TRV-mediated PSY gene silencing in N. benthamiana. a Blank control (transformed using distilled water). b Negative control (transformed using empty vector). c Positive control (transformed using TRV-PDS construct). d TRV-PSY1&2 (co-transformed with TRV-PSY1 and TRV-PSY2). e Total expression of NibenPSY1–1, NibenPSY1–2, and NibenPSY2 in blank control, negative control, and TRV-PSY1&2 measured by qPCR using conserved primers. The relative expression levels in different plants were calculated by setting the gene expression value in TRV-PSY1&2 as 1. Columns and bars represent the means and standard erorrs (n = 3), respectively. Columns marked by different letters indicate P < 0.05
