*4.8. Tissue Expression Profile and Microarray Analysis*

Expression patterns of 46 *ZmTCPs* in different maize tissues were analyzed using the genome-wide gene expression atlas of the inbred B73 line of maize that was reported previously [43]. Expression data for the 15 tissues were combined from 60 growth stages. Normalized expression values of each gene in different tissues were averaged. The gene expression level was presented as a log value. To analyze the gene expression patterns of *ZmTCPs* in maize during drought stress, the microarray data and analysis methods were employed as described previously [63].
