Figure 3. GO category enrichment of seed development-associated genes.

The enrichment of process categories associated with metabolism, development, hormone signaling and cellular regulation were shown. “Em” or “En” indicates genes that are predominantly expressed in embryo or endosperm, respectively; “Both” indicates genes that are predominantly expressed in both embryo and endosperm; “Em_T” or “En_T” indicates genes that are regulated in time during embryo or endosperm development, respectively. Chi-square test was performed to calculate the p-values, which were log10 transformed. As indicated in the scale bar, the highly enriched GO categories were in red color.
