Scatterplot comparisons of independent qPCR measurements. Scatterplot comparisons of independent qPCR measurements; all values are relative to the amount in the Col-0 standard. (A) DNA concentration in ten samples as determined by separate qPCR of two singlecopy genes, ROC1 and ACT2. The linear regression between the two sets accounts for 96% of their variance (p-value ~10⁶). (B) Copy number of the of 45S RNA gene's 18S and 25S subunits, measured separately, from Table 2. Here linear regression accounts for 71% of their variance (p-value < 0.01). Horizontal and vertical bars present the standard error of the mean.
