Figure 2. Gene expression pattern of seven leaf sections.

(A) 2,603 differentially expressed genes have been identified in the seven 3 cm leaf sections. Heatmap showing the cluster of the DEG gene expression levels in each section (from section 1 to 7, leaf base to leaf tip). (B) The expression trends of DEGs in 4 main categories clustered by K-means algorithm, and the gene number contained by each group. (C) Heatmap of KEGG enrichment for the 4 categories (-log10(q value) of each pathway).
