Heat map showing up and down-regulated sorghum orthologs in maize from RNA-seq data. The comparison of gene expression pattern based on parametric (unpaired t-Test or between subject comparison, p < 0.01) and non-parametric test (Rank Product (RP), p < 0.01), and Fisher’s Exact test (p < 0.05) shows the up and down-regulated genes across treatment and tissue based grouping. Evaluation by treatment based grouping was determined to see significant difference in gene expression due to effect of differential condition under which the samples were tested while tissue based grouping was used to detect the effect of differences in tissues on the gene expression. All data showing significant expression, either up or down regulation of genes in both groupings represent results obtained under drought conditions for ovary and leaf meristem tissues
