formaldehyde/arabidopsis thaliana

Formaldehyde (FA) is a major industrial chemical and has been extensively used in the manufacture of synthetic resins and chemicals. The use of FA-containing industrial materials in daily life exposes human to FA extensively. Numerous studies indicate that FA is genotoxic, and can induce various

Variability of expression of formate dehydrogenase (FDH) caused by uptake of C-1 compounds was examined by using Arabidopsis thaliana as a model plant. Effects of uptake of several C-1 compounds were evaluated by Northern blot analysis using cDNA of A. thaliana FDH prepared by cloning on the basis

The control of gene expression by transcriptional regulators and other types of functionally relevant DNA transactions such as chromatin remodeling and replication underlie a vast spectrum of biological processes in all organisms. DNA transactions require the controlled interaction of proteins with

A cDNA from Arabidopsis thaliana resembling S-formylglutathione hydrolase (SFGH), an enzyme with putative roles in formaldehyde detoxification in animals and microorganisms, has been cloned and expressed in Escherichia coli. The purified recombinant Arabidopsis enzyme (AtSFGH) was a dimer composed

Formaldehyde (HCHO) is an air pollutant suspected of being carcinogenic and a cause of sick-house syndrome. Microorganisms called methylotrophs, which can utilize reduced C(1) compounds such as methane and methanol, fix and assimilate HCHO, whereas most plants are unable to assimilate HCHO directly.

Glutathione (GSH)-dependent formaldehyde dehydrogenase (FALDH) is a highly conserved medium-chain dehydrogenase reductase and the main enzyme that metabolizes intracellular formaldehyde in eukaryotes. It has been recently shown that it exhibits a strong S-nitrosoglutathione (GSNO) reductase activity

The proteins that are responsive to toxic volatile organic compounds (VOC) such as formaldehyde and toluene were analyzed with proteome analysis using two-dimensional difference image gel electrophoresis (DIGE) technology. Twenty-one days after germination (DAG) seedlings of Arabidopsis thaliana

Formaldehyde (HCHO) is suggested to be detoxified through one-carbon (C1) metabolism or assimilated by the Calvin cycle in plants. To further understand the function of the Calvin cycle and C1 metabolism in HCHO metabolism in plants, HCHO elimination and metabolism by Arabidopsis thaliana in HCHO

S-Formylglutathione hydrolase (SFGH) has activity toward several xenobiotic carboxyesters and catalyses the final step of formaldehyde detoxification: the hydrolysis of S-formylglutathione to formate and glutathione. The Arabidopsis thaliana enzyme (AtSFGH) was crystallized in space group C2, with

The information about DNA-binding sites of regulatory protein is important to understanding the regulatory network of DNA-protein interactions in the genome. In this report we integrated chromatin immunoprecipitation with DNA cloning to isolate genomic sites bound in vivo by heat shock factor HsfA1a

The fluorescence monitoring of formaldehyde in real environmental samples and live plant tissues is of great importance for physiological and pathological studies. However, there is a lack of suitable chemical tools to directly trace and measure the formaldehyde activity in bio-systems, and

The yeast Candida boidinii capable of growth on methanol proliferates and survives on the leaves of Arabidopsis thaliana. The local methanol concentration at the phyllosphere of growing A. thaliana exhibited daily periodicity, and yeast cells responded by altering both the expression of

S-Nitrosoglutathione (GSNO), an adduct of nitric oxide (NO) with glutathione, is known as a biological NO reservoir. Heterologous expression in Escherichia coli of a cDNA encoding a glutathione-dependent formaldehyde dehydrogenase of Arabidopsis thaliana showed that the recombinant protein reduces

Reverse transcription quantitative polymerase chain reaction (RT-qPCR) is widely used in diagnosis and research to determine specific mRNA expressions in cells. As RT-qPCR applications increase, it's necessary to provide undergraduates hands-on experience of this modern technique. Here, we report a

Eukaryotic gene transcription is associated with the eviction of nucleosomes and the formation of open chromatin, which enables the recruitment of transcriptional coactivators and other regulatory factors. Open chromatin is thus a hallmark of functional regulatory DNA elements in genomes. In recent
