Fig. 5From: Transcriptome analysis reveals the effects of sugar metabolism and auxin and cytokinin signaling pathways on root growth and development of grafted appleClusters of annotated GO terms in the biological process category enriched in DEGs between roots of grafted WT and MB apple. DEGs were classified into specific biological process categories using DAVID with high classification stringency (P < 0.05). The horizontal ordinate represents the number of genes in the categoryBack to article page
