The Role Of Cdc42 Regulation In Cell Growth Pattern And Timing, Julie Robinson Aug 2021

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, …

Elucidating The Effect Of Silver On Ethylene Signaling In Arabidopsis Thaliana, Brittany Kathleen Mcdaniel May 2012

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 …
