Gene Expression Analysis of Alfalfa Seedlings Response to Acid-Aluminum

Figure 7

Pathways in response to acid-Al ions based on KEGG analysis. Overview of the combinations of the phenylpropanoid biosynthesis, phenylalanine metabolism, and flavonoid biosynthesis pathways in response to acid-Al ions based on KEGG analysis. Nineteen genes were differentially expressed in response to acid-Al ions. Hierarchical clustering of the results of the correlation coefficient analysis was shown in the lower right corner. The divided groups were marked by different shapes and color icons, which were also marked in the metabolic pathway. High positive correlation coefficient with genes in the divided groups were shown near the image of the hierarchical clustering analysis and also marked in the light shadow zone of the metabolic pathway.
