The parp1 mutants are more sensitive to MMS and zeocin treatments than the parp2 mutants. a Plants arrangement on the plates. b Phenotypes of Col-0 and mutants on ½ MS plates without treatment. c Phenotypes of Col-0 and mutants on ½ MS plates with 100 μg/mL MMS. d Phenotypes of Col-0 and mutants on ½ MS plates with 150 μg/mL zeocin. e Fresh weight of per eight seedlings with and without MMS treatment. f Chlorophyll content of seedlings with and without zeocin treatment. The seeds were sown on ½ MS plates, stratified for 3 d at 4 °C in the dark, and then transferred into a growth chamber with 16 h of light/8 h of dark. Two-week-old seedlings were used for the assay. Each experiment was repeated at least three times. The results are shown as the means ± SDs from three biological replicates. Two-way ANOVA with Bonferroni post hoc test analysis was performed. Different letters indicate significant differences (P < 0.05)
