HPT and NHPT seedlings of the indicated genotypes were subjected to anoxia in the presence of 100 mm Glc and 250 μg mL−1 cefotaxime for 5 or 24 h. Each ratio is from an independent experiment and represents the number of seedlings that had elongated with respect to the total number of seedlings. The percentage is calculated from the sum of the seedlings that had elongated and the total number of seedlings.
