Transcriptional profiling of microarray data in leaves and roots. ArrayStar 3.0 was used to perform heat map clustering. Three replicates (T-DNA line had 2 replicates in the leaves) from the leaves (A) and roots (B) of 20-day-old Arabidopsis were analyzed. The color scale indicates the expression levels. Blue indicates low expression, while red stands for high expression.
