Fig. 5From: Root plasticity and Pi recycling within plants contribute to low-P tolerance in Tibetan wild barleyHierarchical cluster analyses of phosphate starvation response genes identified in differentially expressed genes (DEGs). a Phosphate transporters, b transcription factors, (c) sugar transport related gene, (d) auxin and abscisic acid signal pathways. The genotypes and treatments are displayed above each column. DEGs are displayed by different colors. Relative levels of expression are shown by a color gradient from low (green) to high (red)Back to article page
