Sliding windows of K
ratios between pairs of CBF1 , – 2 , and – 3 (A) and between CBF1 (and – 2 and – 3 ) and -4 (B). The nucleotide position was placed in correspondence to the coding region structure. The window size is 50 bp, and the step size is 10 bp. An explanation of the boxes is given in Figure 1.
