Fig. 4From: Accumulation and regulation of anthocyanins in white and purple Tibetan Hulless Barley (Hordeum vulgare L. var. nudum Hook. f.) revealed by combined de novo transcriptomics and metabolomicsGenes differentially expressed between the two barley varieties encoding transcription factors (TFs). A Differentially expressed TFs. B Distribution of the identified differentially expressed TFs (Top 10). C Heatmap showing the 40 differentially expressed TFs between the two varieties at each stage. Cell colors correspond to the log10 magnitude of the difference in expression level [log10 (fold change values + 1)]: redder cells indicate upregulation, while bluer cells indicate downregulation. D Numbers of differentially expressed TFs between varieties at each stage Back to article page
