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 ...

The drug 4-nitroquinoline 1-oxide (4NQO) displays both carcinogenic and antitumor effects, a well known characteristic of many chemotherapeutic drugs. In addition 4NQO shares a similar operating mechanism with the commonly used chemotherapeutic drug...

throughout the circular experimental timber harvest arrays (164 m radius) by using standard radiotelemetry techniques. Prior to timber harvest, I found that wood frogs were not distributed equally throughout oak-hickory forest. Adults used drainages as non...

[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 ...

I used both demographic modeling and experimental field research to evaluate the role of terrestrial habitat in the population dynamics and conservation of pond-breeding amphibians. I began by using literature data to ...

against A. tumefaciens C58. These phages come in different shapes and sizes—from T7-like phages with podoviral morphology and isometric heads to T4-like phages with myoviral morphology and a contractile tail—and exhibit varying host ranges and killing...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Approximately 30% of breast cancers are linked with the over-expression of ErbB2. Because of its critical role in signal transduction, the progression ...

The M cell is a morphologically and functionally distinct epithelial cell found in the follicle associated epithelium (FAE) above organized lymphoid tissue at distinct locations along mucosal surfaces. By sampling antigens ...

Particularly in organisms with a limited breeding period, females must rely on both external and physiological cues to regulate the phenology of reproduction and behavior. I investigated the relationship between male ...

) The deconjugation of Atg8 from PE is essential for completion of autophagosome formation (2) Deconjugation of Atg8-PE requires Atg4 protease; (3) presence of Atg18 protein is essential for deconjugation during starvation. Here we present substantial evidence...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Light is arguably one of the most important environmental factor that not only provides the plant with its energy needs but also cues to modulate its ...

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 ...

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 ...
