Abstract
Virus diseases, which decrease quality and quantity of crop yield, have importance because of thedifficulties in control. The most efficient methods to control virus diseases are use of virus-free plant material,breeding resistant varieties to viruses or vectors, controlling vector organisms to prevent the viral diseases. Recently,development of resistant varieties became one of the prevalent methods. Besides the naturally resistantvarieties, it can be obtained by classically crossing of varieties containing natural resistance genes with commercialvarieties or by genetic engineering methods in two decades. There are three main trans-gene sources to obtain resistanttransgenic plants against virus infections. Naturally resistance genes, pathogen derived resistance genes andvarious genes are obtained from the other sources. Pathogen derived resistance is commonly used comparing to theothers. These methods are based on understanding of molecular interactions in pathogenesis and interference ofthese interactions against plant pathogens. The most commonly used methods are transfer coat protein (CP) geneof target virus and gene silencing (Post Transcriptional Gene Silencing). In this review, the methods for makingresistant plants against viruses and vectors are summarized.
