Fig. 4.
Percentage of chloroplasts in wild type (WT) and TaSSIVb-D mutants (E054-13 and E1137) containing 0–2 and 3–4 granules at three different growth stages. a Seedling stage; b Elongation stage; c Heading stage. The percentage of chloroplasts equals the number chloroplasts containing 0–2 and 3–4 starch granules divided by the total number of chloroplasts observed. * means significantly different from WT at the P = 0.05 level and ** means significantly different from WT at the P = 0.01 level
