Functional analysis of rose AP2/ERF transcription factor gene RcERF099. a Compromised B. cinerea resistance upon silencing of RcERF099 (TRV- RcERF099) was observed at 60 hpi post-inoculation. b. Quantification of B. cinerea disease lesions on TRV-RcERF099- and TRV-00-inoculated rose petal discs. The graph indicates the lesion size of three biological replicates (n = 48) with the standard deviation. c. Expression of RcERF099 relative to that during the control at 6 days of post-silencing. All statistical analyses were performed using Student’s t-test; ** p < 0.01
