Glo-3A, Glo-3B and Glo-3C putative gene structures and promoter elements for Glo3-A. (A) The gene structures for Glo-3A, Glo-3B and Glo-3C. Full boxes represent the exons. TSS and (A)n represent the transcriptional start site and polyadenylation sequences, respectively. Red arrows represent RT-PCR primers WPF1 and WPR1. (B) Glo-3A promoter region sequence and regulatory elements. Nucleotide positions start one nucleotide upstream of the start of translation at +1 (ATG). Putative regulatory elements are indicated: black underlined (CAAT element), boxed (ABRE element), dotted underlined (DOF core recognition sequence), bold neat (prolamine-box), grey underlined (Arr1), bold wave underlined (T-box), grey wave underlined (C-box), bold double underlined (pyrimidine box), dashed underlined (GATA-box), shaded (RY repeat), double underlined (E-box).
