GO categories representing over or under-represented genes differentially expressed in C4 expressing seedlings relative to non-expressing seedlings. Bars represent the percentage of regulated genes in addition to those expected by chance in the Arabidopsis reference (Enrichment test). GO categories were organized into those representing up-regulated genes or those representing down-regulated genes. Blue bars indicate gene numbers and orange bars indicated fold enrichment. Categories enclosed in green rectangles are hormone related, those enclosed in the red rectangle are defense/immune related and those enclosed in the grey rectangle are cell development related. All categories had false discovery rates with P < 0.05
