DNA repair efficiency in maize inbred lines (B73 and Mo17) and purple Central American landraces (see Fig. 1 for abbreviations). DNA damage was compared to an untreated control. Data are mean ± SEM. Statistical analysis involved the Di Rienzo, Guzmán and Casanoves method. Different letters indicate significant differences across treatments within the same maize line or landrace at P < 0.05 (n = 3, with 3 biological replicates, 3 technical replicates and 50 nuclei per replicate)
