From: Transcriptomic analysis reveals adaptive strategies to chronic low nitrogen in Tibetan wild barley
Average linkage hierarchical cluster analysis of transcription factors (TFs) and protein kinases (PKs) identified in differentially expressed genes (DEGs). a Transcription factors (TFs); b Protein kinases (PKs). The samples and treatments are displayed above each column. Genes are displayed by different colors. Relative levels of expression are showed by a color gradient from low (blue) to high (red)
