Abstract: The orchid virus disease seriously affects the development of orchid industry,research and exploration of orchid virus diseases prevention and control of new technologies,new ways to many researchers have become the focus of widespread concern.In this paper,the current anti-virus research in orchids of various anti-virus applications of genetic engineering strategies is summarized,which includes possible sources of the virus coat protein gene,the movement protein gene and gene-mediated resistance strategy,RNA-mediated anti-viral strategies,plants themselves anti-viral gene-mediated resistance strategy,multigene-mediated resistance strategy,and the use of antibody-mediated resistance strategy and so on.Finally,prospect in the development and application of orchid anti-virus genetic engineering is put forward.
