CONTROL OF CELL DIVISION AND DIFFERENTIATION IN THE ARABIDOPSIS ROOT - STUDIES ON THE AUXIN RESISTAN 3 (AXR3) GENE
… and formative cell divisions in the root ground tissue layer. Genetics interaction studies suggest that AXR3 acts in parallel with SCR, SHR and PLT genes, mediating patterning of the Arabidopsis root stem cell niche. Intriguingly, AXR3 expresses only in differentiated root cap cells and …

Cell Fate Specification and the Regulation of RNA-dependent DNA Methylation in the Arabidopsis Root Meristem
… root apical meristem (RAM) is a complex tissue capable of generating all the cell types that ultimately make up the root. The work presented in this thesis takes advantage of the versatility of high-throughput sequencing to address two independent questions about the root meristem. …

Effects of paper mill sludge on tree growth and competition in young red pine plantations
… 21 months following treatment in above-ground tissue, with a corresponding increase in above-ground biomass relative to controls of 22%, 33% and 85% among the 10, 20 and 40 Mg/ha treatments, respectively. An assessment of woody vegetation using a competing vegetation assessment system …

Novel Coated Fertilizers as Multi-Nutrient Sources for Soybeans and Tomatoes
… (P, S, Mn, and B) in both soils and plant tissues and the current state of chelate use in agriculture is provided along with related production issues with tomatoes and soybean. A greenhouse study investigating the ability of the first coated product (Mn + B coated KCl) to provide …

Impact of Prescribed Fire on the Terrestrial Orchid, <i>Isotria medeoloides</i> in Virginia's Blue Ridge Mountains
… but can also remain fully dormant with no above-ground tissue for multiple years. Conservation efforts over the last forty years have provided a management framework that suggests fire may be useful to recovering this flower and restoring its habitat for the benefit of the species that share it. …

Clonal integration in Ochthochloa compressa under extreme environmental conditions
… the daughters accumulated the nutrients in above ground tissue when receiving added fertilizer, and there was no sign of transference to the mother ramet. Nutrient addition did not affect in any case the efficiency photosynthetic in both mother and daughter ramets. Experiment 3. In this …

Field and Greenhouse Studies of Phytoremediation with California Native Plants for Soil Contaminated with Petroleum Hydrocarbons, PAHs, PCBs, Chlorinated Dioxins/Furans, and Heavy Metals
… for harvesting and analysis. The roots, above ground plant tissue, and soil around the roots were sampled separately and analyzed for the COIs: PHCs, PAHs, PCBs, chlorinated dioxins/furans, and metals (which include mercury, silver, cadmium, and lead). All of the plants in the field appeared to …
