Hordeum vulgare mutants viridis-k, light green 3, light green 4 and zebra stripe 2 are not deficient in Ycf54. Both xanthan-l and viridis-k membranes are unable to support MPEC activity when combined with wild-type soluble fraction |

mutation of in enzyme MPEC causes the pale-green leaf mutant phenotype of mutant m167 with yellow-green leaves across the whole lifespan. Chlorophyll content decreases by 43-51% and the granal stacks of chloroplasts becomes thinner in m167. Chlorophyll fluorescence parameters, including Fv/Fm (the maximum quantum efficiency of PSII) and quantum yield of PSII (Y(II)), are lower in m167 than those in wild-type plants, and photosynthesis rate decreases by 40% in leaves of m167 mutant compared with wild-type plants, which leads to yield reduction in m167 |

Oryza sativa yellow-green leaf 8 (ygl8) mutant exhibits a chlorosis phenotype with abnormal chloroplast development in young leaves. During the development of leaves, the chlorotic plants turn green accompanied by restorations in chlorophyll content and chloroplast ultrastructure, expression levels of some nuclear genes associated with Chl biosynthesis are affected in both the ygl8 mutant and YGL8 RNA interference lines. YGL8 expression demonstrates no differences between the wild-type and ygl8 mutant plants, but the mutant shows increase of Proto IX and MgP/MgPME expression, accompanied with the decrease of protochlorophyllide.

the Arabidopsis chl27-t knock-down mutant has a T-DNA insertion within the promoter region reducing mRNA levels dramatically, growth is slowed down and plants look pale due to chloroplast development defects (unstacking of thylakoid membranes), chlorophyll fluorescence analysis shows a low photosynthetic activity, numerous nuclear genes involved in pigment biosynthesis, photosynthesis (light-harvesting complex I and II, photo system I and II), for iron acquisition, carbon fixation, cold acclimation, and for electron carriers are repressed, stress and detoxifying related gene expression is affected most prominently, more than 600 genes are repressed, a similar number of genes are induced |

the Ycf54 protein forms a complex with the component of the oxidative cyclase, Sll1214 (CycI, gene slr1780). Partial inactivation of the ycf54 gene leads to chlorophyll deficiency in cyanobacteria and plants, and the complete deletion of the ycf54 gene in the cyanobacterium Synechocystis 6803 results accumulation of huge concentrations of the cyclase substrate MgPME together with 3-formyl MgPME, in the DELTAycf54 strain. The Ycf54 protein is important, but not essential, for activity of the oxidative cyclase. Phenotype, overview |

| 1.14.13.81 | malfunction |
the yellow and spotted leaf 1 (ysl1) mutant in rice exhibits a yellow-green leaf phenotype throughout the whole developmental stage and a spotted leaf phenotype at seedling and tillering stages. The phenotype of ysl1 is caused by a single nucleotide substitution of Mg-protoporphyrin IX monomethyl ester cyclase YSL1 which is allelic to YGL8, OsCRD1, and YL-1 |
