Heatmap plot of DEGs identified by enrichment analysis at the different flowering stages, showing functional categories of significantly over-represented DEGs at S2 (a), S3 (b), S4 (c); and in LE vs. GF (d). The name of the pathway associated with each KEGG term are in Supplementary Table 4. The colour of the heatmap ranges from green (value, − 2) to red (value, + 2) on a natural logarithmic scale
