Fig. 1From: Evaluation of reference genes for normalizing RT-qPCR in leaves and suspension cells of Cephalotaxus hainanensis under various stimuliThe RT-qPCR Ct values of 9 candidate reference genes across all samples. Expression data displayed as Ct values for each reference gene in Cephalotaxus hainanensis leaf (a) and cell (b) samples. Box graph indicates the 25th and 75th percentiles. The line across the box depicts the median. Lower and upper dashes represent the minimum and maximum values, respectively; middle circle show the mean values. *Represents the extremum valueBack to article page
