Figure 6

Results of the TUNEL test in the root meristematic cells of ‘Sebastian’ and the hvatr.g seedlings treated with Al. (A) Examples of damaged nuclei observed in control ‘Sebastian’ roots and roots treated with 10 µM Al. Left Images of DAPI-stained nuclei. Right Images from the FITC channel. (B) Examples of damaged nuclei observed in control hvatr.g roots and roots treated with 10 µM Al. Left Images of DAPI-stained nuclei. Right Images from the FITC channel. (C) Frequency of labelled nuclei in the root cells of analyzed genotypes treated with 5 and 10 µM Al. The significant differences (P < 0.05) between the groups are indicated by different letters (uppercase letters for 'Sebastian' and lowercase letters for hvatr.g mutant).
