Effects of UV shielding and DNA repair defects on resistance of unirradiated plants to H. parasitica. Leaves of wild-type (Ler), shielding defective (tt5), repair defective (uvh1-2, ercc1, uvr1-1, uvr1-1 uvr2, uvr1-1 uvr3), or shielding and repair defective (tt5 uvr1-1, tt5 uvr1-1 uvr2) plants were inoculated with HpHind4 24 h after mock UV exposure, and the number of conidiophores per leaf (light gray bars) was determined 7 d after inoculation. White bars show the number of conidiophores per leaf for plants that were grown from seed through the end of the experiment under Mylar. Only the wild-type, tt5, tt5 uvr1-1, and uvr1-1 uvr2 plants were tested this way. Data taken from Figure 4 are shown here for ease of comparison. Each column represents the mean ± se of four independent experiments.
