MetabolomicsChlorophyll biosynthesis under the control of arginine metabolism.

In natural environments, photosynthetic organisms adjust their metabolism to cope with the fluctuating availability of combined nitrogen sources, a growth-limiting factor. For acclimation, the dynamic degradation/synthesis of tetrapyrrolic pigments, as well as of the amino acid arginine, is ...

TranscriptomicsA novel S-sulfocysteine synthase essential for chloroplast function in Arabidopsis thaliana
In bacteria, the biosynthesis of cysteine is accomplished by two enzymes that are encoged by the cysK and cysM genes. CysM is also able to incorporate thiosulfate to produce S-sulfocysteine. In plant cells, the biosynthesis of cysteine occurs in the cytosol, mitochondria and chloroplasts. Chloroplas...

ProteomicsQuantitative proteomic analysis of chlorophyll synthase-associated auxiliary proteins in Synechocystis photosystem II biogenesis using a FLAG-tag and 15N-labelled internal standards.
Photosystem II (PSII) is embedded in the thylakoid membranes of cyanobacteria and plant chloroplasts. PSII is the component of the photosynthetic apparatus that uses solar energy to split water, producing the oxygen in Earth’s atmosphere. PSII is a multi-subunit protein complex that requires several...

ProteomicsProteomic comparison of HliD and Ycf39 protein abundances in FLAG-tagged chlorophyll synthase co-immunoprecipitation assays of control and CrtR/CruF (carotenoid biosynthesis) knockout strains of Synechocystis sp. PCC 6803.
Chlorophyll a synthase (ChlG) is the enzyme responsible for attaching either a geranygeranyl or phytyl group to the chlorophyllide macrocycle during chlorophyll biosynthesis. Previous co-immunoprecipitation assays using FLAG-tagged ChlG identified the high light inducible protein HliD and the photos...

TranscriptomicsTranscription profiling of Arabidopsis plants with the chlorophyll removed by combining enhancer trap and RNAi approaches
Chlorophyll was removed from the veins of the C3 plant Arabidopsis by combining enhancer trap and RNAi approaches. Three independent transgenic lines were created. These were each compared to the parent line, J1511, in a microarray experiment.

ProteomicsEffects of the chlorophyll derivative 132-hydroxypheophytine a on zebrafish metabolomics
Zebrafish larvae were exposed from 3 DPF to 5 DPF to the chlorophyll derivative 13-2-hydroxypheophytine a. Metabolites were extracted with some modification of the protocol published by Lin et al 2019 (10.1016/j.bbrc.2019.04.003.). 3 experimental groups: DMSO 0.1% (solvent control) and hpa at 7.5 ug...

TranscriptomicsSuppressing the barley uroporphyrinogen gene by Ds activation tagging element generates developmental photosensitivity
Chlorophyll production involves the synthesis of photoreactive intermediates that are toxic when in excess due to the production of reactive oxygen species (ROS). A novel activation tagged barley mutant is described that results from antisense suppression of a uroporphyrinogen III synthase (Uros) ge...
