Characterization Of An Ethylene Receptor In Synechocystis Sp. Pcc 6803, Randy Francis Lacey
Characterization Of An Ethylene Receptor In Synechocystis Sp. Pcc 6803, Randy Francis Lacey
Doctoral Dissertations
In plants, ethylene functions as a hormone regulating many growth and developmental processes. Ethylene receptors in plants resemble bacterial two-component signaling systems. Because of this it, ethylene receptors are thought to have been acquired by gene transfer from the cyanobacterial endosymbiont that lead to the development of the chloroplast. However, prior to this work, functional ethylene receptors were thought to only be found in green plants. Here, we show that the cyanobacterium Synechocystis sp. PCC 6803 (Synechocystis) contains a functional ethylene receptor, SynEtr1. SynEtr1 contains a predicted ethylene binding domain, a photosensory cyanobacteriochrome (CBCR) domain, and a histidine …

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 …
