the ygl8 mutation causes a conserved amino acid substitution, which is related to the alterations of chlorophyll precursor content
A96T
site-directed mutagenesis, the point mutation in OsCRD1 does not change its location, but leads to deficiency in chlorophyll biosynthesis and chloroplast development and decreases photosynthetic capacity in rice, phenotype
G286A
naturally occurring mutation, the mutation in enzyme MPEC causes the phenotype of the rice pale-green leaf mutant m167, phenotype
additional information
additional information
mutant plants are complemented with enzyme construct fused to GFP at C-terminus under native promoter or a constitutive 35S-promoter control, suppressing the mutant phenotype, N-terminal deletion of the first 39 amino acids leads to location in the cytosol instead of chloroplast membrane (crucial localization signal)
additional information
silencing of gene CHL27 by siRNA overexpression, encoding the CHLH subunit of enzyme Mg protoporphyrin monomethylester cyclase, for more than 24 h results in necrotic leaf lesions and modulated transcript levels of oxidative stress-responsive and photosynthesis-associated nuclear genes (PhANGs), transcriptome analysis, phenotypes, overview

identification of a xantha-l mutant, defective in a gene of Mg-protoporphyrin monomethyl ester cyclase, the mutant does not show the gun mutant phenotype, that is defective in the chloroplast-to-nucleus signal transduction and expresses Lhc even when chloroplast development is inhibited by the herbicide norflurazon, the xantha-181 mutant can synthesize Mg-protoporphyrin IX and Mg-protoporphyrin IX monomethyl ester, phenotype, overview

-
generation of subunit YL-1 mutants yl-1, phenotype, overview. 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

isolation of an Oryza sativa yellow-green leaf 8 (ygl8) mutant that exhibits 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. Phenotype, overview. Ygl8 knockout by RNAi
additional information
mutant m167 is isolated from a EMS mutagenized population from the Japonica rice variety Kitaake. To construct the F2 mapping population, the yellow-green leaf rice mutant m167 is crossed with rice varieties Zhefu802 and Dular, respectively, genotyping of F2 population
additional information
yellow and spotted leaf 1 (ysl1) mutant in rice exhibiting a yellow-green leaf phenotype throughout the whole developmental stage and a spotted leaf phenotype at seedling and tillering stages. Genetic analysis indicates that a single recessive gene is responsible for the phenotype of ysl1 mutant. Map-based cloning shows that the mutation site is located at the region of 105.4-kb between RM572 and L3 on the short arm of chromosome 1. Sequence analysis reveals that a point mutation (C-to-T) happens in the coding region of candidate gene YSL1 (LOC_Os01g17170) which causes an amino acid change in MPEC. Mutant phenotype analysis. Growing under natural conditions, ysl1 mutant exhibits a yellow-green leaf in the whole developmental stage and slow growth comparing with its wild-type. Besides, the spots appear in the leaves of the mutant at seedling and tillering stages, are reduced at heading stage, and disappear at mature stage. Most of the main agronomic traits significantly decrease in the mutant. For example, plant height, number of productive panicles per plant, number of spikelets per panicle, seed setting rate, and 1000 grain weight decrease by 16.8%, 20.7%, 17.8%, 7.3%, and 10.6%, respectively, while the days to heading significantly increase by 12.1%

the lack of the BluB protein function in Rhodospirillum rubrum is reflected by the impaired ability of a DELTAbluB strain to synthesize cobalamin and to convert Mg-protoporphyrin IX monomethyl ester into protochlorophylide catalyzed by the MPE-cyclase enzyme, phenotype, overview

construction of a mutants lacking chlAI, chlAII, slr0905, sll1242, or slr0309, respectively, the DELTAchlAI mutant fails to grow under aerobic conditions with anomalous accumulation of a pigment with fluorescence emission peak at 595 nm, the growth defect is restored by the cultivation under oxygen-limited micro-oxic conditions. MPE accumulation is also detected in DELTAchlAII mutant grown under microoxic conditions, but not in any of the bchE mutants. The phenotype is consistent with the expression pattern of two chlA genes: chlAII was induced under micro-oxic conditions in contrast to the constitutive expression of chlAI, phenotypes, overview
