Polyamine-Induced Rapid Root Abscission in Azolla pinnata

Figure 1

Photographs of polyamine-induced rapid root abscission in A. pinnata. Photos taken (a) before and (b) after the addition of 2 mM spermine. (c)–(e) Micrographs showing a sequential process of the root detachment. (f) Micrograph of an abscised root showing rounded cells at its proximal portion. Bar represents 100 μm. The experimental conditions were similar to those in Figure 2.
