Figure 5.  Clustering of expression profiles of genes that show
2-fold or more change in expression in Norstar and their
comparative profiles in other genotypes. The x-axis in each
frame represents duration of cold treatment from 0 to 70 days.
The y-axis in each frame represents median centered relative
gene expression in log 2. Relative expression was calculated by
determining the difference between the maximum and minimum level
of expression in the time-series. Cluster ID is indicated by the
number on the upper left corner of each frame. The number of
genes in each cluster is indicated on the lower right corner of
each frame.  Download authors' original image
