Fig. 4From: Proteasome inhibition rapidly exacerbates photoinhibition and impedes recovery during high light stress in Chlamydomonas reinhardtiiThe effects of proteasome-inhibition on the ability of cells to recover from photoinhibition were evaluated using chlorophyll fluorescence. a Fv/Fm values were recorded prior to and during HL stress, and then during recovery; measurements were made every 30 min. b The ETR was estimated at the end of the 5 h recovery. Shown are the means and standard errors of five replicate cultures, which are representative of at least three other experimental replicates. Error bars are too small to plot. Asterisks represent a significant difference (p < 0.05) between treatments at each time point. Letters also represent a significant difference (p < 0.05) between treatments at each time point. LL- low light; HL- high light; R- recovery; ETR- electron transport rateBack to article page
