Hierarchical cluster, gene ontology (GO) enrichment and KEGG analysis of 520 DEGs at 12 d after low N stress. A total of 520 DEGs were performed on a Hierarchical cluster analysis. The samples and treatments are displayed above each column. Genes are displayed by different colors and relative levels of expression are showed by a color gradient from low (blue) to high (red). b GO enrichment. c KEGG overview. X- axis depicts the different pathway; Y- axis represents the number of DEGs involving in each pathway
