Fig. 5From: Metabolic profile and transcriptome reveal the mystery of petal blotch formation in roseRelative expression level of candidate genes by qRT-PCR. Three independent biological experiments were performed. Values represent means ± SE (*p < 0.05; **p < 0.01; ***p < 0.001). B: the blotch part of the petal. NB: the non-blotch part of the petalBack to article page
