The Arabidopsis GAMYB-like genes promote aleurone PCD. A, Number of PSVs per aleurone cell in wild-type Columbia-0 (Col) and myb33.myb65.myb101 (triple mutant) seeds at different time points during germination. n = 50 cells, and sd ranges from 0 to 7.71. Error bars have been omitted for clarity. B and C, Typical images of aleurone cells incubated at 30°C for 5 d without (B) and with (C) GA. D, Percentage of vacuolated aleurone layers after 5 d of incubation at 30°C with or without GA (n = 20).
