Fig. 4

Photosynthesis dynamics of A. thaliana accessions Col-0 (blue) and Ely (orange) at individual plant level. Schematic representation of the fluctuating light treatment over time is shown in the top panel, with 300 µmol m⁻² s⁻¹ of constant irradiance, 100 µmol m⁻² s⁻¹ of low irradiance and 900 µmol m⁻² s⁻¹ of high irradiance levels. Maximum quantum yield (F_v/F_m, A) and photosystem II efficiency (ϕPSII, B) are plotted against time (as timepoint or as days after sowing, DAS). The variation for these traits is shown as shaded regions around the mean of 8 replicates (solid line) for each accession
