ToppGene functional analysis of genes changing in expression between P0 and P2. Green boxes indicate biological processes (dark) and molecular functions (light) with gray lines indicating connections to associated genes (hexagons). V$SRF_C (purple) and V$E2F_03 (yellow) boxes are transcription factor binding sites evolutionarily conserved in the promoter regions of multiple genes. Candidate targets of E2F are shown in yellow. Complete lists of molecular functions, biological processes, and transcriptional factor binding sites and associated genes are in Additional file 6.
