Extended Data Fig. 2: Representative thin-section TEM images of chloroplasts (means ± SE) and a box plot of grana widths from dark- and light-adapted leaves of WT and of the stn7/stn8 and pph1/pbcp mutants.

N = number of grana probed per genotype and condition: WT - 291 (D), 232 (L); stn7/stn8 - 160 (D), 126 (L); pph1/pbcp - 140 (D), 140 (L). For each genotype and condition, samples were obtained from two different plants. In the box plots, the box indicates the interquartile area, whiskers are drawn down to the 5th percentile and up to the 95th, with small black squares in the middle representing the means. Scale bars: 500 nm.
