  1. Note: aDetermined by BlastN searches performed at NCBI
  2. bChanges in gene expression pattern were defined as: N = No change in gene expression; U = Significantly up-regulated expression; D = Significant down-regulated expression; and - = No expression
  3. CNumber of times a gene responded similarly to different heavy metal stresses; represented as percentage in the table
  4. d Number of times a heavy metal stress affected different genes in a similar fashion; represented as percentage in the table. For calculations the two copies of the Tos17 were treated separately
