Figure 1.
Functional maps of constructs. Inverted repeat MOM (IRMOM) was inserted behind (A) the PR-1 promoter (PR1-IRMOM) and (B) the CaMV 35S promoter (35S-IRMOM). (C) The control plasmid containing the PR-1 promoter but without IRMOM. Arrows above the promoters indicate direction of transcription; RB, right border; LB, left border; P35S, CaMV 35S promoter; T35S, 35S polyadenylation signal; HPT, hygromycin phosphotransferase gene; int, synthetic intron syn7 (Goodall and Filipowicz, 1989).
