Characterization Of A Serine/Threonine Phosphatase Encoded By Mg_207 Of Mycoplasma Genitalium, Mario A. Martinez
Characterization Of A Serine/Threonine Phosphatase Encoded By Mg_207 Of Mycoplasma Genitalium, Mario A. Martinez
Theses and Dissertations - UTB/UTPA
Mycoplasma genitalium is a bacterium with no cell wall and the second smallest free-living organism. It is an intracellular parasite that causes urethritis in men and women. Symptoms of infection in women can be missed and include vaginal malodor and discharge, painful urination and sexual intercourse. M. genitalium infection is a serious, though preventable and treatable, infection. Recently, due its notable characteristics, many studies have revealed an enormous amount of genetic and structural information on this bacterium. Furthermore, many of its genes have been characterized. The uncovering of roles of genes involved in signal transduction via phosphorylation and dephosphorylation mechanisms …
Responses To Predator Recognition Odors In Marmorkrebs, Loren Samantha Beard
Responses To Predator Recognition Odors In Marmorkrebs, Loren Samantha Beard
Theses and Dissertations - UTB/UTPA
Marmorkrebs is a parthenogenetic crayfish with no indigenous populations. They have been introduced in several countries and could become an invasive species. Individuals introduced in Germany had longer, sharper spines, suggesting an adaptation to predators via developmental plasticity. This was tested by exposing juveniles to the odor of a fish during development and comparing them to controls. Subsequent spine length or sharpness did not differ. Other crayfish detect predators via an alarm cue, hemolymph, and exhibit avoidant behavior in response. I hypothesized that Marmorkrebs would also treat hemolymph as an alarm cue. The behavior of adult crayfish exposed to food, …
Assessment Of Oxidative Stress Gene Expression In Brassicaceae Plant Species Using A Real-Time Pcr Method, Florestella Ruiz
Assessment Of Oxidative Stress Gene Expression In Brassicaceae Plant Species Using A Real-Time Pcr Method, Florestella Ruiz
Theses and Dissertations - UTB/UTPA
Many plant species in the Brassicaceae plant family possess the ability to accumulate heavy metals. One challenge in using these hyperaccumulator plants for phytoremediation is that they are slow growing and often have a low biomass. This is a limitation should they be utilized for phytoremediation. However, the mechanisms by which hyperaccumulators tolerate heavy metals are of interest as these characteristics can be engineered into a plant species that is more suited for use in phytoremediation. Therefore, modification of oxidative stress response (OSR) gene expression in Brassicaceae species has become of great interest. Oxidative stress gene induction in both non-accumulator …
Early Embryology Of The Insect Oligotoma Saundersii (Embiidina) Using Targeted Genes As Developmental Landmarks, Omar Doria
Theses and Dissertations - UTB/UTPA
Embiidina, or "webspinners", is a small, sexually dimorphic, polyneopterous insect order and is the only order to spin silk throughout their life cycle. Unique morphological features and the phylogenetic position of Embiidina make it an attractive subject for study of the evolution and development of the insect body plan and the origin of novel morphological features. Oligotoma saundersii is easily cultured and a viable laboratory organism. It has a fairly standard short-germ embryogenesis process requiring 453 hours at 28°C with progressive development beginning in the anterior region. Preliminary work on targeted developmental genes has yielded small portions of seven genes. …
