Schematic description of the 24 patterns based cluster analysis. The 1229 differentially expressed unisequences were classified into 24 clusters using a hierarchical algorithm. The mean signal ratio (in log2 scale) for unisequences in each cluster is plotted on the y axis. The globular-shape embryo stage was used as the reference point; the ratios of the heart-shape embryo vs. globular-shape embryo and cotyledon vs. globular-shape embryo are on the x axis from left to right, respectively. The number in each panel indicates the cluster ID.
