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 ...

MetabolomicsA multi-omics study on the metabolic reprogramming of a chlorophyll-deficient, high-protein Auxenochlorella pyrenoidosa mutant (CX41) generated by atmospheric and room temperature plasma (ARTP) mutagenesis.

This project aims to elucidate the molecular mechanism underlying the stable golden-yellow phenotype and enhanced protein accumulation in an Auxenochlorella pyrenoidosa mutant (CX41) generated by ARTP mutagenesis. Through comparative analysis between the wild-type (FACHB-9) and mutant s...

ProteomicsChlorophyll 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 the acclimation, the dynamic degradation/synthesis of tetrapyrrolic pigments as well as of the amino acid arginine is pivota...

ProteomicsIncorporation of chlorophyll a into Rhodobacter sphaeroides
Heterologous expression of a water soluble chlorophyll protein from Brassica oleracea var. gemmifera in the phototrophic purple bacterium Rhodobacter sphaeroides was verified by bottom-up proteomic analysis.

TranscriptomicsTranscriptome analysis of A661 leaves
The maize inbred line A661 shows a characteristic phenotype when grown at suboptimal temperatures for three weeks and then is exposed to optimal temperatures for one extra week. After this period the third leaf showed two well defined sections: distal (chlorophyll-less; CL) and proximal (chlorophyll...

TranscriptomicsTranscription profiling by array of Arabidopsis seedlings mutant for pif1
Arabidopsis bHLH transcription factor PIF1 has been shown function as a negative regulator of Chlorophyll biosynthesis. Pif1-2 mutant accumulate more protochlorophylide during prolonged dark growth condations, therefore the comparation between Wt and pif1-2 mutant will help us find the PIF1 target g...

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.

TranscriptomicsDigital gene expression analysis of ACMV-infected cassava
Cassava mosaic disease caused by cassava begomoviruses is the most serious disease of cassava in Africa. However, the molecular mechanisms leading to symptom development of infected cassava plants are poorly understood. Here a high throughput digital gene expression profiling (DGE) based on Illumina...

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...
