Fig. 3From: Transcriptome profiling analysis for two Tibetan wild barley genotypes in responses to low nitrogenAverage linkage hierarchical cluster analysis of transcription factors (TFs) identified in differentially expressed genes (DEGs). 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)Back to article page
