Figure 7.

Cluster analysis of transcripts from Mutator (Mu, pink); bz2 (bz2, beige); and B, Pl (B, purple) plants in sunlight. RNA from b, pl green plants in sunlight was used as the reference for microarray hybridization. Clustering was performed according to Eisen et al. (1998). The color saturation reflects the magnitude of the log2 expression ratio for each transcript. Red color means higher transcript levels than the reference, whereas green means lower transcript levels than the reference. The log2 scale of color values is provided at the bottom of the figure.
