The expression profiles of 2227 soybean cDNAs in cotyledons, divided into eleven k-means clusters (PVSets). All of these genes have p-values ≤ 0.05 in at least three of the five stages. Normalized ratio intensities are shown on the Y axis. The five stages of development are marked on the X axis, from youngest to oldest (left to right): 1 = 25-50 mg, 2 = 75-100 mg, 3 = 400-500 mg, 4 = yellow, 5 = dry seed. Sets are numbered randomly by GeneSpring. Set numbers and the total number of genes per set are shown at the top of each set.
