Cucumber mosaic cucumovirus is a plant virus in which a typical satellite RNA system is present, displaying a dualistic biological behaviour. In fact, it has been shown that satRNA is able either to aggravate or attenuate the viral disease symptomatology with a modulating capability going from death of the host plant to a surprising absence of symptoms. D-satRNA and S-satRNA have been considered the prototype necrogenic and non necrogenic satRNAs respectively. On the basis of circular dichroism spectroscopy, it is suggested that the different biological behaviours can be explained by taking into account the different capabilities exerted by S- and D-satRNAs in inducing structuring effects onto CMV-S and CMV-D genomic RNAs.
黄瓜花叶黄瓜病毒是一种存在典型卫星RNA系统的植物病毒，表现出二元生物学行为。事实上，已表明卫星RNA能够加重或减轻病毒病症状，其调节能力范围从宿主植物死亡到令人惊讶的无症状状态。D-卫星RNA和S-卫星RNA分别被认为是致坏死性和非致坏死性卫星RNA的原型。基于圆二色光谱法，有人提出，考虑到S-卫星RNA和D-卫星RNA对黄瓜花叶病毒-S（CMV-S）和黄瓜花叶病毒-D（CMV-D）基因组RNA诱导结构效应的不同能力，可以解释不同的生物学行为。
