  1. a Functional categories of genes, total number of genes found within the rice genome, numbers of genes present on and detected on arrays, and numbers of genes showing significant differences (FDR <0.1) in transcript abundance are shown in rows and columns labeled accordingly.
  2. ROS families that are overrepresented in the response group are shown with asterisks (P < 0.05).
