Abstract :
Researchers developed many plants resistant to viruses by genetically engineering viral and non-viral genes. In Nicotiana tabacum, resistance mechanism achieved by transfering viral coat protein of tobacco mosaic virus (TMV) was the first example of this approach. Many other viral DNA sequences were determined to be effective in obtaining virus resistant plants. Among these, non-translated sense and antisense RNA, satellite RNA, defective RNA interfering, viral replicase, protease, movement proteins, and neutrelazing anticore. In addition to viral sequences or genes, non-viral plant virus resistance genes can be used to develop transgenic virus resistance plants. In this, the genes, like the other resistance genes, could be virus spesific. In spite of advantages of transgene-mediated resistance in plants, this mechanism is not widespread to date, but have potential in future applications. Briefly, in this study various recombinant DNA technologies used for increasing plant resistance to viruses and current applications will be summarized.
