Book Functional Significance of Membrane Modifications Induced by Brome Mosaic Virus Coat Protein

Download or read book Functional Significance of Membrane Modifications Induced by Brome Mosaic Virus Coat Protein written by Devinka Chamali Bamunusinghe and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work presented in this dissertation is divided into the following individual but related topics. In Chapter 1, subcellular localization sites of Brome mosaic virus (BMV) replication and coat protein (CP) were studied in Nicotiana benthamiana leaves using the immunofluorescence confocal microscopy. This study revealed that the BMV CP localizes to the endoplasmic reticulum (ER) membranes and replicase resides at the same location as the CP in the ER. Analysis of ultrastructural modifications by transmission electron microscopy revealed that modified ER membrane incorporate large assemblies of ER-derived vesicles during BMV infection in N. benthamiana leaves. These vesicles were encased into a vesicle pockets and three distinct types of vesicles were found in these pockets. For the first time we identified an additional function of BMV CP by ectopic expression experiments followed by TEM analysis. BMV CP itself is capable of modifying the ER membrane and induces vesicles similar to those present in BMV infection. Chapter 2 describes the analysis of functional domain of CP responsible for producing CP-induced vesicles in BMV virus infection cycle. A study analyzing the effect of mutations engineered into CP ORF on ER-rearrangement TEM microscopy in N. benthamiana leaves revealed that, assembly defective mutations encompassing either N-proximal arginine-rich RNA-binding motif (ARM; deletion from amino acid 2-20) or C-proximal 184F[arrow right]A substitution in BMV CP led to abolish the membrane rearrangement. This data suggested that encapsidation competent CP is required for the vesicle induction. Chapter 3 unfolds the implication of membrane rearrangements induced by BMV infection in susceptible and resistant hosts to viral replication and biology. Combination of Northern blot analysis, virion extraction and virion RNA extraction assays exposed that BMV causes a subliminal infection in Nicotiana clevelandii resistant host and that BMV replication efficiency in these tissues is similar to that of the Nicotiana benthamiana susceptible host. A hallmark feature of BMV CP is its inability to induce any membrane modifications in resistant host, despite efficient replication and assembly. Additional studies involving co-infection of BMV and cucumber mosaic virus (CMV) further revealed that BMV CP is more specific in genome packaging compared to that of CMV.

Book Virus Resistant Transgenic Plants  Potential Ecological Impact

Download or read book Virus Resistant Transgenic Plants Potential Ecological Impact written by Mark Tepfer and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: The introduction of novel genes into plants by genetic transformation holds great promise for plant breeding, and many crop species have been rendered virus-resistant by expression of viral sequences. However, it is essential to also evaluate the potential risks associated with this new technology. Among the types of genetically modified plants that could represent potential ecological risks, ones expressing viral sequences pose questions of particular interest. In this volume special attention is given to recombination in plants expressing sequences of RNA or DNA viruses, heterologous encapsidation or other forms of complementation in plants expressing coat protein genes, potential deleterious effects of satellite RNAs associated with cucumber mosaic virus, and sexual transmission of virus resistance genes to potentially weedy relatives.
