Fig. 11From: Genome-wide identification, evolutionary and expression analysis of the cyclin-dependent kinase gene family in peanutExpression patterns of different CDK and CDKL genes in roots of peanut under PEG treatment. Total RNA was extracted from roots at different time points after PEG (20%) treatment (1 h, 12 h, 24 h) and without PEG treatment (Control or 0 h) and subjected to quantitative RT–PCR analysis. Ubiquitin of peanut as an internal reference gene, the relative expression level was calculated by 2−ΔΔCt. The data are the mean ± SE of three independent biological samples. *, p < 0.05Back to article page
