acid transporter, in restricted placentae.These changes in placentae from dams fed a nutrient restricted diet suggestsome compensation to ensure adequate nutrients are available to the fetus forproper development.I also examined the effects MUN...

Mutualisms are ubiquitous in nature, yet these interactions often vary in strength and persistence. This variation raises the questions of what determines whether mutualisms persist or vanish, and how does variation in the ...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] In A. tumefaciens, the essential FtsZ protein is located at the growth pole before shifting to the mid-cell right before division. Recruitment of FtsZ to mid-cell is required...

Development of the nervous system is characterized by intricate processes like neuronal migration, axon outgrowth and guidance and synaptic connections to their targets. These processes involve navigation of the migrating ...

While there are many types of habitat loss and degradation (e.g., agriculture, land development), many studies have focused on the impacts of logging on wildlife populations and on ecosystem processes. Little information, ...

In plants, conventional genetic engineering methods limit the number of available traits that could potentially improve the quality of agriculture. Agrobacterium-mediated transformation and biolistic bombardment are tools ...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Ceramides are intimately involved in a wide range of cellular processes. In mammals, de novo ceramide synthesis is catalyzed by the 6 ceramide synthase enzymes, which...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Phylogenetic trees show us how organisms are related and provide frameworks for studying and testing evolutionary hypotheses. To better understand the evolution of orchids...

Adult muscle stem cells or satellite cells are the committed somatic stem cells responsible for maintenance and regeneration of adult skeletal muscle tissue. Skeletal muscle is capable of multiple rounds of complete ...

Species distributions are governed by a complex suite of abiotic and biotic interactions that govern movement of individuals and are variable through time and space. These dynamic processes, such as shifts in temperature ...

Introduction: Intervertebral disc (IVD) degeneration is a significant cause of back pain and disability. Factors such as trauma and magnitude and frequency of loading are associated with IVD degeneration. However, the ...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The development of a complex organism, such as a plant, requires the function of multiple pathways that regulate various aspects of the developmental process. Here pathways...

Carbohydrate partitioning, the process of transporting carbohydrates from sites of synthesis in hotosynthetic tissue to developing sink tissues, is crucial for the growth, development, and yield in plants and crops. ...

The research presented here was focused on the effects of interactions between Nicotiana longiflora and N. plumbaginifolia on their mating systems. First, I conducted a series of observations and pollination experiments ...

Ionic currents drive cellular function within all living cells to perform highly specific tasks. For excitable cells, such as muscle and neurons, voltage-gated ion channels have finely tuned kinetics that allow the ...

Reversible and easy to use, temperature-sensitive (TS) mutations, are powerful tools to study the functions of all genes, including essential and pleiotropic ones. However, the rarity of TS alleles and the difficulty of ...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Xenoestrogens (XE) are chemicals in the environment that mimic the body's natural steroidal estrogens. Developmental exposure to XE may interfere with normal hormonal signaling...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Unconventional oil and gas (UOG) processes involves injection of pressurized water, chemicals, and suspended solids thousands of feet under the surface to release natural gas...

Understanding how bacterial cells expand their cell walls is an important question with relevance to development of antibiotics. While many studies have focused on the regulation of bacterial elongation utilizing lateral ...

Partner abundance affects costs and benefits in obligate mutualisms, but its role in facultative partnerships is less clear. I investigated this topic in a small alpine pollination web in the Colorado Rocky Mountains ...
