General Information

General Information Comment Organism
evolution phylogeny of the YL-1 protein family, overview Oryza sativa
malfunction chlorophyll biosynthesis upstream genes are highly expressed in the yl-1 mutant, while downstream genes are compromised, indicating that enzyme MPEC plays a pivotal role in the chlorophyll biosynthesis. The yl-1 mutant shows a yellow leaf and panicle phenotype with reduced chlorophyll accumulation through the whole growth phases. Mutant yl-1 exhibits the temperature-independent yellow leaf phenotype, it presents abnormal chloroplast development and attenuated photosynthetic efficiency. The mutant yl-1 affects mRNA accumulation levels of Chl biosynthesis process Oryza sativa
physiological function an essential enzyme during chlorophyll (Chl) biosynthesis. The enzyme subunit protein YL-1 is required for plastid membrane stability. The formation of the isocyclic ring is an aerobic reaction catalyzed by MPEC in chloroplasts, which controls the conversion of magnesium-protoporphyrin IX 13-monomethyl ester to divinyl protochlorophyllide (DVpchlide). The function of YL-1 in MPEC complex is essential for normal chlorophyll biosynthesis Oryza sativa
