VIGS-OHP1 plants are susceptible to high light intensities.

(a) Measurement of Fv/Fm ratios in leaf discs of VIGS-GFP and VIGS-OHP1 plants after exposure to high light (850 µmol photons s⁻¹ m⁻²). False colors indicate Fv/Fm ratios and numerical values of the color code are indicated. One representative leaf disc for each time-point is shown. (b) Numeric representation of Fv/Fm ratios displayed in A. Data are normalized to Fv/Fm in VIGS-GFP at time-point t₀, which is set to 100%. Mean values and standard deviations of three biological replicates are shown. B, Western blot analysis of OHP variants and D1 from leaf discs of VIGS-GFP and VIGS-OHP1 plants exposed to HL as described above. Ponceau S staining of the large subunit of RuBisCO (RbcL) is shown as the loading control.
