RRTF overexpressor (oe18) phenotype under high light condition. (A) Phenotype of WT (Col-0), rrtf1 (RRTF1 knockout line: SALK_150614) and oe18 after 48 hours high light (HL:700 μmol/m²s) illumination. (B) Time course experiment for the change of maximum quantum efficiency of PSII photochemistry (Fv/Fm) under HL condition. (C) Deltection of intensive anthocyanin accumulation in young leaves of seedlings after 48 hour HL treatment (200 μmol/m²s). 4–5 weeks old plants, grown under short day condition (80 μmol/m²s) (A,B), and 12 days old seedlings, growing on MS plate supplemented with 1.37% sucrose under continuous low light condition (20 μmol/m²s) (C) were transferred to HL condition. Whole plant's Fv/Fm vlaues were measured with a FluorCam 700F (Photon System Instruments, Czech Republic). Astertisk: data with significant differences (n ≥ 5, t-test p <0.05).Red arrows: anthocyaninsin WT and oe18.
