Figure 6From: Defects in leaf carbohydrate metabolism compromise acclimation to high light and lead to a high chlorophyll fluorescence phenotype in Arabidopsis thalianaLight dependencies of ΦPSII and ΦPSI of HL- and LL-grown wild-type and mutant plants. The response of the quantum efficiencies of PSII (ΦPSII, A-D) or PSI (ΦPSI, E-H) towards increasing light intensities was determined with a DUAL PAM fluorometer for Col-0 wild type (A, E), the adg1-1 (B, F) or tpt-2 (C, G) single mutants as well as the adg1-1/tpt-2 double mutant (D, H) grown in HL (○) or LL (●). The data represent the mean ± SE of 12 independent measurements. Note that for some data the error bars are smaller than the symbol sizeBack to article page
