Next, I will assay the cytosolic pH …
