| 中文摘要: |
| 锦紫苏又名彩叶草, 是一种草本观赏植物, 可以被马铃薯纺锤块茎类病毒科锦紫苏类病毒属的类病毒侵染?目前为止, 共发现了6种锦紫苏类病毒, 分别为锦紫苏类病毒-1~锦紫苏类病毒-6(CbVd-1~CbVd-6), 它们具有共同的中央保守区(CCR), 存在广泛的分子间重组, 其嵌合体的发现为研究类病毒RNA重组提供了较为理想的试验材料?本文系统综述了锦紫苏类病毒的分类地位及分子特征?检测方法?与寄主互作等方面的研究进展, 并对锦紫苏类病毒研究中的热点和难点问题进行了讨论和展望? |
| 英文摘要: |
| Coleus (Coleus blumei) is an ornamental plant grown worldwide and can be infected by several viroids in the genus Coleviroid, family Pospiviroidae. Up to now, six viroids that infect coleus have been reported: Coleus blumei viroid-1 to Coleus blumei viroid-6 (CbVd-1—CbVd-6). They share a common central conserved region (CCR). Moreover, intermolecular recombination is common among them, and existence of chimeras provides an ideal experimental material for the study of RNA recombination in viroids. In this paper, the taxonomy, molecular characteristics, detection methods and the interactions between hosts and coleus viroids were reviewed. Furthermore, the focal and difficult problems in coleus viroids were prospected. |
