Fig. 7From: Transcriptome profiling analysis for two Tibetan wild barley genotypes in responses to low nitrogenA hypothetical model of low N tolerance mechanism underlying in XZ149. Genes are shown by different colors and relative expression levels are shown by a color gradient from low (blue) to high (red). For each heatmap from left to right: XZ149-6Â h (first column), XZ149-48Â h (second column), XZ56-6Â h (third column), XZ56-48Â h (fourth column)Back to article page
