黄瓜花叶病毒（CMV）的Y卫星RNA（Y-satRNA）与辅助病毒一起接种烟草（Nictotianatabacum），引起烟草的亮黄色花叶症状，而在烟草上则产生绿色花叶症状。clevelandii，N.当用CMV-O加Y-satRNA接种时，bigelovii表现出黄色症状，尽管这两个野生种彼此非常接近。N. bigelovii和N. clevelandii进行杂交，以分析后代植株的症状表达。当用CMV+Y-satRNA接种时，所有F1植株最初显示淡黄色花叶，其最终变成带有黄色痕迹的绿色花叶，指示中间症状。分析了F2、F3自交植株和回交植株对CMV+Y-satRNA接种的症状反应。分离率与存在单个不完全显性基因一致，该基因参与Y-satRNA感染期间产生亮黄色症状。
Y satellite RNA(Y-satRNA) of cucumber mosaic virus (CMV) together with the helper virus induces a bright yellow symptom when inoculated on tobacco plants (Nictotiana tabacum) and develops a green mosaic symptom in N. clevelandii, while N. bigelovii exhibits a yellow symptom when inoculated with CMV-O plus Y-satRNA, even though the two wild species are very closely related to each other. N. bigelovii and N. clevelandii were crossed to analyze the symptom expression of the progeny plants. When inoculated with CMV+Y-satRNA, all the F1 plants initially showed a faint yellow mosaic, which eventually turned into a green mosaic with traces of yellow, indicating intermediate symptoms. The symptom responses of F2, F3 selfed plants, and backcross plants to inoculation with CMV+Y-satRNA were also analyzed. The segregation ratios were consistent with the presence of a single incompletely dominant gene that is involved in the production of bright yellow symptoms during infection by Y-satRNA.
