Commentary Plant gene silencing regularized
Two surprising and potentially useful phenomena of transgenic plants originated from two distinct lines of research but may converge in underlying mechanism or mechanisms (1–3). Plant transformation technology, the staple of the crop biotechnology industry, overcomes the species barrier and allows introduction into plants of genes from other plant species, genes from species of other kingdoms, ...
متن کاملTomato and Tobacco Phytoene Desaturase Gene Silencing by Virus-Induced Gene Silencing (VIGS) Technique
Background and Aims: Virus-Induced Gene Silencing (VIGS) is a virus vector technology that exploits antiviral defense mechanism. By infecting plants with recombinant viruses containing host genes inserted in the viral genome, VIGS achieves the RNA silencing process. The purpose of this study was to investigate the possibility of tomato (Lycopersicon esculentum Mill.) and tobacco (Nicotiana be...
متن کاملUtility of P19 Gene-Silencing Suppressor for High Level Expression of Recombinant Human Therapeutic Proteins in Plant Cells
Background: The potential of plants, as a safe and eukaryotic system, is considered in the production of recombinant therapeutic human protein today; but the expression level of heterologous proteins is limited by the post-transcriptional gene silencing (PTGS) response in this new technology. The use of viral suppressors of gene silencing can prevent PTGS and improve transient expression level ...
متن کاملVirus-induced silencing of a plant cellulose synthase gene.
Specific cDNA fragments corresponding to putative cellulose synthase genes (CesA) were inserted into potato virus X vectors for functional analysis in Nicotiana benthamiana by using virus-induced gene silencing. Plants infected with one group of cDNAs had much shorter internode lengths, small leaves, and a "dwarf" phenotype. Consistent with a loss of cell wall cellulose, abnormally large and in...
متن کاملSilencing of a plant gene by transcriptional interference
Integration of foreign DNA into eukaryotic genomes results frequently in a total or partial loss of gene function, caused by the interruption of indispensable structures of the gene itself. Using T-DNA insertions in Arabidopsis we screened for mutants with deregulated chlorophyll precursor accumulation in etiolated seedlings. A mutant designated rfd1 (red fluorescent in darkness) with increased...
