烟草丛顶病研究进展

Advances of research on tobacco bushy top disease

烟草丛顶病是一类在局部地区产生严重危害的烟草病害,由烟草丛顶病毒和烟草扭脉病毒复合侵染引起。目前该病在我国仅云南有发生的报道,烟草丛顶病也是国内第一个报道的由幽影病毒属成员引起的病害。本文较为系统全面地综述了烟草丛顶病的发生与分布、病害症状学、病原物、与病害相关的dsRNA、病组织超微病变以及病害的流行及控制等方面的研究进展。

Tobacco bushy top disease was a devastating disease in some tobacco production areas. The disease was caused by a complex of two agents, tobacco bushy top virus and tobacco vein distorting virus. In China, tobacco bushy top disease was found only in western Yunnan. The disease is the fLrSt recorded plant disease associated with Umbravirus in China. The distribution, symptomology, causal agents, and dsRNAs associated with the bushy top, ultrastructural alteration, epidemiology and management of the tobacco bushy top disease were reviewed in this paper.
