Hierarchical cluster and gene ontology (GO) categories analysis of low N tolerance related DEGs. A total of 695 low N tolerance related 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). Gene ontology categories from three levels: (b) Molecular function; (c) Biological process; (d) Cellular component
