  1. *The diagonal of the matrix shows the total number of genes up (+) and down (−) regulated in each condition (underlined). Values in other positions show the number of common genes up (+) and down (−) regulated in both conditions.
  2. aGenes induced exclusively under one condition (not affected or repressed under the other conditions).
