Figure 5. GO category of all DEGs at the second level in roots and leaves.

The size of blue block in the outer loop indicates the DEG numbers in each GO term. The color of the outer blue loop indicates the FDR value of the GO term: a deeper color represents a smaller FDR value. The pink range indicates signification enrichment, with FDR ≤0.05 as the cutoff. (A) GO category of DEGs in roots. (B) GO category of DEGs in leaves.
