Tobacco TF expression. 772 of the 2513 TOBFAC TFs were mapped by BLAST searches to 850 probe sets on the tobacco microarray (See methods). Bar charts show the number (A) and percentage (B) of probe sets representing transcription factors in each TOBFAC family that were identified as expressed in at least one TobEA tissue type. Black bars represent the number/percentage of expressed genes and grey bars the non-expressed genes. TF families are identified along the x-axis.
