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.
