摘要：
Virus interactions between Tomato spotted wilt virus (TSWV) and Potato virus X (PVX) containing the nucleocapsid protein (N) gene sequences were examined to evaluate the capacity of the N gene sequences from TSWV to promote RNA-mediated cross-protection. Plants simultaneously inoculated with TSWV and PVX containing the 3′ 96bp of the N gene were highly resistant to TSWV infection, whereas no such resistance was observed in plants inoculated with TSWV and PVX containing the 5′ 96 bp. These results suggest that the 3′ portion of the N gene has a higher capacity for promoting RNA-mediated cross-protection of TSWV.
