A, B Total protein was extracted from 4-week-old WT, dja6, dja5, dja6 dja5 and RNAi seedlings, respectively. WT and dja6 dja5 used in (A) were grown on MS medium with 2% sucrose, while WT, dja6, dja5 and RNAi mutants used in (B) were grown on soil. 10 μg protein was loaded, except for detection with anti-SUFE1 and anti-SUFA antiserum, for which 25 μg were loaded. Specific bands were identified by immunoblotting and by their molecular weight, and are indicated by asterisks. Designations of photosynthetic protein complexes and their diagnostic components are labeled on the left and right, respectively. The Fe-S types of Fe-S proteins are shown in parentheses. Actin served as controls to normalize protein levels. For each protein, three independent biological replicates were performed and a representative one is shown.
