Viral diseases in crop plants constitute a major obstacle to food security in the developing world. Subsistence crops, including cassava, sweetpotato, potato, banana, papaya, common bean, rice and maize are often infected with RNA and/or DNA viruses that cannot be controlled with pesticides. Hence, healthy planting materials and virus-resistant cultivars are essential for high yields of good quality. However, resistance genes are not available for all viral diseases of crop plants. Therefore, virus resistance engineered in plants using modern biotechnology methods is an important addition to the crop production toolbox.
作物病毒病是发展中国家粮食安全的主要障碍。包括木薯、甘薯、马铃薯、香蕉、木瓜、普通菜豆、水稻和玉米在内的生计作物常常受到无法用农药控制的 RNA 和/或 DNA 病毒的感染。因此，健康的种植材料和抗病毒品种对于高产优质至关重要。然而，并非所有作物病毒病都有抗性基因。因此，利用现代生物技术方法在植物中进行病毒抗性工程是作物生产工具的重要补充。
