Activation of ERF115-mediated replenishment of SSCs is a common response to SSC death induced by DNA DSBs. A and B, Expression (stained in blue) of ERF115::GUS in root tips of wild-type seedlings, which were mock-treated for 24 h (A) or treated with 13 μm zeocin for 24 h (B). C, Expression of ERF115::GUS in the root tip of a top1α seedling, which was mock-treated for 24 h. D, Expression of ERF115::GUS in the root tip of a wild-type seedling, which was treated with 100 nm CPT for 24 h. E to H, Root tips of wild-type (E), top1α (F), top1α ERF115-SRDX (G), and ERF115-SRDX (H) seedlings. I, Quantification of cell death area (µm2) in roots of 5-d-old wild-type, top1α, top1α ERF115-SRDX, and ERF115-SRDX seedlings. Error bars represent se (n > 12). Bars with different letters are significantly different at P < 0.01 (B), t test. J, Root lengths of 10-d-old wild-type, top1α, top1α ERF115-SRDX, and ERF115-SRDX seedlings. Error bars represent sd (n > 20). Bars with different letters are significantly different at P < 0.01, t test. Bars = 50 μm.
