  1. * For each HvWRKY gene, the AtWRKY gene with the highest correlation value was chosen to calculate the average correlation of best pairs.
  2. ** Correlation of 101 random genes of barley and Arabidopsis. Probesets on the Barley1 GeneChip and ATH1 GeneChip were randomly selected and the average of the Pearson correlation of their expression profiles was calculated.
