Response of atsrp3 and atsrp2 mutants to UV radiation and γ-radiation. (A) Seedlings (5-d) were exposed to UV radiation (1, 2, 3 and 10 J cm^-2) and grown at 24°C for 3 weeks. Photographs were taken on day 21 after exposure. (B) Seedlings (5-d) were grown on B5 solid media and subjected to γ-radiation at doses of zero (control) and 125 Gy. Photographs were taken 2 weeks after irradiation. (C) Expression of DNA damage-related gene RAD51 in whole seedlings (5-d) following exposure to γ-radiation was determined using semi-quantitative RT-PCR.
