Coordinated changes of gene categories activated during pod expansion. (A) Heatmap showing expression profiles of up-regulated transcripts during pod expansion. (B) Functional distribution of transcripts in analysis of pod expansion. The distribution of transcripts among the 12 categories is shown. “Others” includes “not assigned” and eight minor categories. (C,D) Significantly enriched GO categories of up-regulated transcripts during pod expansion. The BinGO, a plugin for Cytoscape, was used to draw networks for the Biological Process and Cellular Component ontologies. Node size is proportional to the number of transcripts in each category, and the significance levels are color-coded ranging from 5E⁻² to < 5E⁻⁷ (white, no significant difference; yellow, P = 0.05; orange, P < 5E⁻⁷). (E) Expression profiles of transcripts, of which the expression levels were monotonically increased during pod expansion. The transcript identifier and annotated function for each transcript were also shown.
