↵a A “highly correlated probe” is arbitrarily defined as one with

*P*= 0 and*E*= 0, where*P*represents the probability of such a correlation coefficient arising in the entire microarray data set by chance alone and*E*represents the number of times a correlation coefficient of the stated value would arise from the entire microarray data set by chance alone (see Arabidopsis Coexpression Data Mining Tools [http://www.arabidopsis.leeds.ac.uk/act/index.php] for details).↵b Correlation values are Pearson correlation coefficients, rounded to three decimal places to save space.

↵c The number of observed probes in each column was analyzed for statistical significance by calculating the probability of a random sampling result using the hypergeometric distribution (this procedure corresponds to the Fisher exact test) as detailed in “Materials and Methods”. Significant probabilities are indicated; other entries in these columns have nonsignificant probabilities.

↵d This probe came from the Arabidopsis 8K gene array (all other probes came from the 22K gene array).
