Fig. 5From: Transcriptome analysis in petals and leaves of chrysanthemums with different chlorophyll levelsRT-qPCR analysis of Chl metabolic genes in FW, FG, and FGD. Mean values (± SD) of three biological replicates are shown. Designations of petal developmental stages and cultivars are as in Fig. 2. Gene abbreviations are as in Fig. 1. The differences among petals (FW, FG, and FGD) were analyzed by Tukey–Kramer multiple-comparison test. Different letters indicate significant differences at P < 0.05Back to article page
