Functional analysis of rose transcription factor gene RcWRKY41. (A) Compromised B. cinerea resistance symptoms on rose petal disks upon the silencing of RcWRKY41, shown at 60 hpi (hours post inoculation). A recombinant tobacco rattle virus (TRV) targeting RcWRKY41 (TRV-RcWRKY41) was used for the gene silencing, and an empty TRV (TRV-00) was used as the control. (B) Quantification of the average diameter of the disease lesions on the control and RcWRKY41-silenced petals at 60 hpi. Error bars = standard deviation. The statistical analysis was performed using a Student’s t-test; ** P < 0.01. (C) Quantification of RcWRKY41 expression in TRV-RcWRKY41-inoculated petal discs relative to that in the control
