The quantitative relationship between the C-terminal and core domain gene induction for significantly regulated genes. a Scatterplot where each gene strongly up- or down-regulated by either domain relative to the CTD⁻/CD⁻ is represented by a single point with the induction values serving as coordinates (see Methods for criteria). The regression line and its r-squared value are calculated from a linear regression analysis performed on a log base 2 transformed set (a log transformed set is comprised of the logarithms of the original values) of the genes shown. b Scatterplot where the X coordinate equals induction by WT AvrPto relative to the CTD⁻/CD⁻, showing the induction ability of each domain versus the WT. The genes plotted are the set significantly up- or down- regulated by WT AvrPto, each gene is plotted 3 times with the same X coordinate and a variable Y coordinate based on identity, indicated by color
