Brassinosteroid-Mediated Stress Tolerance In Arabidopsis Thaliana, Tawhidur Rahman Oct 2011

Brassinosteroid-Mediated Stress Tolerance In Arabidopsis Thaliana, Tawhidur Rahman

Electronic Thesis and Dissertation Repository

Brassinosteroids (BRs) are a group of steroidal plant hormones that are essential for proper plant development and also promote stress tolerance. Without BRs, plants are dwarfs and infertile. To understand the molecular mechanisms underlying BR-mediated stress tolerance, global gene expression analysis of untreated and 24-epibrassinolide (EBR)-treated Arabidopsis thaliana seedlings under non-stress and heat stress (HS) conditions was carried out. Microarray data analysis indicated that stress-related genes were predominant within the EBR up-regulated gene data set. Furthermore, several of these genes were abscisic acid (ABA) and jasmonic acid (JA) related. Measurements of endogenous hormones showed significant increases in the levels ABA …


Development Of New Platforms For Efficient Production And Purification Of Recombinant Protein In Higher Plants, Reynald Tremblay Mar 2011

Development Of New Platforms For Efficient Production And Purification Of Recombinant Protein In Higher Plants, Reynald Tremblay

Electronic Thesis and Dissertation Repository

The world-wide demand for recombinant proteins continuously increases as new medical and industrial applications are developed. Higher plants have the potential to help meet this rising demand as green bioreactors. A major hurdle, however, is low recombinant protein yields in higher plants and, as with many production systems, high cost associated with downstream purification and the production of short peptides. The goal of this research was to address each of these problems to further increase the utility of plant bioreactors. The short antigenic peptide 277 (p277) from heat shock protein 60, which has the potential for use in the prevention …
