Figure 1. Construction of recombinant plasmid pRMP. pRMP contains hptII and gusA both regulated by CaMV 35S promoter, cry1Ab gene under the transcriptional control of a rubisco promoter with a nopaline synthase terminator, and located within the T-DNA right and left border sequences. Arrows indicate the direction of transcription. 35S, CaMV 35S promoter; NOS, nos polyA terminator; rbsp, rubisco promoter; 35St, CaMV 35S polyA; BR, right border; BL, left border; Km^r, kanamycin resistance.
