The ultrastructure of S-cells is not affected in GLS-deficient myb28 myb29 cyp79b2 cyp79b3 mutant plants. (A and B) Electron micrographs showing the phloem cap of vascular bundles in the top 5 mm of inflorescence stems from 6-week-old (A) wild-type and (B) mutant plants. (C and D) Electron micrographs showing the phloem cap of vascular bundles in the basal 5 mm of inflorescence stems from 6-week-old (C) wild-type and (D) mutant plants. S-cells are false-coloured in red according to their characteristic ultrastructure and size. Scale bars=20 µm.
