E Yeast two-hybrid analyses of the interactions between DJA6 and chloroplast SUF components. Positive control, the interaction between murine p53 fused with GAL4 BD and SV40 large T-antigen fused with GAL4 AD; negative control, the coexpression of Human Lamin C fused with GAL4 BD and SV40 large T-antigen fused with GAL4 AD. The dilution ratios are indicated on the left.
