Figure 3.—

Promoter alignment of homologous rab genes from sorghum, maize, and rice. Promoter alignments were seeded by 7/8-bp CNS identified with FootPrinter before manual adjustment. CNS are highlighted and identified by number above the sequence. CNS that do not contain biochemically characterized regulatory elements are highlighted in yellow, while CNS that contain biochemically defined motifs are highlighted in blue (ABREs), brown (DRE2), green (GRA), pink (SPH), and gray (TATA). TF-binding sites are boxed and labeled above the Zmrab17, while candidate TF-binding sites are colored red and labeled below Osrab16D. Asterisks (*) represent a sequence that can align on either side of an INDEL.
