Endogenous cytokinins levels in TRV, TRV-RhNAP and TRV-RhCKX6 treated petals. A The relative expression levels of RhNAP and RhCKX6 in silenced rose petal discs by qRT-PCR. RhUBI1 was used as the internal control. B The cytokinin quantification analysis. FW, fresh weight. C Expression analysis of type-A (RU12149, RU39694, RU47281) and type-B (RU00527 and RU60370) response regulator (RR) genes in RhNAP-silenced petals by qRT-PCR. RhUBI1 was used as an internal control. n = 3 ± standard deviation values are shown; Student’s t-test, *P < 0.05, **P < 0.01
