Gene ontology (GO) term "enrichment status" for the development stage-enriched transcripts in TCP. Transcript with GO term "enrichment status" and "hierarchy" in A), "molecular function"; B), "cellular component"; and C), "biological process" branches. The classification terms and their serial numbers are represented as rectangles. The numbers in brackets represent the total number of genes that may be involved in the corresponding biological processes. The graph displays the classification terms "enrichment status" and "hierarchy". The color scale shows the p- value cutoff levels for each biological process. The deeper colors represent the more significant biological processes in the putative pollen pathway.
