Genetic interactions between det1-1 and rad10 and their effect on UV-C sensitivity. (A, B) Root growth inhibition upon UV-C exposure. Four-day-old seedlings with the indicated genotypes were exposed to UV-C (600 J/m2) and immediately returned to normal light conditions (A) or to complete darkness (B) for 24 h. Relative root growth was determined 24 h after irradiation by comparison with the respective non-irradiated control of the same genotype (100% root growth). Error bars represent standard deviations from three replicate experiments (n>20). Asterisks indicate t-test significant differences at P⩽0.05 relative to wild-type controls at the same dose, while plus signs (+) indicate no significant difference with respect to the det1-1 mutant.
