Study on Genetic Diversity of Terminal Fragment Sequence of Isolated Persian Tobacco Mosaic Virus
Tobacco mosaic virus (TMV) is one of the devastating plant viruses in the world that infects more than 200 plant species. Movement protein plays a supportive role in the movement of other plant viruses, and viral coat protein is highly expressed in infected plants and affects replication and movements of TMV. In order to investigate genetic variation in the terminal fragment sequence in Iranian...
متن کاملA Possible Explanation of the Resistance of Virus-infected Tobacco Plants to Second Infection
Leaves of tobacco plant cv. Xanthi-nc inoculated or systemically infected with potato virus Y, cucumber mosaic virus, potato virus X, potato aucuba mosaic virus or alfalfa mosaic virus showed varying degrees of resistance to infection with tobacco mosaic virus. The resistance was correlated with the appearance of at least three proteins not present in healthy plants. These were the proteins tha...
متن کاملTobacco Mosaic Virus Infection Does Not Alter the Polyadenylated Messenger R N A Content of Tobacco Leaves
Measurements of incorporation of 3H-histidine into proteins in discs from tobacco mosaic virus-infected leaves suggest that the rate of host protein synthesis is reduced by up to 75 % during virus multiplication but then recovers. Polyadenylated messenger RNAs from healthy and virus-infected plants were found to have similar size distributions and polyadenylic acid chains of similar lengths. To...
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 کاملSynthesis and localization of pathogenesis-related proteins in tobacco.
The PR1 family of pathogenesis-related proteins from tobacco (Nicotiana tabacum L.) leaves is induced by a variety of pathogenic and chemical agents and is associated with resistance to tobacco mosaic virus. The majority of the PR1 proteins did not copurify with mesophyll protoplasts (the major cell type of the leaf) isolated from tobacco mosaic virus-infected N. tabacum cv. Xanthi-nc leaves. H...
