Effects of tandem duplication, expansion, receptor configuration, and kinase signature sequence on stress responsiveness

The highest fold change during the time course was summed across biotic stress conditions and box-cox transformed to improve normality (see “Materials and Methods”).

^aRegression coefficients are on the box-cox-transformed scale (λ = −0.315).

^bP value, determined by t test, indicates whether the effect of a factor is significantly greater than zero. Significant P values (α = 0.05) are shown in boldface.

^cDummy variables are assigned values of 1 or 0 (with reference shown in parentheses).

^dNot significant after sequential Bonferroni adjustment.

^eA significant effect of E*K was observed for analysis including two potential outliers (see “Materials and Methods”).
