a, b, The positions for observing CS staining in dichotomous branching (a) and lateral branching (b) species as indicated by magenta or blue bars. c, Basic fuchsin staining pictures of endodermal cell walls at the positions as shown in (a) and (b). Species marked in magenta correspond to magenta bars in (a) and those marked in white correspond to blue bars in (b). These results were independently repeated three times.
