Cluster analysis of genes with statistically significant data using k-means. Genes were clustered in a pre-determined number of 12 sets using the k-means algorithm available from Gene Spring 7.2 (Silicon Genetics, CA). Sets are numbered 1–12 and the total number of genes per set is recorded. Each set contains the schematic representation of the expression profile for each one of its members. On the X axis are the different germination stage (numerator) comparisons relative to the imbibed seed (denominator) in chronological order. The Y axis show the normalized intensity for each gene at each point on a log scale.
