Figure 2. The effect of transcription (α-amanitin) and translation (cycloheximide) inhibitors on the progress of autolysis in isolated CAPs.
A, schematic cross-section of a Lepidium sativum seed.
B, Isolated CAP (micropylar endosperm).
C, Examples of initial autolysis: CAP tip abscission (upper) and hole formation (lower).
D, Progressed autolysis.
E, The effect of inhibitors on the progress of autolysis in a population of CAPs isolated at 18h imbibition. Isolated CAPs were incubated for the times indicated without or with inhibitors (α-AM = α-amanitin; CHX = cycloheximide).
F, The effect of inhibitors on the progress of autolysis (initial + progressed lysis) in a population of CAPs isolated after 10 and 18 h of seed imbibition; subsequent incubation as indicated.
