Isolation and Characterization of a Rhodobacter Capsulatus hemC Mutant. [PDF]

, 2001
Rhodobacter capsulatus, a purple, nonsulfur photosynthetic bacterium, uses the tetrapyrrole pathway to synthesize four end products: heme, bacteriochlorophyll, vitamin B12, and siroheme. This laboratory has focused on the regulation of the common pathway

Deletion of the gene encoding the magnesium chelatase I subunit resulted in a novel wheat leaf colour mutant

Plant Biotechnology Journal, Volume 23, Issue 10, Page 4290-4301, October 2025.
Summary Leaf colour mutants are ideal germplasm resources for investigating the mechanisms of chlorophyll (Chl) synthesis, chloroplast development and photosynthesis. In this study, we obtained a yellow‐leaf mutant, designated SN288‐2. The variant presented a yellow‐leaf phenotype and halted the development of chloroplasts at the seedling stage, with ...

A Mg‐Chelatase Subunit I Missense Mutant in Barley Exhibits a Cold‐Sensitive Phenotype Under Field Conditions

Physiologia Plantarum, Volume 177, Issue 4, July/August 2025.
ABSTRACT The pale‐green barley mutant xan‐h.chli‐1 has a HvCHLI subunit of Mg‐chelatase with an Arg‐to‐Lys substitution at position 298 and exhibits a unique cold‐sensitive phenotype. Under winter field conditions, xan‐h.chli‐1 plants fail to survive, whereas they thrive under spring or greenhouse conditions. Controlled experiments show a specific cold‐

Dermatologic manifestations of hereditary hemochromatosis: A systematic review

Journal of the European Academy of Dermatology and Venereology, Volume 39, Issue 5, Page 976-986, May 2025.
Abstract Hereditary hemochromatosis (HH) is a genetic disorder leading to excessive iron absorption, impacting multiple organs, notably the skin, nails and mucosae. The objective of this study is to elucidate the dermatologic manifestations, associated symptoms, pathophysiology and management recommendations of HH.

Specific effects on liver relevant for performing a dietary cumulative risk assessment of pesticide residues

EFSA Journal, Volume 23, Issue 5, May 2025.
Abstract According to the ‘EFSA‐SANTE Action Plan on Cumulative Risk Assessment for pesticides residues’, EFSA initiated a retrospective cumulative risk assessment (CRA) of the effects of pesticide residues on the liver. For this CRA, EFSA identified the following liver‐specific effects in accordance with the International Harmonisation of Nomenclature

Sister Dehalobacter Genomes Reveal Specialization in Organohalide Respiration and Recent Strain Differentiation Likely Driven by Chlorinated Substrates [PDF]

, 2016
The genomes of two closely related Dehalobacter strains (strain CF and strain DCA) were assembled from the metagenome of an anaerobic enrichment culture that reductively dechlorinates chloroform (CF), 1,1,1-trichloroethane (1,1,1-TCA) and 1,1 ...
