甘蔗黄叶病是由甘蔗黄叶病毒(Sugarcane yellow leaf virus,SCYLV)引起的一种病毒病害,在全球主要甘蔗种植国家或地区普遍发生,危害日益严重。SCYLV经甘蔗蚜虫以持久性方式传播,在寄主植株内主要侵染韧皮部组织。该病毒起源于黄症病毒科属间基因重组,被国际病毒分类命名委员会确认为黄症病毒科马铃薯卷叶病毒属成员。文章综述了甘蔗黄叶病毒生物学特征、病害发生和危害、病原鉴定和检测、分子进化和遗传多样性、基因组结构和基因功能以及抗病转基因等方面研究进展,并对甘蔗黄叶病抗病育种和防治措施作了讨论。
Sugarcane yellow leaf disease is a virus disease caused by Sugarcane yellow leaf virus (SCYLV), which is a common disease in the main sugar cane growing countries around the world and is endangered. SCYLV is propagated persistently via sugarcane aphids and infects phloem tissues primarily in host plants. The virus originated in the genus of the Flaviviridae gene recombination, the International Virus Classification Nomenclature Committee identified as a member of the Flaviviridae family of potato leaf virus. In this paper, the biological characteristics, disease occurrence and damage, identification and detection of pathogen, molecular evolution and genetic diversity, genome structure and gene function as well as disease-resistant transgenic and so on were reviewed in this paper. Breeding and control measures were discussed.
