Figure 3.

The significantly expressed common genes involved in starch and sucrose metabolism, glycolysis, pentose phosphate pathway and galactose metabolism during the early phases of AR formation in mulberry stem hardwood cuttings. The enzyme numbers of the enriched genes are in bold, and the changes of transcriptional expression levels in the three comparison groups are illustrated with colored boxes. The boxes from left to right indicate the expression values obtained in −6 hAP vs. 0 hAP, 0 hAP vs. 54 hAP, and −6 hAP vs. 54 hAP, respectively. Each row of boxes represents a mulberry homolog gene. The color code from blue to red represents the changes of transcriptional expression level between –5 and 5. This figure is redrawn based on the KEGG pathways.
