Characterization of the seedling lethal 1 (sl1) mutant. (A) Pigment-defective and seedling-lethal phenotypes of the sl1 mutant. The wild-type (WT) and sl1 mutant were grown on 1/2 Murashige and Skoog (MS) medium without or with 1, 2, or 4% sucrose (w/v) for 14 days. Experiments were repeated three times, with similar results obtained. (B) Fresh weight and chlorophyll content of the WT and sl1 plants are shown in (A). Three independent biological repetitions with 18 plants were performed for the analysis. (C) Chlorophyll fluorescence analysis of the WT and sl1 plants are indicated in (A). Fo, minimal fluorescence; Fm, maximal fluorescence; Fv/Fm, maximum efficiency of PSII photochemistry; NPQ, non-photochemical quenching. Three independent biological repetitions with similar results were performed for the analysis.
