Comet assay of nuclei post-IR treatment with dosages as indicated. a Nuclei collected from the leaf tissue treated with 25, 50 and 100 Gy. Non-IR treated nuclei (0 Gy) were used as controls. b The comet tail moment values from the leaf tissue post-IR treated with dosages as indicated (0, 25, 50 and 100 Gy), respectively, were analyzed using comet assay software project (CASP). One hundred typical nuclei per treatment were selected for the statistical analysis. A statistical analysis was performed using analysis of variance, where **p < 0.01. The x-axis represents the IR dosage; the y-axis represents the tail moment value
