The effect of proteasome inhibition on the ability of cells to recover from photoinhibition was determined by estimating cell concentration at different time points (0–10 days). Cells treated with or without MG132 were subjected to either low light or high light for two hours, and then pelleted and transferred to TP media (104 cells) and allowed to grow under LL for ten days. Shown are the means and standard errors of five replicate cultures, which are representative of at least two other experimental replicates. Error bars are too small to plot. Asterisks and different letters represent a significant difference (p < 0.05) between treatments at each time point. LL- low light; HL- high light; R- recovery; ETR- electron transport rate
