Fig. 1From: Regulation of rose petal dehydration tolerance and senescence by RhNAP transcription factor via the modulation of cytokinin catabolismBoth RhNAP and RhCKX6 are induced by dehydration and petal senescence. qRT-PCR analysis of RhNAP and RhCKX6 expression in rose petals in response to dehydration treatment (A, B). qRT-PCR analysis of RhNAP and RhCKX6 expression in rose petals at different opening stages (C, D). RhUBI1 was used as an internal control. All data shown are means ± standard deviation (n = 3); Student’s t-test, *P < 0.05, **P < 0.01Back to article page
