Transgenic rice plants with modified PTD1 constructs encoding mutated C termini. (A) The recipient wild-type ZH11 carries a PTD1 gene encoding an endogenous wild-type protein (Endo-PTD1). (B–D) Schematic protein structures from the modified PTD1-constructs encoding different C termini, and their corresponding transgenic plants. The vertical lines indicate the positions of the conserved Cys residues in PTD1 and the mutant products. The proteins PTD1^Δ102–120 and PTD1^Δ109–120 have deletions of the segments of 102–120th aa and 109–120th aa of PTD1, respectively, and PTD1::18 aa is a recombinant protein fused with the mutant 18 aa-C terminus of Ptd1 (shaded box at the right-hand end). Scale bars are 30 cm. (This figure is available in color at JXB online.)
