Figure 4. Expression levels of NbHSP70 are associated with the accumulation of CWMV RNAs in N.benthamiana plants.

Figure 4

(A) Symptoms in N. benthamiana plants infiltrated with the tobacco rattle virus (TRV) vector harboring a partial fragment of N. benthamiana HSP70 (TRV:NbHSP70). The empty vector (TRV:00) was infiltrated and used as a control. Pictures were taken at 7 dpi. (B) qPCR analysis showing the expression levels of NbHSP70 in the N. benthamiana infiltrated with TRV:NbHSP70 compared with the control (TRV:00). Experiments were repeated three times. Bars represent the standard errors of the means. (C) Accumulation of CWMV RNAs analyzed by Northern blotting. Total RNAs were extracted from the inoculated leaves at 4 dpi. Ethidium bromide (EtBr)-stained rRNAs are shown as loading controls. (D) Accumulation of CWMV RNA1 analyzed by Northern blotting using an RNA1-specific probe. Lane 1, the total RNA extracted from a plant inoculated with CWMV RNA 1 and RNA 2. Lane 2, the total RNA extracted from the mock inoculated N. benthamiana. Lane 3, the total RNA extracted from the silencing plants co-inoculated with CWMV RNA1 and 35S:NbHSP70. Lane 4, the total RNA extracted from the control plants inoculated with TRV:00 and CWMV RNA1. Lane 5, the total RNA extracted from the NbHSP70 silenced plants inoculated with CWMV RNA1. Lane 6, the total RNA extracted from the plants inoculated with CWMV RNA1 only. Total RNAs were extracted from the inoculated leaves 4 dpi after inoculation. Ethidium bromide (EtBr)-stained rRNAs are shown as loading controls.
