Figure 2

The schematic structure of wild-type RNA3 and Defective RNA3 (D-RNA3s). (A) The schematic structure of wild-type RNA3, D-RNA 3α, D-RNA 3β and D-RNA 3γ. The deleted regions were indicated in nucleotides, and shown by broken lines in the structures. (B) The point (underline) and deleted mutants (broken line) were introduced into the D-RNA3α, leading to the pre-termination of Ntr protein, termed as D-RNA3αM1. The second mutant D-RNA3αM2 was constructed by inserting a G(arrow) into the 110nt of RNA3, resulted into a frame-shift mutant.
