From: Infection of Beet necrotic yellow vein virus with RNA4-encoded P31 specifically up-regulates pathogenesis-related protein 10 in Nicotiana benthamiana

Figure 1

Gene expression levels of Nicotiana benthamiana infected by Beet necrotic yellow vein virus (BNYVV) RNAs 1, 2, 3 and 4 (BN3 + 4) and a time-course investigation of PR-10 and symptoms. Normalization of expression was performed using the PP2A gene as the internal reference. Data are presented as means ± Standard Error of the Mean (SEM), *P < 0.05; n = 4/group. A control mock-inoculated sample was used as the calibrator (=1). Each experiment was repeated at least two times. (A) Expression levels of genes related to gene silencing and pathogenesis in plants at 11 dpi. (B) Time-course of PR-10 expression levels in N. benthamiana infected by BNYVV RNAs 1, 2 and 3 (BN3) and BN3 + 4 at 3, 5, 7, 11 and 15 dpi. (C) Mean height of tested plants at different times. (D) Typical symptoms on N. benthamiana. The top three or four leaves were collected. (E) PR-10 expression levels in N. benthamiana plants inoculated with several plant viruses.
