Western-blot analysis of TOC components, Tic110/Tic40 (A) and different plastid proteins involved in photosynthesis (B), in tic56-1 compared with the wild type. Rising protein amounts (top, 10, 20, and 50 µg; bottom, 2, 4, 8, and 12 µg) of 8-week-old wild-type (wt) and tic56-1 leaves were loaded and analyzed with antibodies as indicated. Detection of actin served as a loading control. In A, the ratio between the signal intensities (Int.) per µg of protein of tic56-1 and the wild type is given alongside the blots.
