Fig. 2. vcs mutants have reduced SAM size. (A-F) SEM images of the SAM (all shown at the same magnification) of Ler (A-C) and vcs (D-F) from seedlings grown at 16°C for 15 days (A,D), 22°C for 12 days (B,E) and 29°C for 9 days (C,F). (G,H) Toluidine Blue-stained paraffin section of 14-day 29°C-grown Ler (G) and vcs-1 (H). (I,J) CSLM images of meristems from 7-day 29°C-grown Ler (I) and vcs (J). m indicates meristem. Scale bars: (A-F, I,J) 50 µm; (G,H) 100 µm.
