Assessment of basal heat tolerance in 7-day-old Col seedlings. (A-B) Seedlings were subjected to a 45°C heat shock for different time periods (0–45 min). (C-D) Seedlings were subjected to a 20 min heat shock in a range of different temperatures (38-50°C). Seedling survival was scored after a 6-day recovery period, and represented as a percentage of initial viable seedlings. Error bars represent SEM (n = 5 plates with ~25 seedlings each).
