A：沉默NbHsc70-2后对PVY积累的影响Effect of silencing NbHsc70-2 on PVY accumulation;B：过表达NbHsc70-2后对PVY积累的影响Effect of overexpression of NbHsc70-2 on PVY accumulation
pTRV1与pTRV2::NbHsc70-2或空的pTRV2（作为阴性对照）通过根癌农杆菌共浸润培养3周的本氏烟。侵染7 d后接种PVY开始取样进行检测。pEarleyGate100:: NbHsc70-2或空的pEarleyGate100（作为阴性对照）通过根癌农杆菌共浸润培养3周的本氏烟,提前24 h接种PVY。侵染48 h后开始取样进行检测pTRV1 and pTRV2::NbHsc70-2 or empty pTRV2 (as a negative control) were co-infiltrated with A. tumefaciens for 3 weeks of N. benthamiana. Seven days after infection, PVY was inoculated and samples were taken for test. pEarleyGate100:: NbHsc70-2 or empty pEarleyGate100 (as a negative control) was inoculated with A. tumefaciens for 3 weeks and was inoculated with PVY 24 hours in advance. Sampling was taken 48 h after infection
