a TEM pictures of representative plastids from ppi2, rpn8a ppi2, and pad1 ppi2 mutant plants. Scale-bar represents 1 µm. b Box-plot representation of the number of stacks counted from three thylakoid stacks per plastid for the three tested genotypes (n = 153 plastids, 459 thylakoid stacks). Note the median values for the number of stacks, i.e., ppi2 = 1, rpn8a ppi2 = 2, and pad1 ppi2 = 2 (bold line).
