Telomere Length in the Wild Type, rtbp1 Mutant Line, and 35S:RTBP1 and 35S:anti-RTBP1 Transgenic Rice Plants.

(A) Telomere length in callus, leaf, and root of wild-type plants and G1 heterozygous and G1 homozygous rtbp1 mutant lines.

(B) Marked increase in telomere length in rtbp1 mutant plants over four successive generations (G1 to G4).

(C) Enhanced telomere elongation in T2 35S:anti-RTBP1 transgenic plants (#A and #G). Pulse-field gel electrophoresis was performed more than five times independently using randomly chosen individual rice plants.
