The DNA A and DNA B components of a begomovirus associated with cassava mosaic disease (CMD) originating from Kerala, India, were cloned. Biolistically inoculated clones induced symptoms typical of CMD in cassava. Sequence comparisons showed the virus to be an isolate of Sri Lankan cassava mosaic virus (SLCMV). This is the first time this begomovirus species has been identified in India and only the second species shown to cause CMD in the country. The implication of these findings on our understanding of the diversity and geographic distribution of CMD-associated begomoviruses in the region and on efforts to obtain resistance to CMD are discussed.
对源自印度喀拉拉邦、与木薯花叶病（CMD）相关的双生病毒的DNA A和DNA B组分进行了克隆。通过生物射弹接种的克隆在木薯中引发了典型的CMD症状。序列比较显示该病毒是斯里兰卡木薯花叶病毒（SLCMV）的一个分离株。这是该双生病毒物种首次在印度被鉴定出来，也是该国第二种被证明可引发CMD的病毒。文中讨论了这些发现对于我们理解该地区与CMD相关的双生病毒的多样性和地理分布以及获取对CMD抗性的努力的意义。
