【Abstract】 Different strategies in genetic engineering breeding for plant resistance to viral diseases in recent years were reviewed .These strategies include host gene mediated resistance strategies and pathogen derived resistance strategies,which involve viral coat protein gene,movement protein gene,replicase gene,satellite RNA,antisense RNA,and defective interfering RNA.In addition,antibody gene,ribozyme and interferon also have the ability to confer resistance against plant viruses.Meanwhile,resistance mechanisms and the perspective of application of each strategy were briefly discussed.更多还原
