Fig. 6. The nucleotide sequence of the amplified 5′ upstream promoter region of HbPIP1;1 (A), and its diagram (B) the promoter sequence of HbPIP1;1 was cloned, sequenced and analyzed for putative cis-acting sequences using the PLACE software. The translational start site is labeled +1. The negative numbers represent the upstream ends of the promoter fragments. The putative CAAT box and TATA box, as well as various putative regulatory motifs, are boxed and labeled under the sequences. These motifs include the ethylene responsive element (ERE), auxin responsive factor (ARF), dehydration responsive element (MYB, MYC), organ specific element (OSE2), gibberellin responsive element (GARE, Pyrimidine box, WRKY) and wound responsive box (W box).
