Phenotypic characterization of the wild type and yl mutant plants. (A) Two-week-old wild type (left) and yl (right) seedlings. (B) Chlorophyll contents of the third leaf of the wild type (left) and yl (right) plants. (C) The Chl a/b ratio of the wild type (left) and yl (right) leaves. (D) The maximum photochemical efficiency of PSII measured by the Fv/Fm chlorophyll fluorescence ratio in the wild type (left) and yl (right) leaves. (E) The net photosynthesis rate of the wild type (left) and yl (right) plants. Error bars (B–E) represent the mean ± SD (n ≥ 3); ** indicates a significant difference at the 0.01 level. The p values were calculated by Student’s t-test. Bar = 5 cm in (A).
