The Role Of Cdc42 Regulation In Cell Growth Pattern And Timing, Julie Robinson
The Role Of Cdc42 Regulation In Cell Growth Pattern And Timing, Julie Robinson
Doctoral Dissertations
In fission yeast, polarized cell growth stops during division and resumes after cell separation at the end that existed in the previous generation. It is unclear how growth occurs specifically at this end after cell division. Via a pedigree analysis of mutant cells which display a unique polarity phenotype, we show the existence of a memory of growth. This memory of growth exists at the pre-existing cell end, which grew in the previous generation, and facilitates growth at that end in the next generation. This memory of growth gives the pre-existing end some advantage in a competition for active Cdc42, …

Assessment Of Smallmouth Bass Micropterus Dolomieu And Rock Bass Ambloplites Rupestris Growth And Condition In The Little River, Tennessee, Justin Robert Wolbert
Assessment Of Smallmouth Bass Micropterus Dolomieu And Rock Bass Ambloplites Rupestris Growth And Condition In The Little River, Tennessee, Justin Robert Wolbert
Masters Theses
The Little River in Blount County, Tennessee, is a popular tourist location and fishery. It originates inside the Great Smoky Mountains National Park (GSMNP) and has sustained few impacts due to the protection of the Park. Growth and condition of smallmouth bass Micropterus dolomieu and rock bass Ambloplites rupestris were evaluated in Little River, Tennessee, from April to August 2013 and related to populations from other rivers in East Tennessee. Samples were collected via boat and backpack electrofishing. Selective sampling techniques targeting five or more fish in each 25.4- mm class produced 97 smallmouth bass and 48 rock bass. Otoliths …
Elucidating The Effect Of Silver On Ethylene Signaling In Arabidopsis Thaliana, Brittany Kathleen Mcdaniel
Elucidating The Effect Of Silver On Ethylene Signaling In Arabidopsis Thaliana, Brittany Kathleen Mcdaniel
Masters Theses
Ethylene, a gaseous plant hormone, is involved in numerous plant developmental processes such as seed germination, senescence, and fruit ripening. In Arabidopsis thaliana, ethylene is perceived by a family of five membrane-bound receptors, which upon binding ethylene trigger downstream effects. At the receptor level, it is known that the coordination of a copper ion is necessary for ethylene to bind, resulting in a conformational change of the receptor and the initiation of the ethylene signal transduction pathway. Interestingly, silver ions are also able to support binding of ethylene but ethylene responses are blocked in the presence of silver. When …
Fungal Endophytes Enhance Growth And Production Of Natural Products In Echinacea Purpurea (Moench.), Richard James Gualandi Jr.
Fungal Endophytes Enhance Growth And Production Of Natural Products In Echinacea Purpurea (Moench.), Richard James Gualandi Jr.
Masters Theses
Echinacea purpurea is a native herbaceous perennial with substantial economic value for its medicinal and ornamental qualities. Arbuscular mycorrhizae are symbiotic fungi that form relationships with plant roots and are known to enhance growth in the host. Mycorrhizae and other fungal endophytes often affect stress resistance and secondary metabolism in the host, as well as the ecology of other endophytes in the plant. A newly emerging paradigm in sustainable biotechnique is the targeted use of fungal endophytes to enhance growth and secondary metabolism in crops. Many of the therapeutic compounds in E. purpurea could be affected by fungal colonization. In …
