System flow of PlantPAN. PlantPAN has two query interfaces. "Gene group analysis" discovers the co-occurrence of TFBSs in a group of gene promoters; "Promoter analysys" contains three subfunctions: "Search" and "Novel promoter sequence" search TFBSs, CpG/CpNpG islands and tandem repeats in a single input gene ID or a novel input promoter sequence; "Cross-Species" identifies TFBSs in conserved regions between homologous or two promoters.
