花叶病是最主要的甘蔗病毒病害之一,在全球种植甘蔗的国家或地区普遍发生,可导致甘蔗产量下降,糖分减少,给甘蔗生产带来严重的经济损失。引起甘蔗花叶病的病毒主要有甘蔗花叶病毒(Sugarcane mosaic virus,SCMV)、高粱花叶病毒(Sorghum mosaic virus,Sr MV)和甘蔗条纹花叶病毒(Sugarcane streak mosaic virus,SCSMV)。本文综述了这3种病毒的生物学特性、鉴定与检测、基因组结构与基因功能、遗传变异与分子进化等方面的研究进展,并讨论了对甘蔗花叶病的生态防控措施。
Mosaic disease is one of the most important diseases of sugarcane virus. It is common in the countries or regions that plant sugarcane around the world. It can lead to the decrease of sugarcane production and the decrease of sugar content, resulting in serious economic losses to sugar cane production. Sugarcane mosaic virus (SCMV), Sorghum mosaic virus (Sr MV) and Sugarcane streak mosaic virus (SCSMV) are the main causative viruses of sugarcane mosaic disease. This review summarizes the biological characteristics, identification and detection, genomic structure and gene function, genetic variation and molecular evolution of these three viruses, and discusses the ecological control measures for sugarcane mosaic disease.
