摘要: 玉米褪绿斑驳病毒(Maize chlorotic mottle virus,Mcmv)是番茄丛矮病毒科玉米褪绿斑驳病毒属的唯一成员,可通过机械、种子和昆虫介体传播。其单独侵染玉米仅能引起轻微症状,但其与玉米矮花叶病毒(Maize dwarf mosaic virus,Mdmv)、甘蔗花叶病毒(Sugarcane mosaic virus,Scmv)或小麦线条花叶病毒(Wheat streak mosaic virus,Wsmv)等马铃薯Y病毒科(Potyviridae)病毒复合侵染会引起严重的玉米病害——玉米致死性坏死病(Maize lethal necrosis disease,Mlnd),造成玉米产量损失惨重。Mcmv在全球广泛分布,对玉米产业构成很大威胁。深入了解Mcmv并掌握其防治措施对玉米产业的健康发展至关重要。就Mcmv的生物学特性、分布与危害、鉴定与检测及基因组结构与功能等方面的研究进展进行综述,并对其防治策略进行探讨,以期为Mcmv的深入研究和综合防治提供理论指导。

Abstract: Maize chlorotic mottle virus(Mcmv)is a sole member of the genus Machlomovirus in the family Tombusviridae. It can be transmitted by mechanical means,seeds and insect vectors. Single infections of Mcmv cause only mild symptoms while solely infecting maize. While co-infecting maize with the viruses in the family Potyviridae,such as maize dwarf mosaic virus(Mdmv),sugarcane mosaic virus(Scmv)or wheat streak mosaic virus(Wsmv),it would cause serious maize disease - maize lethal necrosis disease(Mlnd),resulting in heavy yield loss of maize. Mcmv is widely distributed around the world,posing severe threat to the maize industry. In-depth understanding Mcmv and control measures are critical to the healthy development of maize industry. In this paper,we review the research advances of Mcmv including its biological characteristics,distribution and harm,identification and detection,genome structure and function,and discuss the strategy of controlling Mcmv in order to provide theoretical guidance for in-depth research and comprehensive prevention of Mcmv.
