水稻(OryzasativaL.)是全球消费的主要主食之一。全球水稻生产的一个主要障碍是植物病害造成的作物持续损失,包括稻瘟病,纹枯病,细菌性疫病,特别是各种媒介传播的水稻病毒性疾病。自19世纪末以来,全球水稻产区已记录到19种水稻病毒,对水稻生产造成不同程度的损害。其中,亚洲的南方水稻黑条矮缩病毒(SRBSDV)和水稻黑条矮缩病毒(RBSDV),非洲的水稻黄斑驳病毒(RYMV),和水稻条纹坏死病毒(RSNV)在美国目前对水稻产量构成严重威胁。这篇综述系统化了水稻病毒性疾病的出现和危害,水稻病毒的症状学和传播生物学,病毒和水稻植物及其昆虫媒介之间的军备竞赛,以及水稻病毒病的防治策略。
Rice (Oryza sativa L.) is one of the major staple foods for global consumption. A major roadblock to global rice production is persistent loss of crops caused by plant diseases, including rice blast, sheath blight, bacterial blight, and particularly various vector-borne rice viral diseases. Since the late 19th century, 19 species of rice viruses have been recorded in rice-producing areas worldwide and cause varying degrees of damage on the rice production. Among them, southern rice black-streaked dwarf virus (SRBSDV) and rice black-streaked dwarf virus (RBSDV) in Asia, rice yellow mottle virus (RYMV) in Africa, and rice stripe necrosis virus (RSNV) in America currently pose serious threats to rice yields. This
review systematizes the emergence and damage of rice viral diseases, the symptomatology and transmission biology of rice viruses, the arm races between viruses and rice plants as well as their insect vectors, and the strategies for the prevention and control of rice viral diseases.
