We found that only CNa could act as a helper virus for the replication of this satRNA. Four satRNAs, such as satY369, satY385, satC336 and satC382, were recombined with CNa respectively.

• 4个不同来源的卫星RNA(satY369、satY385、satC336和satC382)分别与CNa进行重组，结果表明：CNa可使satY369、satY385、和satC382达高拷贝量并与之稳定共存，但不能稳定支持satC336。
