Increased Sensitivity to UV-C Light and Epigenetic Misregulation in r2 Mutants.
(A) Graph illustrating the survival rate of wild-type (Ler), tso2-1, rnr2a-1 rnr2b-1, and tso2-1 rnr2a-1 seedlings under increasing UV-C light levels.
(B) Twenty-five cycles of RT-PCR were used to detect TSI transcripts in 3-week-old seedlings. Lanes 1, 2, 3, and 4 correspond to the wild type (Ler), tso2-1, rnr2a-1 rnr2b-1, and tso2-1 rnr2a-1, respectively.
