Fig. 2: Genetic epistasis analysis between AtMCM10 and ATM/ATR in DNA damage response.

a Representative phenotypes of WT, Atmcm10-1, atm, atm Atmcm10-1, atr, atr Atmcm10-1, and atm atr under genotoxic or salinity stress. Seeds were germinated on plates containing 1/2 MS medium or 1/2 MS supplemented with 5 mg/L Zeb, 2 mM HU or 100 mM NaCl, and were grown for 10 d. Bars = 1 cm. b Statistical analyses of primary root lengths of seedlings shown in (a). Data were presented as means ± SD (n = 16 seedlings), and lowercase letters indicate significant differences by one-way ANOVA followed determined by Tukey’s HSD test (p ≤ 0.05). c Representative phenotypes of WT, Atmcm10-1, atm, 35S:AtMCM10/atm, atr, 35S:AtMCM10/atr, and 35S:AtMCM10 under Zeb treatment. Seeds were germinated on plates containing 1/2 MS medium or 1/2 MS supplemented with 5 mg/L Zeb, and were grown for 10 d. Bars = 1 cm. d Statistical analyses of primary root lengths of seedlings shown in (c). Data were presented as means ± SD (n = 16 seedlings), and lowercase letters indicate significant differences by one-way ANOVA followed determined by Tukey’s HSD test (p ≤ 0.05).
