Virus Induced Gene Silencing in Cold Season Cereals: the Use of Bsmv Vector

Plants developed various defense mechanisms in order to maintain their lives in nature. virus induced gene silencing (vigs) which is known as rna mediated antiviral defense mechanism is one of these mechanisms. in plants with infected unmodified viruses, the mechanism is target against the viral genome. the virus vectors carrying the target genes can be also targeted homogeneous mrnas. however, vigs has been widely used for analysis of gene function and functional genomics. these virus vectors were developed for a lot of plants. recently, barley stripe mosaic virus (bsmv) has been started utilizing for cereals. bsmv is a positive-sense rna virus with a broad experimental host range and is the type member of the hordeivirus genus. the tripartite genome consists of rnas α, β and γ. in this study, the experimental principles of bsmv vector and the knowledge about bsmv – vigs studies applied in some cereals were given.
