The expression profiles derived from the cubic spline interpolations. The expression profiles after performing the cubic spline interpolations for Cry1, PhyA (pathway of circadian regulatory system of Arabidopsis thaliana) on the left-hand side, and PGI1, PGM2 (metabolic shift pathway of yeast Saccharomyces cerevisiae) on the right-hand side. The red open triangles are the raw microarray data, and the blue dotted points are the interpolation data.
