(A) The response curves of photosynthetic protein synthesis rate (PPSR) to photosynthetically active radiation (PAR) in Pao et al. (2019) are different between Rubisco, electron transport proteins, and light harvesting proteins, depending on the maximum synthesis rate (Smm) and the curvature (kI) of each functional protein group. The effect of fluctuating light (FL) on the photosynthetic parameters under different daily photon integral (DPI) and 12 h photoperiod was simulated with different diurnal FL patterns. (B) Daily PAR distribution (%) per hour for natural diurnal fluctuation (FLN; large fluctuation (FLL), small fluctuation (FLS), and square wave (SQ) light regimes. (C–E) The ratio of maximum carboxylation rate (Vcmax) (C), maximum electron transport rate (Jmax) (D), and leaf absorptance of PAR (E) between FL and SQ under different DPI levels. The solid and dotted green lines with arrows above (A) indicate the ranges of PAR under FLN pattern at DPI level of 5 and 20 mol m−2 d−1, respectively. (B) Adapted from Vialet-Chabrand et al., 2017. Importance of fluctuations in light on plant photosynthetic acclimation. Plant Physiology 173, 2163–2179 (www.plantphysiol.org), ‘Copyright American Society of Plant Biologists.’

The effects of FLN (Fig. 1B) on photosynthetic protein abundance depend on the values of maximum synthesis rate (Smm, equal to 0.1, 0.5, or 2.5) and the curvature (kI, equal to 0.5 or 5) of the PPSR–PAR response curves. For abbreviations see Fig. 1.
