Fig. 7From: Transcriptome analysis in petals and leaves of chrysanthemums with different chlorophyll levelsRT-qPCR analysis of transcription factor genes differentially expressed in petals of white- and green-flowered chrysanthemum cultivars. Mean values (± SD) of three biological replicates are shown. Different letters indicate significant differences by Tukey–Kramer multiple-comparison test (P < 0.05). Designations of petal developmental stages and cultivars are as in Figs. 2 and 6 Back to article page
