Low Light (LL) and high light (HL) measurements. (A) Morphological phenotypes of each independent line during LL and HL evaluation. (B) Light curves were generated under LL and HL conditions for each of petM and wildtype “MoneyMaker” lines. Parameters indicated are electron transport rate (ETR), photochemical components of chlorophyll fluorescence quenching (qP), and CO2 assimilation rate. Non-linear one phase regression was performed for each line and parameter, reflected by their color. (C) Primary metabolomics changes in petM mutants under LL and HL conditions. Colors indicate different mutant lines and “MoneyMaker”. For the statistics, t-tests were performed for each mutant line against “MoneyMaker” under each growth condition, respectively. Significance levels are indicated as follows: * <0.05, ** <0.01 and *** <0.001. The arrow highlights the reference line, “MoneyMaker”. (D) Chlorophyll-a fluorescence and absorption measurements over LL and HL conditions. Depicted parameters include qL, Φ2, ΦNO, ΦNPQ, and vH+. Different lines are indicated in their respective color. The significance levels are depicted as * <0.05, ** <0.01, *** <0.001 and **** <0.0001, while ns refers to non-significant.
