The role of polyphenols and the cell wall in relation to the desiccation tolerance of the resurrection plant, Myrothamnus flabellifolia (Welw.)
Resurrection plants are unique in that their vegetative tissue has the ability of survive reversible dehydration to an air-dry state. The widespread African resurrection plant Myrothamnus flabellifolia (Welw), woody shrub, is one of the largest of these plants. In addition to its resurrection …

Regulation of desiccation tolerance in Xerophyta seedlings and leaves
… angiosperms known as resurrection plants display vegetative desiccation tolerance and can survive loss of up to 95% of cellular water, a feat only seen in the seeds and pollen of other angiosperms. Xerophyta humilis is a resurrection plant native to Southern Africa that has been the target of …

The Comparative Anatomy of Extrafloral Nectaries in the Cactus Family (Cactaceae)
… from stomata in foliage leaves or modified leaf tissue. These stomata are located over subjacent vascular tissue with type 3a EFNs being associated with vegetative tissue and type 3b EFNs located on the exterior of pericarpel. Type 4 EFNs are also associated with leaf tissue but secrete nectar …

Interrelationships between Soybean Seed Quality Characteristics
… that limiting amino acids may be supplied by the vegetative tissue under C-limited conditions. The ultimate goal of soybean seed improvement is to increase yield while also increasing or maintaining seed protein concentration and the balance of the limiting amino acids. Meeting two of these goals …

Effects of Drought on Gene Expression in Maize Reproductive and Leaf Meristem Tissues as Revealed by Deep Sequencing
… The effects of drought on early reproductive tissue at 1-2 DAP (days after pollination) is irreversible in nature and leads to embryo abortion, directly affecting the grain yield production. We developed a working RNA-Seq pipeline to study maize (Zea mays) drought transcriptome sequenced by …

The Role of Arabidopsis thaliana P80 in Inositol Signaling
… that InsP7 is present in developing seeds and vegetative tissue of higher plants. I have also demonstrated that p80 mutants have an alteration in the levels of PPx-InsPs. In addition, I have established spatial expression patterns of two enzymes involved in the synthesis of PPx-InsPx, known as …

Association Mapping for Elemental Concentration Resulting from Vegetative Stage Soil Waterlogging Stress in Wheat (Triticum aestivum L.)
… to identify SNP associated with the EC in the vegetative tissue of a set of 240 diverse soft winter wheat genotypes (AM panel) grown under field WL and to determine the impact of WL on wheat yield (GY) and yield components in a set 28 adapted cultivars (YT)</p> <p>YT study showed reductions in …

Characterization of membrane lipids and, Changes therein during desiccation and rehydration of the resurrection plant Xerophyta humilis (Bak) Dur and Schinz
… up to 95% of their cellular water content in vegetative tissue upon extended periods of water, remain in an air-dry for months to years and regain full metabolic activity in the same tissue upon re-watering. The aim of this study was to investigate the changes in acyl chain composition within …

Evaluation of hydrothermal pretreatment and fermentation to improve lipid and ethanol production from corn germ meal
… engineering of plants to accumulate oil in vegetative tissue is a potential future source of vegetable oil that promises increased land productivity and use of marginal lands. However, low concentrations of lipids in current engineered plant biomass samples makes extracting the oil …

Arabidopsis thaliana P4-type ATPases ALA4 and ALA5 are Necessary for Normal Cellular Elongation in Developing Vegetative Tissues and Rescue the Pollen Tube Deficiencies in Knockout ala6/7 Mutants
… critical for normal growth and development of vegetative tissues. A double loss of function mutant for ala4/5 results in dwarfism for all vegetative tissues, including roots, leaves and hypocotyls. Selected cell types in these tissues were shown to be smaller. While a restoration of growth to …
