Regulation Of Plasmodesmata By Specialized Metabolites Glucosinolates In Arabidopsis Thaliana, Jessica C. Fernandez
Regulation Of Plasmodesmata By Specialized Metabolites Glucosinolates In Arabidopsis Thaliana, Jessica C. Fernandez
Doctoral Dissertations
Communication is an essential component to all living organisms. In
plants, the additional cell wall surrounding each cell adds a layer of complexity
not observed in animals. To overcome the literal wall separating cells, plants
have evolved specialized pores to connect adjacent cells. Plasmodesmata (PD)
allow plants to have a continuous cytoplasm between cells. Although
plasmodesmata may appear simple and lack regulation, their structural
components and their regulatory machinery is complex and not well understood.
Organelle-to-nucleus-to-plasmodesmata signaling (ONPS) have been worked as
a leading model for a possible regulatory mechanism. Many of the details of
organelle-to-nucleus retrograde signaling pathways have …
Iojap: Morphological And Physiological Phenotype Characterization In Arabidopsis, Thomas Jay Payne
Iojap: Morphological And Physiological Phenotype Characterization In Arabidopsis, Thomas Jay Payne
Doctoral Dissertations
IOJAP protein is found in all organisms that contain a ribosome of bacterial origin. The majority of studies suggest that IOJAP plays a role in translation, although this has yet to be thoroughly investigated in plants. Using Arabidopsis thaliana, an extensive phenotype characterization of iojap mutants was performed. Many processes of plant growth were slightly impaired at optimal temperature (22˚C) but became severely hindered at low temperature (12˚C and 4˚C). These cold temperature defects manifested in an overall reduction of plant growth as well as variegation, chlorosis, leaf hyponasty, as well as reduced maximum quantum yield (Fv/F …

The chloroplast is the green organelle in the plant cell responsible for harvesting energy from sunlight and converting it into sugars and ATP. Origins of this organelle can be traced back to an endosymbiotic event in which a primitive eukaryotic cell capable of oxidative phosphorylation engulfed a free-living cyanobacterium capable of photosynthetic respiration (1). Immediately following this event the details are not clear, however what is known is that over the course of evolution, the engulfed cyanobacteria relinquished approximately 97% of its protein coding sequences to the host cell nucleus, thus making the newly formed chloroplast reliant on its host …
