General Information

General Information Comment Organism
malfunction the light-induced yellow leaf 1-1 (lyl1-1) mutant is hypersensitive to high-light and defective in the Chl synthesis. The mutation of LYL1 leads to conjugation of the majority of Chl molecules with an unsaturated geranylgeraniol side chain. The lyl1-1 mutant suffers from severe photooxidative damage and displays a drastic reduction in the levels of alpha-tocopherol and photosynthetic proteins. The yellowing of lyl1-1 mutant is caused by high-light stress. Mutant lyl1-1 phenotype, overview Oryza sativa Japonica Group
metabolism the three-step hydrogenation of geranylgeranyl diphosphate into phytyl diphosphate, and Chl-geranylgeranylated (ChlGG) and Chl-phytol (ChlPhy) is catalyzed by NADPH-dependent geranylgeranyl reductase. ENzyme LYL1 protects against lipid peroxidation and reactive oxygen species, ROS Oryza sativa Japonica Group
physiological function the enzyme is involved in the reduction step from Chl-geranylgeranylated (ChlGG) and geranylgeranyl diphosphate (GGPP) to Chl-phytol (ChlPhy) and phytyl diphosphate (PPP) in rice. Enzyme LYL1 also plays an important role in response to high-light in rice Oryza sativa Japonica Group
