Figure 8. The root explants of the PcG mutant can form a callus normally.

(A, B) Calli of both 20 DAC root explants of wild-type Ws (A) and clf-50 swn-1 (B) are both evident. (C–F) SEM analyses showed that calli on root explants of both Ws (C, D) and clf-50 swn-1 (E, F) 6 DAC are of similar sizes. (D) and (F) are close-ups of the boxed regions in (C) and (E), respectively. Arrows indicate the newly formed calli. Bars = 2 mm in (A, B), 200 µm in (C, E), and 50 µm in (D, F).
