Fig. 5.

Heat-map showing differential gene expression based on sorghum RNA-seq dataset. The hierarchical clustering of gene expression profiling in this figure is associated with the information derived from the sorghum drought related ontology terms and the gene expression omnibus (GEO) database. The figure shows heat map depicting up and down-regulated genes under drought condition based on data from sorghum RNA-seq in response to osmotic and abscisic acid stresses. The rows represent the genes, while the columns represent the biological samples. The red color denotes the up-regulation, while the green shows down-regulation of the genes
