Two satellite (sat) RNAs of cucumber mosaic virus (CMV), B2- and WL3-sat RNAs, which induce systemic chlorosis on tobacco, were inoculated onto tobacco with a number of CMV strains. Systemic chlorosis was observed only when these satellite RNAs were associated with subgroup II CMV strains. Infection of tobacco with various pseudorecombinants of subgroup I and II CMV strains, together with WL3- or B2-sat RNA, suggests that chlorosis is associated with RNA 2 of subgroup II CMV strains. Chlorosis was not induced when B2- or WL3-sat RNAs were inoculated onto tobacco with tomato aspermy virus. In contrast, the induction of chlorosis on tomato by B1-sat RNA did not show any clear dependence on the subgroup of its CMV helper strain although chlorosis did tend to be more severe in association with subgroup II CMV strains.
黄瓜花叶病毒（CMV）的两种卫星（sat）RNA，即B2-和WL3-sat RNA，它们在烟草上诱导系统性褪绿，将其与多种CMV株系一起接种到烟草上。仅当这些卫星RNA与II亚组CMV株系相关联时才观察到系统性褪绿。用I亚组和II亚组CMV株系的各种假重组体以及WL3-或B2-sat RNA感染烟草，表明褪绿与II亚组CMV株系的RNA 2相关。当B2-或WL3-sat RNA与番茄不孕病毒一起接种到烟草上时，不会诱导褪绿。相反，B1-sat RNA在番茄上诱导褪绿对其CMV辅助株系的亚组没有任何明显的依赖性，尽管与II亚组CMV株系相关时褪绿往往更严重。
