PNT1 regulates a subset of phytochrome-mediated light responses. (A) Seedlings displaying more severe (PNT1-OXs) or less severe [pnt1 mutants: pnt1-1 (Col-0) and pnt1-2 (Ws-2)] photobleaching than wild-type plants (Col-0 and Ws-2) are shown. FR (2.4 μmol/m2/s)-grown seedlings were transferred to white light (100 μmol/m2/s) for 4 d. Genomic structure of PNT1 with two T-DNA insertion sites (inverted triangles) and transgenes for two PNT1-Oxs are shown. (B) Quantification of remaining chlorophylls after transferring FR-grown seedlings of various ages to white light for 4 d (SD, n = 3).
