Fig. 5From: Transcriptome disclosure of hormones inducing stigma exsertion in Nicotiana tabacum by corolla shorteningqRT-PCR verification of the relative expression levels of 15 endogenous hormone-related genes in the corolla tissues of the three tobacco lines. The gene expression level of A3C was used as a reference and calculated as 1, and the relative expression level was calculated using the 2−ΔΔCt method. Data are the means ± SD of three replicates. Different letters indicate significant differences among the three lines (P < 0.05)Back to article page
