Over-represented molecular function and biological processes in phloem abundant transcripts. GO terms involved with DE genes between petiole-PAC and stem-PAC were analyzed with GOseq [64] to compare their enrichment in DE genes relative to the whole genome. The p-value is adjusted with BH method [97]. The over-represented genes were defined with adjusted p-value smaller than 0.05. The ratio of each GO term is calculated by dividing the number of genes involved with each GO term with number of genes in the whole group. a includes the top 20 over-represented GO terms of molecular function and (b) includes the top 20 over-represented GO terms of biological processes. c shows the GO terms related to transcription factor, flowering, light, signaling and hormone that are over-represented
