To investigate the relationship between satellite RNA and helper virus, satY369 was transcribed in vitro and inoculated onto N. glotinosa plants together with CNa to form a pseudorecombinant virus (NY).

• 接种1 od，NY与CNa的寄主适应性没有显著差异，新毒株NY的基因组RNA3在六种寄主植物中的相对含量依次为番茄>假酸浆>心叶烟>西葫芦>南瓜>曼陀罗，其卫星RNA一satY369在寄主中的相对含量则表现为假酸浆>心叶烟>番茄>曼陀罗>西葫芦>南瓜。
