Fig. 3 Southern hybridization of RNase L in six segregating T₂ testcross progeny. DNA was restricted with HindIII and hybridized with RNase L probe. The positions of DNA size markers are given to the left of the panel. Lanes: 1 through 6, T₂ testcross progeny; 7 non-transformed plant, negative control; 8, pRL, positive control. Comparative results of the PCR amplification of RNase L are given at the top of the panel
